Our 2018 robot could place power cubes in the switch and exchange, and climb using the hooks on the front of the elevator. Although there are two hooks, we were able to climb using only one, leaving room for our alliance partners if necessary.
We made sure to design our robot to move quickly across the field while maintaining maneuverability. We did this by having a flat wheel base using 4 powered high-grip wheels and 2 unpowered omniwheels allowing for easy turning.
We also found importance in having an effective intake to quickly and securely move cubes. We used 4 inch compliant wheels to ensure a good grip, and allowed our arms open and close to make it easier to pick up cubes.
