Dynamic transition motion from ladder climbing to brachiation for a multi-locomotion robot

This paper describes a dynamic transition motion from ladder climbing to brachiation for a multi-locomotion robot (MLR). In our previous works, the static transition motion from ladder climbing to barchiation has been developed. However, the motion is based on stable static model. It is difficult to realize the flexible and fast movement. To solve these problems, a new dynamic transition motion is proposed to simplify the action steps and increase the motion speed. The gravity is used to adjust the speed of turning body motion when the left hand and left foot are considered, and a pendulum model is used in the motion planning for the MLR to catch the second horizontal bar. The motion step is simplified and the motion speed is increased significantly by using the proposed method. The simulation result is realized by using the open dynamic engine (ODE) software.
