Abstract: The present invention discloses a pipeline patrol inspection robot having variable tracks and a control method therefor. The pipeline patrol inspection robot of the present invention includes a robot body, track assemblies symmetrically disposed on a left side and a right side of the robot body, and a movement driving mechanism. The robot body is connected to the track assemblies on the left side and the right side by track fixtures, and track angle adjusting mechanisms are respectively connected between the robot body and the track assemblies on the left side and the right side. By means of the present invention, a track camber angle can be adjusted. In addition, each track angle adjusting mechanism is independent, and has desirable flexibility to adapt to different pipeline environments.

Abstract: The present invention provides a two-degree-of-freedom rope-driven finger force feedback device. The two-degree-of-freedom rope-driven finger force feedback device includes a hand support mechanism, a thumb movement mechanism, an index finger movement mechanism, and a handle mechanism. The hand support mechanism includes a motor, a motor shaft sleeve, a sliding rail, and an inertial measurement unit (IMU) sensor. The thumb movement mechanism includes a long rotary disc, a torque sensor, an angle sensor, a thumb sleeve, a pressure sensor, two links, a thumb brace, and a thumb fixing ring. The handle mechanism includes a cylindrical handle, a pressure sensor, a flexible fixing band, and a slider. Torque is driven between the rotary disc and the motor by using a rope. The handle mechanism is movable forward and backward and is capable of automatic restoration.
