Kinematics, Navigation, and Path Planning of Hexapod Robot

In Chap. 3, fundamental analysis on COMET-IV’s leg kinematics and dynamics has been briefly discussed. On further research progress on this robot, the developed kinematics and dynamics are exploited to be used for end-effector force on foot detection and overall COMET-IV stability for force-attitude control purposes. In COMET-IV research progress, the total force on foot is calculated for center of mass (CoM) identification as an input for robot attitude during walking session. This method is based on shoulder coordination system (SCS) kinematics on vertical position and total of force on foot for each touching leg on the ground. On the other hand, the designed force delivery on foot value is categorized phase by phase and threshold sensing method is applied for dynamic trajectory walking named force threshold-based trajectory. This method is done to achieve the novel end-effector force sensorless method that is applicable for large-scale legged robot that required expensive sensor on each leg’s tip.
