summary

A handheld controller called CLAW combines a servo motor plus force sensor and a voice coil at the fingertip to render three modes: grasping, touching, and triggering. It produces controllable stiffness up to 60 N/mm and peak forces near 30 N, switches mode by sensing thumb opposition, and runs internal loops while the whole system samples around 90 Hz. Two user studies (12 participants) show convincing grasp and trigger feedback but weaker texture and touch realism and some latency and actuator limits.
