BitFoot: Foot pressure sensor for a humanoid robot
This board measures 4 differential voltage signals from load cells. It connects to a RS485 or TTL Bus compatible with Dynamixel motors from Robotis.
We managed to achieve a sensor update rate of 697Hz. The board itself can be read faster than 1kHz from the Dynamixel bus.
