Abstract: A collision sensor, including a hollow housing having an accommodation space; a collision information generator arranged in the space and adapted to produce an output indicating a directional and/or positioning information of the collision when being triggered during the collision; a collision detecting member arranged over and adapted to trigger the collision information generator upon being driven by the obstacle during the collision; wherein the collision detecting member and the collision information generator are spaced apart from or in contact with each other by one or more resilient members, by which the collision detecting member is switchable between a normal position at which the collision detecting member is spaced apart from the collision information generator, and a working position at which at least a portion of the collision detecting member trigger the collision information generator by a compressive/collision force from the obstacle during the collision.
