Abstract:
1. A mobile robotic device capable of collision detection, comprising: a base frame having two guide grooves and two openings, said guide grooves being formed at bilateral sides of said base frame respectively, each of said openings being formed at an outer sidewall of each of said guide grooves; two connecting rods each located at a front end of each of said guide grooves and each having an end pivotably mounted to said base frame for forward and backward pivoting movement; two gearboxes received in said two guide grooves respectively and each having a front end connected with the other end of each of said connecting rods for forward and backward movement externally forced to drive the pivoting movement of said connecting rods, each of said two gearboxes having a power input portions and a power output shaft, said power output shafts protruding outward out of said openings, wherein each of said opening is wider than said power output shaft to allow forward and backward motion of said power output shafts in said openings respectively; two driving mechanisms connected with said power input portions of said gearboxes respectively for providing driving power; two switches mounted to said base frame and located ahead of said two connecting rods for generating and transmitting signals while said two gearboxes are moved forward and backward to drive said two connecting rods respectively to activate said two switches respectively; two springy members each having two ends mounted to said base frame and connected with said connecting rod respectively for generating resilience keeping said gearboxes rebounding backward; two wheels connected with said two power output shafts respectively; and a control system connected with said two driving mechanisms and said two switches for controlling said two driving mechanisms and receiving the signals from said switches and further changing driving status of said two driving mechanisms.
