Method for determining security and feasibility of instruction of mobile robot

The invention discloses a method for determining the security and feasibility of an instruction of a mobile robot. The method comprises the following steps: with the robot as an origin A of a coordinate system, acquiring coordinates of others in a direction of an instruction sent by an authorizer; selecting a person of others, who is closest to the authorizer, and calculating an included angle theta between a connecting line of coordinates C of the person who is closest to the authorizer and the origin and a connecting line of coordinates B of the authorizer and the origin; calculating a protecting angel alpha of the authorizer and a protecting angle beta of the person who is closest to the authorizer; when the angle phi of the direction of the instruction sent by the authorizer satisfies a preset safety condition, determining that the instruction provided by the authorizer is safe and feasible. According to the method disclosed by the invention, active avoidance of others in a path of robot instruction execution can be avoided, the possibility of touching pedestrians who carry bulky goods when the robot moves can be avoided, the safety performance of the robot is increased, and the intelligence level of the robot is improved.
