In 2015, the challenge was Recycle Rush, where teams of 3 robots had to work together to stack as many totes on top of each other, along with large cylindrical trash bins and pool noodles. Our design, known as The Dreadnought, was 6 1/2 feet tall and weighed over 100 pounds. It consisted of 2 CIM motors powering the 6 foot tall chain and hook system. We were able to pick up to 2 totes at a time, then in turn creating stacks of 4. We placed first in the Wilsonville tournament, but were knocked out at Oregon State. We had a very successful year and learned many things.
