The Waitron C embodies the successful development of a completely modular service robot. With the help of the modules, the chassis can be adapted to different working conditions, as can the central transport module, which enables the combination of inserts and compartments of different sizes and shapes. Equipped with sensors and a screen, the upper module is designed for interaction with humans. The robot can recognise its surroundings or display information, among other functions. An extension at its back ensures the possibility of future changes.
