Captured Dynamics Data of 5 Mechanical Knobs

Torque models are presented for five mechanical knobs that were characterized using the rotary haptic camera shown Figure 1. Non-linear least squares fitting was used to estimate model parameters for position, velocity, and acceleration model parts. Additionally, two simulated knobs were mod-eled to test the accuracy of the characterization algorithm. A haptic camera does for touch what a typical photographic camera does for vision. A typical visual camera measures the environment to build an image consisting of a 2D grid of coloured pixels. Likewise, a haptic camera Figure 1: Rotary Haptic Camera Apparatus
