Experimenting potential configurations for a mechanical arm. Motor + screw as actuator. To do: – Stop motor when the clamp grabs something (without crushing it) – Add servos for 2 axis movement The planned steps for this project actually are: – Define platform – Locate the object – Move towards it – Collect – Sort… Read More »
We held our first line following competition last week. We knew ahead of time that right angle turns may cause some issues, so we set up a few to see what happens. We did have some challenges, like you can see here: But at the end we had several clean runs and a winner:
A few days ago we got several ATTiny85 ICs (datasheet) and this is a first video of the small chip in action. Working out the kinks of programming this little guy with an Arduino Uno and getting Arduino libraries to work with it takes a bit of effort and digging around the forums. Still, as… Read More »
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… Read More »
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… Read More »
Turns out that rechargeable batteries and the L293D motor controller really slowed things down. Added another battery pack, and with 12 volts the bot actually moves. No smoke coming out of the motors, so all is well….
Here i tested my bread boarded tank against a simulation of the trial.
