The drive system is basically done, except for properly attatching the wheel treads (bye bye zip-ties), and putting in the pneumatic shifter for the gearboxes.
The box pick-up/lift system also needs to be attatched. We completed it today, but we are waiting for a cylinder to arrive (should tomorrow) to mount it to the bot. When the lift system is folded down, we fit under the 14" bar.
Some other electrical components, coverings, team numbers, sponsors, etc still need to be put on as well.
its a 2 motor 2 speed transmission… and it is SWEEEEEET! … good ol canadian engineering… which myself, my friend lewis, and our teacher designed… lets just say in high gear it can pull someone who weighs like 200 lbs… i can only imagine what it can do in low… muahaha
Very nice gearbox and drivetrain. This is a robust design which is very well laid out with large bearings. I really like how the drill motor is simply an input device, and if FIRST would change that motor next year, it won’t change your design much.
Also, nice use of extrusions to the benefit to get your chain tension to your front and back wheels… the most efficient way to do a 4 wheel drive.
One question: How do you switch gears? Is that device hidden, or just not installed yet?
nice tranny… if you guys ever have weight trouble, though, those bearings on the transmission could definitly br less bulky… i think we use those in our rookie year and they can get weighty and excess… but nice manufacturing
