Abstract

A novel tribrachiation robot is designed to enhance its cross-obstacle ability

simplify its structure

and reduce the load on motors. A dual-parallelogram frame structure is taken as the main part of the robot to adjust the gesture of each arm

the robot centroid can be adjusted to decrease the load on the motors for frame shape control

and the robot ability to traverse flexible jumper line is enhanced by the gripper at the end of each arm. Line inspection robot

which can be categorized as a floating base robot

will rotate around the line passively due to centroid deviation when it changes configuration to traverse obstacles. The kinematic analysis for floating base robot is converted to one-dimensional optimization

where the gravity balance condition is considered to construct the optimization objective function and the floating base angle is regarded as the optimization parameter. Simulation shows the effectiveness of the proposed method

and the feasibility of the mechanism is verified by the prototype robot traversing obstacles on line in laboratory environment.
