PROJECT TOPICResearch Frontiers & Advanced Kinematics
Magnetic Levitation Haptic Interface
An advanced haptics and telepresence research concept exploring Lorentz force electromagnetic levitation coils to float an operator handle in free space, providing high-bandwidth force reflections without mechanical joints.
Zero-Friction Zero-Backlash Haptic Telepresence
- ✓Achieves completely friction-free, zero-backlash force feedback with no mechanical linkage.
- ✓Delivers ultra-high haptic bandwidth capable of rendering delicate virtual surface textures.
- ✓Floats freely within a 25mm spherical workspace using coordinated Lorentz magnetic fields.
The Engineering Challenge
Problem / Objective
Traditional mechanical linkage haptic arms suffer from joint friction, inertia, and gear backlash that mask delicate tactile textures during micro-teleoperation.
