The subject matter disclosed in this application generally relates to robots, and more specifically, to robotic toys, such as a biomimetic children's toy, remote-controlled toy, crawler robot, autonomous robot, or any other suitable robot or combination of robots.
Smart Composite Microstructure (SCM) technology is a manufacturing process that was originally developed at UC Berkeley for the construction of robots at the millimeter scale. This technique can generate robot components (SCM components) for fast assembly. The process starts with combining two rigid layers and a flexible layer in a laminate structure to form a sheet. The flexible layer, which is frictionless, scales well to small structures. Once the flexible layers are sandwiched between the rigid layers, the sheet is generally carved using a laser cutter to expose the flexible layer. The end product is a flat structure with lines of exposed flexible layer. The flat structure is then folded into a final three-dimensional shape to create a useful device.
SCM components by themselves are not ideal for making robotic toys for children. Robots made entirely out of SCM components are too fragile. For instance, a SCM chassis is likely to break into pieces upon falling to the ground, thus causing damage to the enclosed electronics. In some instances, it may be too expensive to make a robot chassis entirely out of SCM components. As for assembly, tiny tools such as tweezers are usually required for building a robot with SCM components. This is not ideal for robot toys. Robotic toys for children should be easily constructible by hand without the need for sharp tools. Therefore, to make the SCM technology suitable for robotic toys, a new design is needed.
In some embodiments, a robot with flexible mechanics and locomotive capability is provided. The robot has at least one Smart Composite Microstructure (SCM) component with flexible mechanics, a rigid module connected to the at least one SCM component, and at least one internal component that provides locomotive capabilities to the robot.
In some embodiments, the SCM components are composed of two rigid layers with a flexible layer sandwiched in between. In some embodiments, the SCM components have a first flat structural region with an integral flexible layer sandwiched between two rigid layers, a second flat structural region with the integral flexible layer sandwiched between another two rigid layers, and a bendable joint region connecting the first and second flat structural regions composed of just the integral flexible layer. In some embodiments, the integral flexible layer is made of a bendable material. In some embodiments, the bendable material is flexible and has a tear resistance greater than 10 N.
In some embodiments, the robot is a toy robot, biomimetic toy, remote-controlled robot, crawler robot, autonomous robot, or any other suitable robot or combination of robots. In some embodiments, the rigid module functions as a rigid spine of the robot. In some embodiments, the rigid module functions as a chassis for the robot. In some embodiments, the rigid module provides at least one connecting terminal for a SCM component. In some embodiments, the internal component is a motor with at least one motor output. According to some embodiments, at least one SCM component is connected to the motor output such that the internal component could cause the robot to move by actuating the connected SCM component.
In some embodiments, an assembly system with one or more assembly indicators is provided. In some embodiments, the assembly system requires multiple assembly indicators to work together to ensure an error-free assembly process. In some embodiments, the SCM components and the rigid module employ unique indentation and protrusion patterns to reduce the chance of misconnections. In some embodiments, the SCM components and the rigid module employ a marking system to highlight the correct connection terminal.

The invention presented here describes a three-dimensional (3D) robot with flexible mechanics and locomotive capability. In some embodiments, the robot is designed as a toy robot. In some embodiments, the robot is configured to simulate the appearance and movement of an insect. In some embodiments, the robot has shock-absorbing feet made out of SCM components and a hard-shell body to protect the electronics inside. The shock-absorbing feet are designed to allow the robot to travel over a surface swiftly. The hard-shell body is designed with connector terminals to allow SCM components to attach. The hard-shell body can take on the appearance of different species of insects such as ladybugs, scorpions, beetles, grasshoppers, or any other suitable insects. In some embodiments, the hard-shell body can take on the appearance of any other suitable objects such as cars, dinosaurs, or other animals.
The present disclosure also includes a unique assembly system designed to help assemblers with no robot building experience to construct the robot in an efficient manner. According to certain embodiments, the SCM components are printed on a SCM sheet with incision lines to facilitate easy detachment. Fabricating SCM components on a SCM sheet is not only cost effective but also ensures that all the components are produced for assembly. According to certain embodiments, the SCM components are labeled with various assembly indicators. These indicators are designed to assist the builders in connecting parts of similar shapes and sizes to the right location.
According to certain embodiments, the 3D robot is composed of one or more Smart Composite Microstructure (SCM) components with flexible mechanics, a rigid module connected with at least one of the one or more SCM components, and at least one internal component sandwiched between the rigid module and SCM components. The at least one internal component is configured to mobilize the robot. In some embodiments, the SCM components described here are the same SCM component disclosed in U.S. patent application Ser. No. 14/679,143, titled “COMPOSITE MICROSTRUCTURES,” which is incorporated by reference in its entirety.
The SCM components described herein are made of multiple structural layers.
