Test #3 of my Arduino Uno controlled line following bot for the upcoming competition. This test was focused on checking how the bot handles 90 degree turns with sharp corners, line intersections and line breaks. The robot uses 6 TCRT5000 IR reflector sensors positioned in a line. ...
This is a very basic line following robot using 4 IR led sensor receiver pairs in a line, continuous rotation servos and Arduino Uno. The wheels are made from beer coasters and I was planning to add a wheel encoder using another IR led / sensor pair at a later stage. The logic is very simple, but works well to test the line detection and the basic movement commands. The next step should be applying a better control mechanism, maybe PID? ...
General Objectives: The objective of this contest is for a robot to follow a black line on a white background, without losing the line while navigating several turns on a race course. The robot to complete the course in the shortest period of time while accurately tracking the line from start to finish wins. ...
Release Candidate Very hard to keep it steady as voltage increases. That’s the best speed/stability result I got so far. Now using 3 sensors. The video below has it running at about 6V. Test 1 With differential steering This is the project in a very early stage with a regular RC toy steering mechanism. Using 2 IR sensors to detect change in color and correct direction. It’s pretty rough right now and it overshoots all the time. Not the best hardware… No word about software (don’t want to blame myself 🙂 ) Bare steering logic (RC toy version) ...
