Identification and Optimization of the Haptic Rendering from a “Novint Falcon”. Aman Shah Scott Teuscher Advised by: Prof. Jake Abbott, Dept. of Mechanical Engineering.
Overview • Novint Falcon is low cost high volume haptic interface • Haptic performance varies within and from device to device
Motivation • By increasing the haptic performance of the falcon we can get consistent and similar feel to more expensive “precision” devices • Example: 2 orders of magnitude in cost • Force Dimension Omega.x ~ $20k • Novint Falcon ~ $150
CHALLENGES • Kinematics • Accurate System Identification • Weights and dimensions • Center of Mass • Moments of Inertia • Motor Characterization • Model Predictive Control MOMENT OF INERTIA INSTRUMENTS - XR Series
QUESTION WE HOPE TO ANSWER : Can we develop an algorithm for gravity and friction compensation to cause the Novint Falcon to feel consistent within it’s own workspace, as well as between different devices?
FINAL OUTPUT • User tests to determine if we have increased the haptic performance within and between devices • System parameters for general public use • Barring no improvement, an algorithm for improving the haptic performance of a Novint Falcon
