A system for assembling electronic devices includes at least one coating element for applying a moisture-resistant coating to surfaces of a device under assembly, or an electronic device under assembly. A sensor is disposed at the steering wheel, this sensor being adapted to detect in a contactless way data related to a driver of the vehicle. Two trucks roll on wheels each about their own elevated guide for fore-and-aft rolling of the hitch point. Microcontroller analyses input from the laser transponders and determines their output.
