US 11,630,027 B1 · Testing rigs having variable mass properties for robotic end effectors and associated methods of use

Abstract

Systems and methods to test robotic end effectors may comprise a testing rig having variable mass properties. The testing rig may include a variable weight assembly and a movement assembly that can adjust a position or orientation of the variable weight assembly. In this manner, the testing rig can be modified to simulate or replicate mass properties of a plurality of items, and grasp performance of a robotic end effector may be measured using the testing rig. Further, simulation models of end effectors and items may be validated based on actual grasp performance of a robotic end effector and the testing rig having variable mass properties.

Dependent claims

A system to test an end of arm tool (EoAT), comprising:

a testing rig, comprising:
a base plate;
at least one linear slide coupled to the base plate;
and
a weight assembly coupled to the at least one linear slide, the weight assembly configured to move relative to the base plate via the at least one linear slide;
and
a control system configured to at least:
determine an EoAT to grasp the testing rig;
determine mass properties for the testing rig;
instruct movement of the weight assembly of the testing rig based at least in part on the determined mass properties;
and
instruct the EoAT to grasp the testing rig having the determined mass properties.
