The invention belongs to the technical field of robots, and particularly relates to a robot angle ball bounce detection mechanism. The robot angle ball bounce detection mechanism comprises a detection component, a bounce ground, a launching component, a base component and a control component, wherein the bounce ground is positioned between the detection component and the base component, the control component and the launching component are positioned on the base component, and the detection component is provided with a speedometer. The mechanism is characterized in that according to the robot angle ball bounce detection mechanism, the base component is used for supporting other assemblies of the mechanism; the launching component is fixed to the base component and used for launching angle balls; the detection component is used for detecting the velocities of the angle balls before and after bounce; the control component is used for controlling the action of the whole mechanism. Therefore, the mechanism has the advantages of simple structure, high control precision, low cost and light weight.
