Step 4Camera & Sensors
The main feature of the robot, at least for the project we were given, was the camera, which had to be able to look around and allowed for precise control of its movement. The solution we settled on was a simple Pan & Tilt assembly, which consists of two servos artistically glued together (hmmm) on top of which sits a very high-def camera available on eBay for around 20$ (heh...).
Our voice control allowed us to move the camera with the two axis provided by the servos. The assembly itself is mounted on top of our central "tower", combined with one servo mounted a little off-center, allowed the camera to look down and see the grippers, helping the operator with his maneuvers.
We also equipped BOTUS with 5 infrared distance sensors, mounted on the side of the central tower, allowing them a good "view" of the front and sides of the robot. The range of the front sensor is 150cm, the sensors on the sides have a range of 30cm and the diagonal ones have a range of up to 80cm.
