Description

BACKGROUND

1. Technical Field

The present invention relates to robots, and particularly, to component control modules of robots.

2. General Background

Pet robots are becoming popular toys nowadays. Pet robots are made to look like and imitate dogs, cats, dinosaurs, and so on. However, one disadvantage of pet robots is that they respond slowly to outside information.

An example of pet robots is shown in FIG. 1. The pet robot is a dinosaur 50.

The dinosaur 50 acquires outside information by sensors which are located all over the body thereof, and acts by actuators which are connected to joints of the body. The sensors and the actuators are located as follows: each leg includes an actuator 110 located on an upper end for controlling the leg to rotate, an actuator 111 located on the ankle for allowing movement of the feet, a touch sensor 112, and a press sensor 113 located on the sole of the feet; the tail includes an actuator 120 for controlling the tail to rotate vertically, an actuator 121 for controlling the tail to rotate horizontally, and a touch sensor 122; the back includes an actuator 130; the neck includes an actuator 140 for controlling the neck to rotate vertically, an actuator 141 for controlling the neck to rotate horizontally, a touch sensor 142, and two sound sensors 143; the head includes an actuator 150, a touch sensor 152, and an image sensor 154.

A control system of the dinosaur 50 is disclosed in FIG. 2. The dinosaur 50 includes a CPU (central processing unit) 56, a plurality of controllers 61 (only two controllers 61 are shown in FIG. 2), a plurality of actuators 72 (only two actuators 72 are shown in FIG. 2), and a memory 73. The CPU 56 connects with the controllers 61 and the actuators 72. Each controller 61 connects with a plurality of sensors 62. The actuators 72 are not unlike the actuators 110, 111, 120, 121, 130, 140, 141, 150 mentioned in FIG. 1. The sensors 62 are not unlike the sensors 112, 113, 122, 142, 143, 152, 154 mentioned in FIG. 1. The actuators and the sensors are respectively referred to by single reference in FIG. 2 so that the control system of the dinosaur 50 can be concisely presented.

The memory 73 stores the dinosaur 50's action instructions, status information, and relationships between outside information, the status information and action instructions, etc. According to an action instruction, the CPU 56 can produce a plurality of sub-action instructions and control corresponding actuators 72 to perform an action. The outside information is detected by sensors 62, includes light signals, touch signals or sound signals, etc. The status information represents the dinosaur 50's status, includes resting, moving, etc.

The sensors 62 detect outside information and send out detection results as sensing signals to controllers 61. The controllers 61 send the sensing signals to the CPU 56. The CPU 56 gets the outside information on the basis of the sensing signals, gets the current status information from the memory 73, gets an action instruction from the memory 73 according to the outside information and the current status information, produces sub-action instructions according to the action instruction, and controls corresponding actuators 72 to perform an action according to the sub-action instructions. The CPU 56 deals with too much information and as a result is usually slow to respond to a sensing signal. Thus, the dinosaur 50 responds slowly to outside information.

Therefore, what is needed is a robot which responds quickly to outside information.

SUMMARY

In step S1, when detecting the outside information, the sensor 210A generates the sensing signal and sends the sensing signal to the direct response unit 202A. In step S2, the direct response unit 202A receives the sensing signal, gets a response instruction corresponding to the sensing signal from the memory 230A, and controls actuators 220A to perform an action according to the response instruction.
