1. The document describes the final report for a robotics design project. It summarizes the problem definition, design evolution, robot operation, fabrication methods, design analysis, technical analysis, and results from robot testing competitions. 2. It discusses two robot designs created by a student team to pick up and dump balls, and the operation of these designs. Fabrication methods included building custom parts in Solidworks. 3. The technical analysis identifies elements that worked well and problems encountered, such as the solenoid being too weak. While performance was disappointing, the pickup mechanism was effective and the greatest design strength.

- 4. MCCMONROECOMMUNITYCOLLEGE Problem Definition Initial problem (robot testing 1and 2) - Task assigning. - To come up with a design. - To program the design . - To test and correct all faults so the robot can pick and dump 3 balls. - Then build the final design
- 6. MCCMONROECOMMUNITYCOLLEGE Robot Operation Both designs were based of the same pick up mechanism
- 7. MCCMONROECOMMUNITYCOLLEGE -- The first design had a carriage built to hold three balls while The second stored the 12 balls in a tube that is bent at an angle to let the ball freely roll into the box .

- 17. MCCMONROECOMMUNITYCOLLEGE Team Dynamics Question (a) -We were understanding and respectful of each others ideas - (Anthony) the project manager. - I mostly worked on the hardware while - Marcus worked on the soft wear. Question (b) -Building and assembling of base parts - Ideas of new parts - Designing of custom parts solidworks (Anthony) - Building of custom parts - Final assembly and correction of Faults Question (c) -The most difficult task was coming up and building the custom parts for it to be able to perform the task.
- 18. MCCMONROECOMMUNITYCOLLEGE Technical Analysis What didn’t work? • Ball-transfer system • Big, heavy • Solenoid was too weak • Difficult to adjust • lack Distance sensors • Unreliable, too much power consumption What worked? • The initial program • Multiple motors with same dimensions -> don’t have to redesign motor brackets • The dump mechanism

- 24. MCCMONROECOMMUNITYCOLLEGE Project Assessment Performance - The performance of robot was very disappointing compared to the others during the performance in class and during the competition Cost -The batteries added significantly to the cost since we had to get many for the trials . Sustainability - The PVC tubing which was used to transfer the ball from the conveyor to the box had the greatest carbon foot print. - Compared to the other materials this had a low carbon foot print the pvc tubing could be our best pick and to the fact that it was it was at our reach to no extra cause
- 25. MCCMONROECOMMUNITYCOLLEGE Design Features The greatest strength of our design was the pic up mechanism it didn’t fail to picked up the balls nicely. No changes could really improve the design because it was thought off thoroughly, except it is another design which can take about 2 weeks to be fully functional.
