Robot Gripper Test Object Challenge

The mounting plate mechanism features two tubes connected by an extension spring, with the plate screwed onto an inner one and a clearance hole for holding the test object. Choosing this setup addresses issues in categorizing test objects into Shape Test Objects (STOs) and Force Test Objects (FTOs). STOs require specific geometry and shape for comparisons, and should be cheaply manufactured or purchased. Mounting plates are easy to adjust based on load calculations, spring size, and tube length. Various shapes can be used, such as Tetris blocks, D20 and D12 dice, or drop-shaped objects. These simple geometries offer various experimental possibilities while reducing complexity. Drop shapes allow for grip angle studies, unifying results for robotic arms' specifications. Suggested sizes include metric and imperial measurements. In summary, a range of easily manufactured or commercially available simple shapes best suit this mounting plate setup.
