Below the Giant Diencephalic BrainSTEM Robotics Team describes their robot design used in the FIRST Tech Challenge competition. They won 2nd place at nationals.
Final Design Iterations
When starting the process of integrating all of the subsystems, we decided to go for a modular approach – every subsystem is its own piece inside the robot’s shell. This allowed for the construction of the robot to be quite simple, and we didn’t have to worry about subsystems attaching to each other. That said, with anything that has a simplistic design, a lot of effort is put in behind the scenes.
First, we have the drivetrain. Behind the final design lies the brainstorming power. At the beginning of the season, we desired to be able to fit within the 13.7-inch space between the barriers and the wall. This drivetrain is 13 inches wide, allowing for quick, easy cycles from the warehouse to the shipping hub. The wheels on this drivetrain were tested many times, but we ultimately decided on four-inch mecanum wheels, allowing for the best multi-directional mobility for the challenge. As shown in the image, the motors are placed in the back two-thirds of the robot, allowing for an opening for the collector to sit in. Finally, the drivetrain was significantly reinforced
