For our 6th season, Team 5406 was set to compete at the Ryerson University event and the McMaster University event with our robot, Mo. This was our most ambitious robot to date. With more attention to quality control and precision than any of our previous robots, it was reliable and consistent throughout testing. Mo featured a significant number of laser cut, CNC routered, and 3D printed parts - all made in house. It used computer vision tracking and could efficiently complete autonomous tasks. Unfortunately, due to COVID-19, the 2020 competitive season was cut short, and Mo never had a chance to compete.
Infinite Recharge is the name of the 2020 FIRST Robotics Competition (FRC) challenge. The game involves two alliances of three teams each competing to perform various tasks. The main goal is to shoot foam balls ("Power Cells") into inner and outer goals. Score enough Power Cells, and the "Shield Generator" in the middle of the field activates. Other tasks include manipulating a spinning disc known as the "Control Panel", and returning to the Shield Generator to park or climb at the end of the match. More information can be found on Wikipedia.
More information on each of Mo's subsystems can be found in Meet the Robot.

Mo was named after a similar-looking robot from the movie WALL-E®, specifically because of a similar intake and ability to pick up items from the ground. Our practice bot, Pat, was named after the hammer from Handy Manny®.
The only parts of the robot that was not made in-house were the bumper frames, which were waterjetted and bent on a CNC brake at one of our sponsors. Without a CNC brake, it would have been extremely difficult to achieve the precise bends we wanted for our bumper frames.
This season, we faced an interesting problem — how to machine box tubing. This was a significant challenge for us on the router, but we developed a procedure where we could align, probe, and flip the tubing to get matching holes (e.g. for bearings) on both sides.
This year, we set a goal to have zero on-field breakdowns. Here's what we learned from past years in order to try to reach our goal:
