The Outer Walls
The Outer Walls
Originally just to increase rigidity and make it so the spike prime hub was no longer structurally integral, it quickly grew into a larger project involving cable guides to avoid cables tangling in the wheel and outer walls to help alignment while also having the bonus of higher visual appeal.
The Wheels
The Wheels
Our centered drive wheels cause the robot to turn around it's center by default, allowing for more precise movement. The 4 support rollers ensure the robot stays flat, and also keep you going in the right direction
Attachment Mechanism
Attachment Mechanism
Our drop-in attachment system with a locking design. It allows for fast attachment switches and is designed to complete missions the arm cannot.
The Arm
The Arm
Our precision arm, geared down 9:1, that can complete most missions. It has a unique string design to pick up the brush that is part of mission 1.
Corner Rims
Corner Rims
Our corner rims keep our robot level and precise by reducing drifting as it drives.
Attachments
Attachments
This is our gear attachment for the angler artifacts mission. It conects to the axle at the front of the robot.
This is our flag dropping attachment to put the flag below the ship. it connects the same way as the gear attachment.
This is our map clearer attachment that attaches on the back of our robot and backs up to clears the map.
This is our fork attachment it attaches to the arm so it make the end of our arm a bit thicker if needed and it helps picking up the milestone and top soil
This is our silo slammer attachment, activated by the robot when it leaves home. It hits the silo and immediately after falls off the field.

Mission Strategy Planning Table
Mission Strategy Planning Table
Book1 (1).xlsxThe above document shows how we chose which missions would be done first and what has the highest priority based on a combination of difficulty, time to complete (in a 2:30 min run), and the number of points scored.
How We Got Here
How We Got Here
Our First Designs
Our First Designs
Hungry
Hungry
Our chosen robot, missing the casing and removable hub feature at the time. Had off-center wheels and used ball bearings instead of rims and a simple arm.
Cheepie
Cheepie
A well designed small and simple robot with a great attachment mechanism. It was called Cheepie because it looked somewhat like a jeep. It started similarly to Jeffrey, but had normal black wheels and had a lot more added on over time.
Jeffrey
Jeffrey
A robot designed to test wheels, the giant blue wheels were covered with black rubber tank treads. These tank treads decreased precision but increased grip and traction.
What We Found Out
What We Found Out
Wheels
Wheels
The blue wheels often tracked dust that created imprecisions, so we tested adding tank treads over the edges of the wheels, using rubber bands to secure it. We found that this increased grip and traction but lowered precision and predictability, causing us not to use these wheels.
How We Improved
How We Improved
Gears and Rims
Gears and Rims
We upgraded the robot by adding a gear ratio of 9:1 so it was more accurate and steady. Additionally, we also decided to use rims instead of ball bearings so the robot would drift less as it drives. This also made the robot more level. The attachment on the wheel was meant to complete the market wares mission, but was not used
Outer walls
Outer walls
the walls were originally a structural project to relieve the HUB as a structural component. we used some funky pieces on the bottom to attempt to do this, but these attempts were too wobbly and finnicky due to the nature of the peices we were using.
as it was too wobbly, we added more structure in some rudimentary outer walls. it slowly gained more functionality over time, as in cable guides to keep them from getting tangled in the wheels and flat edges for alignment.
