I made an FTC Drivetrain. We need to make one for my First Lego League team. This was my first basic drivetrain through Onshape. The most challenging part was trying to attach the belts on since we had to make them with a certain size to make sure they fit without glitching out the design. I am most proud of being able to add advanced features on it such as odometry on the robot. To access this project you just have to open the onshape file link and see the robot!
