Researchers at Carnegie Mellon University are experimenting with a haptic interface that does not depend on actuated linkage or cable units. As a substitute, their interface makes use of a strong electromagnet to levitate a handle that appears a bit like a joystick. The consumer manipulates the levitated instrument handle to work together with computed environments. As she moves and rotates the handle, she will be able to feel the motion, site (www.zilahy.info) shape, resistance and floor texture of simulated objects. This is one in every of the large advantages of a levitation-primarily based technology: It reduces friction and other interference so the person experiences less distraction and remains immersed in the virtual surroundings. It additionally permits constrained motion in six degrees of freedom (compared to the entry-level Phantom interface, which solely allows for three active degrees of freedom). The one drawback of the magnetic levitation haptic interface is its footprint. An entire cabinet is required to house the maglev machine, power provides, amplifiers and management processors. The consumer handle protrudes from a bowl embedded in the cabinet high.

Sufficient battle stories from the sewer bot. Let’s move on to a battlefield you’ll be able to relate to: your bathroom.
