Robotics Patent Classification
Robot hardware classifies in B25J: manipulators, robot arms, grippers, mobile robots and the mechanical side of automation. Industrial robot patents from the large Asian electronics and automation filers dominate this subclass.
The control layer, programmable logic, adaptive and numerical control, sits in G05B. Robots that learn add the machine-learning codes of G06N.
