The head 10 of the robot 1 may include an image sensor (e.g., RGB-D camera) configured to capture images of an object or the environment. The head 10 of the robot 1 may include a microphone configured to capture a voice or sound of an object or the environment. The head 10 of the robot 1 may include a display and a speaker to provide an expression or to show information (e.g., a facial expression, a voice, a sound effect and the like). In some embodiments, the head 10 of the robot 1 may include a lighting device (e.g., LED) configured to emit a light beam.
The body 11 of the robot 1 may include various kinds of processing units configured to calculate or process images, information or data obtained by the robot. In some embodiments, the processing units may include a central processing unit (CPU), a complex programmable logic device (CPLD), a field-programmable gate array (FPGA), a graphic processing unit (GPU), and/or an application-specific integrated circuit (ASIC). The body 11 of the robot 1 may include a real-time operating system (RTOS) configured to serve real-time applications that process data as it comes in, typically without buffer delays. In some embodiments, the body 11 of the robot 1 may include an emergency button configured to shut down or terminate the robot.
The base 12 of the robot 1 may include various kinds of sensors (e.g., sonar, Lidar, odometry, inertial measurement unit (IMU) and the like) configured to receive, detect or recognize information (e.g., physical signal) from an object or an environment. In some embodiments, a battery may be located at the base 12 of the robot 1 and configured to power the robot 1. In some embodiments, the battery is not removable, and thus the robot can be disposed on a charging dock to charge the battery. In other embodiments, the battery is removable, and thus the battery can be disposed on the charging dock directly.
The arm 13 of the robot 1 may include motors, a gear reducer, a drive plate, a screw rod and a joint configured to drive the arm to perform a movement or action. The arm 13 of the robot 1 may further include an encoder configured to detect the position or the movement of the arm and to determine whether the movement of the arm is reached the limitation. The arm 13 of the robot 1 may include a microcontroller unit (MCU) configured to control the movement or action of the arm 13. In some embodiments, the arm 13 of the robot 1 may include a temperature/current sensor configured to detect or measure the temperature or the current of the motor to check whether the loading of the arm is within a threshold. If so, the MCU is configured to terminate the action of the arm 13 until the temperature or the current measured by the temperature/current sensor is less than the threshold.
The end-effector 14 of the robot 1 is disposed at the distal end of the arm 13 and configured to perform a particular task, such as grasping a work tool or stacking multiple components. The end-effector 14 may include an image sensor (e.g., wrist camera) configured to capture the images of an object to be touched or grasped and/or to detect the location or the relative position between the object and the end-effector 14. The end-effector 14 may include a fiducial or fiducial marker (MUD) configured to identify a particular marker within the current image view. The end-effector 14 may further include a force sensor configured to detect or measure the force applied to the object by the end-effector 14.
In some embodiments, the head 10, the body 11, the base 12, the arm 13 and the end-effector 14 of the robot 1 can be connected and communicate to each other through a communication protocol (e.g., RS-485) to perform a plurality of actions. For example, the robot 1 can be configured to perform any of the followings actions: talking, 2D or 3D images capture or reconstruction, objects and environments detection, grasping, lifting or moving objects, visual serving, compliance controlling, navigation, obstacle avoidance and/or infrastructure. In some embodiments, the robot can be installed with any kinds of operation systems, applications, software and/or firmware depending on different requirements. In some embodiments, the operation systems, applications, software and/or firmware can be updated automatically or manually. In some embodiments, the robot 1 is configured to perform self-learning. For example, the robot 1 can be connected to the Internet or cloud by its communication module to search information in response to various situations and to perform an action based on the information from the Internet or cloud.
In some embodiments, the robot 1 can be controlled by a controller, such as a remote (or wireless) controller or a wired controller. For example, a user may input a command or instruction to the controller (e.g., push buttons of the controller) to request the robot 1 to perform actions. However, as the actions performed by a robot become more complicated, the number of the buttons of the controller should increase, which would increase the price or the size of the controller. In some embodiments, the robot 1 may be controlled by entering a series of buttons (e.g., a combination of multiple buttons). For example, one action of the robot can be performed by entering more than one buttons. However, although this may reduce the number of the required buttons of the controller, it is inconvenient for users to remember or check the correspondence between the combination of the buttons and the action performed by the robot 1.
