Totem BUS System

Advanced modular extension system allowing for easy plug and play robot building without limitations. Compared to other systems – Totem BUS uses more versatile communication protocol and is able to transfer more power over a single cable. RoboBoard X4 utilizes it to expand functionality, add additional sensors (like distance, line follower), making robot self aware and control various peripherals. In this way you can focus on robot building and programming, avoiding all the hassle with libraries, loose connections and incompatible electronic components.


Main advantages:

  • Easy controllable with Totem programming
  • Fast and reliable (CAN bus based)
  • Longer cable distances and higher power
  • Versatile communication protocol (peer-to-peer)
