Sunday Meeting: January 8th, 2017

Upon further viewing of the rules overnight we discovered that if an opposing team’s robot touches you while your robot is in contact with the rope it is considered a foul and you are given the 50 match points as if you had climbed the rope and touched the pad. This foul is counted regardless of which robot initiates contact and therefore can be strategically used to our advantage during competition.

Small groups from yesterday shared out their diagrams and ideas for mechanisms on the robot. Most groups focused on a mechanism to hold and place gears on the peg. Some groups drew a mechanism that would pull up to the peg with the gear held vertically while other robot designs drove up to the peg and placed the gear on it horizontally and the gear would then flip down onto the peg. However, our team wants to be able to do more than just move gears; some groups sketched robots that would pick up balls from the field and store them until we’re ready to shoot them into the high or low goal. Gear, ball, and rope mechanisms on our robot must take up as little space all possible in order to fit everything into the frame.

Sharing Mechanism Ideas

Inspired by a ‘Robot in 3 Days’ video, a small group of fabricators and mentors created a wench system that may enable our robot to climb! It spins the rope inward and can currently pick last year’s robot up off the ground. Another group of fabricators began to build a return loading station and should be done with that within a few days. This will allow the drive team to practice sliding gears and balls down the chute to the robot.

The rest of the team worked on building 2 cardboard boxes using the dimension limit on how big our robot is allowed to be. By competition, our robot will need to be able to fit in one box or the other. By physically making these boxes the team can have a visual idea of how big or small we need to make things. Smaller groups also used cardboard to display their ideas for mechanisms in a 3-dimensional way.

This year’s game manual listed some new rules that will make the game even more challenging. We are not allowed to have extensions outside of our robot frame, so we will not be able to make an arm to push the touch pad on the rope. The maximum weight the robot can be now includes the weight of the car battery, so anything else on our robot cannot collectively weigh more than 100lbs. Another challenge this year will be vision. If our team is placed in station 2 for driving we will not be able to see around the airship very much, so our robot will need to have a camera on it and be able to communicate with the drive team with the limited bandwidth we are allotted.

By the end of this week our goal is to have 2 working sleds, which are basic robots without any mechanisms, and 2 working drive stations to go along with them. This way the returning drive team members can teach new members how to drive and hold tryouts later this season.

At the end of the meeting, Ozone alumni came back to Orange High School to answer questions and talk about their experiences at The Ohio State University. They offered insightful advice regarding internships, scholarships and what it’s like to be an engineering major.