In some embodiments, the integral flexible layer 104 is made of a flexible material that can be molded to an effective thickness. According to some embodiments, the effective thickness is between 15 to 150 microns. However, the effective thickness can be any other suitable size or range. The flexible material should provide a proper level of “springiness” in the joint region 110 such that the SCM component can be bent into a 3D configuration and then remain in that shape thereafter. Ideally, the integral flexible layer should not be overly thick. An excessive stiffness in the joints due to an overly thick flexible layer may reduce movement efficiency and require excessive energy output to operate. On the other hand, the integral flexible layer should not be too thin. A thickness below the effective range may be too yielding and not able to hold shape or provide sufficient structural support.
In some embodiments, the integral flexible layer 104 is made of a flexible material with sufficiently high tear strength. In some embodiments, the flexible layer material in the SCM components can withstand upward of 10 N, or any other suitable N value, of force before tearing. A material with a tear resistance above 10 N can generally withstand normal assembly and operation. If the flexible material has a tear resistance significantly below 10 N, the chances of tearing during normal assembly and use rises greatly. In some embodiments, ripstop nylon is used for the integral flexible layer. In some embodiments, ripstop dacron is used for the integral flexible layer. Other suitable materials or combination of materials with similar tear strength can also be used.
According to some embodiments, the rigid module 408 is not made by the SCM technology. In some embodiments, the rigid module 408 has a window 410 for housing sensors, recording devices, lights, or other electronic components. In some embodiments there can be multiple windows on multiple sides of the rigid module. In some embodiments, the top side of the rigid module 408 contains connecting hubs for adding other robot features.
Various materials can be used for constructing the rigid module including but not limited to metal, plastic, fortified plastic, fiberglass, wood, aluminum, steel, or any other suitable material or combination of materials. In some embodiments, two or more subparts are connected together to make the rigid module. For example, rigid module 408 has a top component in white, a bottom component in dark gray, and multiple black bolts securing the top and bottom components. In some embodiments, the outer part of the rigid module is transparent, opaque, or translucent. In some embodiments, the inner part of the rigid module has a cavity for housing various components such as a motor, electronic circuit, battery etc. According to some embodiments, the one or more guiding channels are connected to the bottom the rigid module. In some embodiments, the rigid module has a single unibody structure with no connecting subparts.
According to some embodiments, rivets 412 are manufactured separately from the rigid module 408 and the SCM component sheet 402. The rivets can be made of any suitable material such as a plastic, thermoplastic, metal, wood, fiberglass, aluminum, or combination thereof.
In some embodiments, when the robot is mobilized, the legs move in a synchronized fashion to cause the robot to travel forward or backward. In some embodiments, the left-side legs and right-side legs move as two separate units. In some embodiments, the left set of legs and right set of legs move in an alternating fashion such that when the right set legs are rotating towards the ground the left set legs are rotating off the ground. Depending on the speed of the onboard motor, this alternating motion can occur many times per second to allow the robot to travel at a fast pace. According to some embodiments, one set of legs can move faster than the other set of legs and thus causes the robot to turn. According to certain embodiments, the robot mimics the traveling motion of a crawler insect such as a scorpion.
Although not visible in
The internal component can be any device capable of setting the robot in motion by moving the connected SCM components. The internal component can be a battery, actuator, or motor powered by electricity, fuel, or other suitable energy source such as light. In some embodiments, the internal component is a windup mechanism. In some embodiments, the movement of the robot is dictated by the design and configuration of the internal device. For example, if the robot is designed for underwater travel the internal device can be a motor configured to drive the propellers. If the robot is a helicopter robot, the internal component can be a motor configured to power the helicopter blades. In some embodiments, more than one motor component is placed inside the robot.
In some embodiments, the inside of the rigid module is compartmentalized to house various electronic devices. Besides the motor discussed above, in some embodiments the rigid module houses one or more circuit boards, processors, memories, wireless communicators, multi-axis accelerometers, multi-axis gyroscopes, infrared (IR) transmitters, various sensors such as IR, vibration, and optic sensors, lights such as LED lights and laser, onboard cameras, microphone, speakers, and any other suitable component or combination thereof. In some embodiments, one or more of these components work together to allow remote programing of the robot. In some embodiments, one or more of these components work together to allow wireless control of the robot. In some embodiments, a light source is placed inside an opaque or translucent rigid module such that the color change can be readily observed.
In some embodiments, the robot is configured to establish wireless connection with a controller via wireless transmission (for example, home RF or Wi-Fi). In some embodiments, the communication protocols include Bluetooth, Zigbee, IEEE 802.11, or other cellular standards or combination of standards. According to certain embodiments, the controller is a phone, computer, electronic tablet or other suitable device with a programmable user interface.

In some embodiments, the robotic 600 may include additional components, fewer components, or any other suitable combination of components that perform any suitable operation or combination of operations.
The following paragraphs will discuss the assembly system in more detail, including various connecting mechanisms. Although the connecting mechanisms are described in a particular order, different assembly orders are within the scope of this invention. In some embodiments, a complete assembly requires all connecting mechanisms/steps described herein. In some embodiments, only one connecting mechanism/step described herein is required.
