Abstract: A miniature mobile robot facing on precision manipulation is developed and the wireless control system is designed. This robot is composed of moving allocation unit basing on macro/micro dual moving manner and spherical manipulator with three degrees of freedom. The whole robot occupies a volume of 90 mm′70 mm′60 mm. In the macro-moving manner, using the micro motor with the diameter of 3 mm, the robot can move at high speed up to 100 mm/s. And the posi-tioning accuracy is up to 0.5 mm as well as the moving resolu-tion is 0.1 mm. In the micro-moving manner, according to prin-ciple of inchworm, the robot can move at a speed of 200 μm/s with 50 μm positioning accuracy and 2 μm resolution. Three pizeo-ceramic tubes basing on the principle of stick-slip drive the spherical manipulator. The manipulator can rotate around z-axis or move up and down. The accuracy of spherical manipulator is 0.001°. All driving circuits are integrated in the body of robot. Two polymeric lithium-metal cells are selected as the power source. The robot communicates with the image processing system through a blue tooth model. For convenient control, the locomotion of robot is decomposed several sample motion modes. By applying the multiple threads technology to program, the performance of real time operation is good.
