A second test for lego pneumatic engine : a manipulator with rotating superstructure, lifted arm and claw. Powered by simple LPE.


The machine is powered by my own single lego pneumatic engine based on standard crankshaft and connecting rod setup. The gearbox is used to operate the 3 functions which are rotating superstructure (turntable), lifted arm (worm gear) and claw (with axle in the turntable). The engine is reliable and works smoothly, thanks to inertia wheels (8420 wheel). It runs at 200RPM with 4 pumps.
