This letter presents a method enabling intuitive physical human-robot interaction (pHRI) with flexible robots using an end-point sensing device. The device is a passive serial chain of encoders and lightweight links, mounted in parallel with the manipulator. By measuring the deflection of the end-effector relative to the base, the whole body of the manipulator becomes a potential interaction inter...Show More
This article presents the design of a noncollocated feedback system for flexible serial manipulators. The device is a passive serial chain of encoders and lightweight links, mounted in parallel with the manipulator. This measuring arm effectively decouples the manipulator's proprioception from its actuators by providing information on the actual end effector pose, accounting for both joint and lin...Show More
This article presents two distinct manoeuvres allowing an articulated robot in free fall to change its orientation using closed paths in the joint space. It is shown through dynamics simulations that the magnitude of the net rotation is dependent upon the amplitude of the angular displacement of the joints. With realistic joint limitations, the robot, which includes rotary actuators only, can perf...Show More
