This utility model discloses a backpack-type space-assisted training robotic arm, specifically relating to the field of robotic arm technology. It includes a carrying strap, an upper robotic arm, a front robotic arm body, and a hand end effector device. The carrying strap is connected to the upper robotic arm, and the upper robotic arm is connected to the front robotic arm body. The front robotic arm body also preferably has a hand end effector device at its front end. These four parts are interconnected via various telescopic shafts, and wiring is provided according to the connections of each part. This utility model employs an optimized backpack-type space-assisted training robotic arm to simulate the motion states of different masses and the interaction forces between the astronaut and the spacecraft in a simulated space operation environment on the ground. This achieves virtual operation training and a sense of presence for astronauts in a simulated microgravity environment, helping them learn how to operate objects of different masses and avoiding collisions due to operational errors.
