Abstract

The invention discloses a mechanical arm and a table tennis robot comprising the mechanical arm, and relates to the technical field of robots. The mechanical arm comprises a first drive joint, a second drive joint, a third drive joint, a fourth drive joint, a fifth drive joint and a tail end actuator, the first drive joint is connected with the second drive joint, the second drive joint is connected with the third drive joint, the third drive joint is connected with the fourth drive joint, and the fourth drive joint is connected with the fifth drive joint; and the tail end actuator is mountedon an output shaft of the fifth drive joint, each of the first drive joint, the third drive joint, the fourth drive joint, and the fifth drive joint has the rotational degree of freedom, and the second drive joint has the telescopic degree of freedom. The table tennis robot includes the mechanical arm and a linear motion module, the batting range is wide, the movement speed is high, and the batting speed is high.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a mechanical arm and a table tennis robot with the same. Background technique [0002] A table tennis robot is a robot that can play table tennis with humans. [0003] Existing table tennis robot mainly contains following two forms: 1, a five-degree-of-freedom parallel mechanical arm is fixed upside down on the table tennis table, and the end of this parallel mechanical arm is connected with a table tennis racket. 2. The table tennis robot includes a series mechanical arm with five degrees of freedom and a linear slide table parallel to the width direction of the table tennis table. The mechanical arm can move linearly along the width direction of the table tennis table. [0004] Generally speaking, in the case of the same specifications, the movement space of parallel robotic arms is much smaller than that of serial robotic arms, so the range of motion of the first type of table...
