The utility model discloses an intelligent robot's collision induction system, set up circuit, crash sensor, speedtransmitter, display circuit, warning circuit and power supply circuit including microcontroller, acceleration, crash sensor includes collision switch and acceleration sensor, and whether the information of opening and shutting that can be through collision switch and the change of acceleration determine intelligent robot and bump to the direction that intelligent robot bumped and the high position of collision reach. Simultaneously, can respond immediately when intelligent robot bumps, make intelligent robot deal with unexpected barrier better.
