A perennial challenge when rendering a virtual surface with an impedance-type haptic interface is making the surface feel hard without destroying its realism, since simply increasing its stiffness can lead to instability. One way to increase the perceived hardness without increasing stiffness is to
In systems comprising stationary electromagnets designed for magnetic manipulation and remote magnetic actuation, the standard method for achieving some desired system output (e.g., magnetic force and torque) is to form a matrix that maps the electromagnets' electrical currents to the resulting outp
Presents corrections to the paper, “A critical analysis of eight-electromagnet manipulation systems: The role of electromagnet configuration on strength, isotropy, and access,” (Pourkand, A., et al), IEEE Robot. Autom. Lett., vol. 3, no. 4, pp. 2957– 2962, Oct. 2018.
It is known that in the creation of isotropic magnetic manipulation systems using a set of stationary electromagnets, eight electromagnets are necessary to ensure that there are no singularities in the workspace. A variety of eight-electromagnet configurations have been proposed to date. In the firs