In some embodiments, the robot 1 can be controlled by a voice input. For example, the robot 1 may be equipped with voice recognition module, also known as Automatic Speech Recognition (ASR), which can transform the vocabulary in human language into computer readable input, such as buttons, binary coding or character sequence. However, due to the limitation of the voice recognition technique, a distortion or an error may occur when transforming the human language into computer readable information. In addition, there are too many types of languages existing in the world and even in one language, a single action or command can be expressed by different words, phrases and/or sentences. Therefore, a relatively large database or memory is required for the robot 1 to store the information and a processor with a higher speed is also required to process such a huge data or information, which would increase the price of the robot 1.
In some embodiments, the robot 1 may be controlled by an image, a photo or a picture. For example, the robot 1 may be equipped with a 2D or 3D image recognition module to transform 2D or 3D images captured by the robot 1 into computer readable information. However, to reconstruct the captured 2D or 3D images, a processor with a higher speed is required. In addition, a relatively large database or memory is also required to store the information corresponding to the 2D or 3D images, which would increase the price of the robot 1.
Referring to operation S21, an input corresponding to a first code is entered by, for example, a user. In some embodiments, the first code can be a binary code, an octal code, a decimal code, a hexadecimal or any other computer readable codes. In some embodiments, the input may be an electronic message or an image data, such as an emoji or a sticker entered by the user on an electronic device (e.g., a mobile phone, a tablet, a notebook, a computer, a smart watch, a smart bracelet, a smart glasses and the like). Each electronic message includes or corresponds to a code formed by one or more bits of data units. For example, an emoji and a corresponding code can be converted based on Unicode blocks.
Referring to operation S22, the first code is then converted into a second code (a signal, controlling signal and the like). In some embodiments, the second code can be a binary code, an octal code, a decimal code, a hexadecimal or any other computer readable codes. In some embodiments, the entered input is transmitted from the user's electronic device to the robot 1 and the robot 1 is configured to convert the first code into the second code. Alternatively, the user's electronic device is configured to convert the first code into the second code and then to transmit the second code to the robot 1. In some embodiments, the first code and the second code include different numbers of bits or characters. For example, the first code may be formed by N bits or characters, and the second code may be formed by (N+M) or (N−M) bits or characters, wherein N and M are integers. In some embodiments, the first code and the second code are formed by the same number of bits or characters, but they are encoded by different coding methods (or scheme).
Referring to operation S23, the robot 1 is controlled by the second code or a portion of the second code. For example, the second code or a portion of the second code corresponds to an action or multiple actions of the robot 1. In some embodiments, if the first code is formed by N bits or characters and the second code is formed by N+M bits or characters, the N bits or characters of the first code or the second code can be used for the expression of the electronic message (e.g., the emoji or the sticker) while the M bits or characters of the second code is used to control the robot 1. In other embodiments, if the first code and the second code are formed by the same number of bits or characters but are encoded by different coding methods, the first code can be converted into the second code according to, for example, a conversion table (or a lookup table). In some embodiments, the conversion operation may be performed at the user's electronic message, a cloud, a server or the robot 1 depending on different requirements.
As shown in
The first code can be transmitted to a screen 31 to display the emoji 301 (or sticker) on the screen 31. In some embodiments, the screen 31 may be included in any kinds of electronic devices (e.g., a mobile phone, a tablet, a notebook, a computer, a smart watch, a smart bracelet, a smart glasses and the like) or the robot 1. For example, after the user enters the emoji 301 (or sticker), the first code corresponding to the emoji 301 (or sticker) is transmitted to the screen 31 or the electronic device including the screen 31, and then the screen 31 is configured to display the emoji 301 (or sticker) entered by the user according to the first code.
In some embodiments, after the user inputs the emoji 301 (or sticker), the first code is also converted into a second code, and the second code is then transmitted to the robot 1 to instruct or operate the robot 1 to perform an action or actions. In other embodiments, after the user inputs the emoji 301 (or sticker), the first code is transmitted to the robot 1 and then converted into the second code to instruct or operate the robot 1 to perform an action or actions. In some embodiments, the conversion operation between the first code and the second code is performed according to the operations S21, S22 and S23 shown in
For example, when the user enters an emoji (or sticker) showing an icon of beer on his/her electronic device 30, the icon of beer will be displayed on the screen 31 of the electronic device 30 or other electronic device. The first code corresponding to the icon of the beer is converted into the second code (the conversion operation may be performed at the user's electronic device, the robot 1 or other devices) corresponding to an action or actions of the robot 1. After the robot 1 receives the second code, the robot is configured to perform an action or actions corresponding to the second code. For example, the icon of beer may correspond to a command or instruction to request the robot 1 to grab a bottle of beer for the user, and thus the robot 1 will find a bottle of beer and take it to the user after the icon of beer is entered by the user.
