From March 9 - 23, the team updated the CAD models according to the first prototype testing. After the test, there were some flaws in the 3D printed materials that made accessibility an issue. For example, the screw holes where the box fit onto the top of the robot made it hard to mount. This made assembly a challenge and also certain materials hard to reach. To mitigate this, there are holes cut into the box to ensure they can reach for the next test. The team has already submitted the final iteration to test. The parts are currently being printed by the stakeholders’ technicians. Finally, because the motor spins at a high rate, the team is utilizing a stopper to ensure the arm attachment stops at a 90 degree angle from the floor. The developer assembly has also been updated to fit a motor instead of fan, which will allow greater torque output. The team plans to have the final iteration of prints by the end of next week. Afterwards, they will focus on refining the material
