MECANT is a fully independent hydraulic six-legged walking machine. The machine weighs about 1100 kg and is driven by a 38 kW 2-cylinder ultra-light aeroplane engine with air cooling. The leg mechanism is a 2-dimensional pantograph with vertical rotation axis thus having 3 d.o.fs and they are drived by hydraulic system. The operator controls the vehicle remotely by the joysticks via the radio link.

The control system consists of a computer network connecting seven on-board computers running under a commercial real-time operating system (QNX), sensors for the vehicle body and legs, and a portable operator interface with the radio control and communication facilities.

Today MECANT is already retaired. Its successor is WorkPartner., which is a light weight service robot. WorkPartner is moving by the aid of a four legged hybrid mobility system.
