This would use the camera functions and the GPIOs on the Raspberry Pi. The robotic arm would be controlled by the Pi in such a way that the user could choose an object, and then using the technology behind motion tracking, the arm would find and move the object to a new location. The possibility of voice commands could also be explored so that the only input device is the user’s voice. The technology could be useful in other applications, eg. assisting with mobility for those with disabilities.
