High accuracy walking motion trajectory generation profile based on 6-5-6-PSPB polynomial segment with polynomial blend

Many robots, such as humanoid robot, biped robot, and robotic exoskeleton, need human guide. Particularly, there is a strong need for devices to assist individuals who lost limb function due to illnesses or injuries. Thus, several methods of generating walking motion have been implemented in order t...
