I haven't seen this much chain since Chainzilla.

[RyanShoff]

About 50 feet of chain. None in the drivetrain.

What thought process led you to choose three separate fork systems instead of one?

[Kevin Leonard]

Yo this robot was so dope to watch in action. So intelligently engineered, and so complex.
Watching you upset the #1 seed at your second regional with smart teamwork was also a treat.

I found this bot particularly interesting when I first saw it. In IN Districts, there is a robot that is similar, but they tilt back and load 3 totes from the Human Player station. That team is 3947. I knew the "individual tote care" would work for HP but it was cool to see 4143 work in the Landfill like it did. To say the least, it was a cool robot to see. It wasn't the fastest at the Landfill but it definitely was good at be stable and efficient.

This robot was originally designed to lift 2 totes side by side from the handles. It had 4 bars with 2 handle hooks each. The plan was to make two 4 stacks at a time from the landfill. It was actually bagged like that. We made two robots. In after bag-day driver practice, we decided it was too difficult to hook two totes at the same time from the handles consistently.

So our thought process was: How can we fix this thing? We prototyped the forks and immediately saw the potential. We kept on iterating and eventually ended up with a pretty sound robot.

Interesting note: both of these robots will be competing side-by-side at http://www.gatewayroboticschallenge.com