Rivets with a unibody push-and-lock mechanism provide certain advantages for the assembly process. First, this design reduces the amount of assembly components needed to be accounted for during an assembly process. Second, compared to the two-part fastening mechanisms (e.g., the one disclosed in 816), this design reduces the chance for missing parts. A missing sub part can lead to a frustrating assembly experience. Third, this rivet design is ideal for securing SCM components into a tight or unreachable back space. Once the rivet is pushed into the components, the component is secured. The assembler does not need to deal with aligning a separate component from the backside. It is especially useful in certain embodiments where the robot is designed for small children or assemblers with no robot building experience.
The unibody push-and-lock rivets described herein can be made of any appropriate materials, such as plastic, rubber, thermoplastic or fiberglass. While certain embodiments employ the unibody push and lock rivets, other fastening mechanisms could also be used. Other suitable fastening mechanisms include buckle tabs, snap clasps, screws, magnets, etc.
In some embodiments, the matching indicators or markings can be of the same letters, numbers, colors, or symbols. In some embodiments, the matching indicators can be of a different or complementary letter, number, color, or symbol. For instance, a component with a “+” symbol may be connected to a component with a “−” symbol. Other comparable labeling schemes (for example, numbered parts or matching symbols) may also be employed. In some embodiments, multiple matching indicators are used to label each SCM component. In some embodiments, a matching rule can be used in conjunction with matching indicators.
Together,
The indentation-protrusion system prevents similar parts from connecting to the wrong terminals. Even if the assembler overlooked the letter indicators and mistakenly inserted a component into the wrong terminal, the terminal would reject the connection. That is, the component would not be able to achieve a proper connection for the fastening component to push through. As shown in 1118, only a proper connection would allow a rivet to secure the SCM component. This added mechanism further reduces the chance of misconnection.
Referring back to
At step 1402, at least one two-dimensional (2D) SCM component is created. In some embodiments, the process for creating a 2D SCM component includes sandwiching an integral flexible layer between a first rigid layer and a second rigid layer to make an SCM board, removing a portion of the first and the second rigid layers on the SCM board to expose a portion of the integral flexible layer, and cutting the at least one SCM component from the SCM board. In some embodiments, more or less steps are involved in the process. According to some embodiments, the at least one SCM component has a first flat structural region connected to a second flat structural region via a bendable region composed of the exposed portion of the integral flexible layer similar to the configuration illustrated in
At step 1404, the at least one 2D SCM component is folded into a three-dimensional configuration (becomes a 3D SCM component). In some embodiments, the 2D SCM component is folded along the bendable region. In some embodiments, the folding process includes slightly bending or tilting the at least one 2D SCM component so that when a flat structural region is in full contact with a flat surface, the other flat structural surface does not contact the flat surface. In some embodiments, once the SCM component is folded, it stays in the folded configuration (e.g., the bendable region would stay bent). The process 1400 then proceeds to step 1406.
At step 1406, the 3D SCM component is connected to a rigid module by a connection terminal on the rigid module. In some embodiments, the 3D SCM component is indirectly connected to the rigid module via another object. In some embodiments, the connection terminal is a receptacle, adapter, link, coupling, joint, socket, channel, or a combination thereof. Various connection mechanisms may be implemented; for example, slide-and-click latches, pins, grooves, notches, rotary engagement latches, click-and-lock tabs, or a combination thereof. In some embodiments, step 1406 includes an additional securing step after the connection is made. The securing step may involve fastening the connected 3D SCM component with at least a rivet, nail, screw, link, buckle, or a combination thereof.
According to some embodiments, at least one connection is made according to an assembly indicator. In some embodiments, no assembly indicator is involved. In some embodiments, components with similar site indicators are connected near one another. In some embodiments, multiple assembly indicators work together to ensure that only the correct connections are made. In some embodiments, wrong connections would prevent the assembler from properly securing the component. The process 1400 then proceeds to step 1408.
At step 1408, the at least one 3D SCM component is connected to an internal component housed in the rigid module. In some embodiments, the internal component is partially enclosed by the rigid module. According to some embodiments, the internal component is a device configured to locomotive capability to the robot; for example, a battery, actuator, motor, wind-up mechanism, or a combination therefore. In some embodiments, the internal component has more or less than two output connectors. In some embodiments, the connection is made by pushing the pole-clamping interface of the at least one 3D SCM component onto an output connector. See for example
At step 1410, the robot is ready to be activated. In some embodiments, the robot is activated to allow the robot to execute a programmed action such as flashing lights, spin, run, vibrate, dance, battle, record images or sounds, make noise, or a combination thereof. The robot can be activated via various methods. In some embodiments, the robot is activated by an on and off switch on the robot. In some embodiments, the robot is activated by a wireless signal. In some embodiments, the robot is activated by connecting to a computer. In some embodiment, the activation step involves programing the robot. In some embodiments, the robot can self-program once it is connected to a network. In some embodiments, the user can remotely program the robot via a user device. In some embodiments, once the robot is activated, the user can control the direction the robot travels.
