Vision systems are one of the more useful, albeit trickier, sensors that can be used in a robotics system. They allow a microcontroller to literally ‘see’ an object, its color, shape, and (in some cases) the material it is made from. They are used extensively almost anywhere an automated system needs to make a decision based on an object’s visual properties.
Fortunately, MindSensor’s NXTCam combined with Xander’s driver suite allows NXT users to quickly and easily program a vision system for their robots. ROBOTC forum member alain has recently created one of the basic NXTCam robots (a robot that will track a colored ball with relatively high accuracy) and was kind enough to share his programming journey on the ROBOTC forum and the video below.
If you’re interested in building your own color-tracking robot or have other, unique ideas for an NXT cam with ROBOTC, be sure to check out the Robotics Academy demo video for ideas on how the NXTCam can be used and the ROBOTC forum for coding help.
