Frequently Asked Questions — IPE Robotics (Keyi)
What reduction ratios and weight savings does the GJCS-20-II harmonic reducer offer?
The GJCS-20-II harmonic drive reducer provides reduction ratios of 50, 80 and 100. Its optimized cup-type flexspline and cross-roller bearing reduce raw alloy steel usage by 50 % and cut overall volume and weight by at least one-third (≥1/3).
Can IPE AI vision cells inspect machined parts covered in coolant or oil?
Yes. The Oil/Water-Stained Parts AI Bin-Picking Inspection cell uses deep-learning neural networks trained to distinguish oil/coolant droplet reflections from true surface defects (scratches, burrs, dents) with 100 % inspection coverage right off the CNC machine.
Public IPE Group catalogs list core kinematic parameters for robots and harmonic reducers without publishing STEP 3D CAD files or fixed price lists—these are provided per project.
