Mecanum Wheel platform - Arduino Mega project

Here is the presentation of the report video of my prototype class.
The project is a mecanum wheel design and uses one Arduino Mega, one USB Host Shield and two l298N bridges to control the four electric motors attached to each wheel.

If you don't want to see the building/machining process, you can jump to 11:30 or watch the final presentation on the second video

If anyone is interested, I can show more details of the project
Thanks
