A few words and a project written by Jack, an electrical engineer working for Control Focus.
One of my favorite projects we've had the pleasure of working on was the Farra Compact Duo BMUs. We had the chance to build two of these incredible self-contained building maintenance units. Often referred to as the window-washing cranes, these machines make looking after your skyscraper a breeze. Equipped with 4-wheel drive and 4-wheel steer, we were able to design custom steering modes that allowed them to tackle even the most complex architecture.
But don't let the intuitive control scheme fool you, this beast is more complex than Schrödinger's cat at a quantum physics convention! Months of R&D went into creating a system that flawlessly coordinates 10 motors, 10 drives, 9 sensors, a PLC, a touchscreen, and a battery system, think of it as a mechanical ballet.
Check out the photos of these impressive machines!
