You can watch the final result in this short video, and see the trailer following him around the farm. In this version, the leader has to wear a red shirt to be properly tracked, but future versions can be made to track a variety of wardrobes. This project was a great learning experience, and could also be a great baseline for future cart-like robots. Do you have any ideas for expanding this design? [Théo] has already mentioned he wants more powerful motors. And if you are into this genre, check out this motorized 3000 W electric wheelbarrow we wrote about a few years ago or radio controlled electric wheelbarrow racing from 2019 (what could possibly go wrong with that?). Thanks to FabAcademy instructor [Luc Hanneuse] for sending in this tip.
