The Axon-Bus system is system for transcarpal, transradial and transhumeral fittings. Axon stands for adaptive eXchange Of Neuroplacement data. The Axon-Bus itself is a new development by Ottobock for the field of exoprosthetics. It was derived from safety-related bus systems in the aviation and automotive industries and is a true innovation of our Research and Development department.

The advantage is that it constitutes an optimised, self-contained data transmission system. The individual components communicate with each other perfectly, eliminating losses in terms of data transmission, speed and functionality. This results in a plus in safety and reliability for the user. Compared to conventional systems, this is achieved by a significant reduction in sensitivity to outside interference.

In combination with the Michelangelo hand, the Axon-Bus system offers more degrees of freedom than ever before. The user benefits from enhanced hand functionality. The modular prosthesis system can be expanded with additional components in the future.
