This article presents a finger-mounted 4-degree-of-freedom haptic device created using origami fabrication techniques. The device is capable of providing normal, shear, and torsional haptic feedback to the fingertip, and reduces complexity and device footprint through origami manufacturing principles.
We present a finger-mounted 4-degree-of-freedom (DoF) haptic device created using origami fabrication techniques. The 4-DoF device uses a parallel kinematic mechanism and is capable of delivering normal, shear, and torsional haptic feedback to the fingertip. Traditional methods of robot fabrication are not well suited for designing small robotic devices because it is challenging and expensive to manufacture small, low-friction joints. Our device uses origami manufacturing principles to reduce complexity and device footprint. We characterize the bandwidth, workspace, and force output of the device. The capabilities of the device, particularly the torsion degree of freedom, are demonstrated in a virtual reality scenario. Our results show that the device can deliver haptic feedback in 4 DoFs with an effective operational workspace of 0.64 cm(3) with +/- 30 degrees rotation at every location. When isolated to a single Dole, the maximum force and torque the device can apply in the x-, y-, z-, and theta-directions are +/- 1.0 N, +/- 1.25 N, 1.6 N, and +/- 5 N. mm; the device has an operating bandwidth of 9 Hz.
