BOTUS Project

Step 7 But... how do we control the thing?

This is where the "official" part of the term project kicks in. Unfortunately, because the various modules we used to filter our voice and convert them into voice commands were designed by Universite de Sherbrooke, I won't be able to describe them with many details.

However, I can tell you that we treat the voice through a series of filter, which allow a FPGA to recognize, depending on the state of every output our filters give, which phoneme was pronounced by the operator.

From then on, our computer engineering students designed a graphical interface which shows all of the information gathered by the robot, including the live video feed. (This code isn't included, unfortunately)

These information are transmitted through the XBee module on the Colibri 101, which are then received by another XBee module, which then goes through a Serial-to-USB converter (plans for this board are also included in the .rar file) and are then received by the program.

The operator uses a regular Gamepad to transmit the movement/gripper commands to the robot, and a headset to control the camera.

Here's an example of the robot in action:
