The invention relates to a collision position sensing method based on a six-dimensional force sensor. The collision position sensing method includes the following steps that the six-dimensional force sensor is installed between a first joint of a mechanical arm and a base; force and moment information fed back by the six-dimensional force sensor are substituted into a force analysis total equation containing gravity compensation and dynamics compensation, and acting force and moment of a collision point are obtained; and the position of the collision point in a base coordinate system can be obtained according to the acting force and the moment of the collision point. By means of the collision position sensing method, calculation of position information of point contact on the mechanical arm can be rapidly, conveniently and accurately achieved, and a robot has a higher adaptive capacity to environments.
