Description
Bobo Li designs a smarter controller for a hydraulic lifting arm's wrist. His engineering paper appeared in PLOS ONE in 2026. Old controllers lag and track paths loosely. That matters when a machine arm must place loads with care. His design builds the arm's physics straight into the control loop. Smart algorithms then fine-tune the loop as it runs.
Tests showed tight path control. The worst tracking error was a fraction of a millimeter. Fault spotting scored very high. Energy use stayed lean as well. The design beat several recent rivals on accuracy, steadiness, and speed. It targets smart factories, where lifting robots must be strong and exact.
