I am a robotics enthusiast. I have previously with a team of others worked on robots that used line tracking for navigation and ping sensors(ultrasonic sensors ) to ovoid obstacles or pick some items. Thou the robots did work, the had to use a predetermined path. This means the can only be used for the purpose and place the had be designed, therefore, offering little flexibility for use. Below was a robot designed for NACOSTI robot competition ( A robotic contest held annually in Kenya during the national science week);
So, to decrease the limitations we had with the line tracking robots we decided to give our next robot vision among other enhancements. We are proposing to use a raspberry pi 3 as opposed to Atmel microcontrollers as we used before for our first prototype. Will be posting on the progress of the design and source code here.
