Thank you for your answer !
I still have some questions about the project :
- are there wheels that would be more adapted to a three-wheeled robot ? (one motorized wheel at the front, two wheels at the back which are not motorized, but are there only to "carry" the robot)
- we do not need the ability to turn (the robot only needs to be able to go straight forward), what can we change about the components ?
- would there be any problem about mounting the robot, especially if we use another microcontroller (that is said to be able to be used on robots) ?
