Sumo Bots

Challenge:

Background/Problem: You are to design a sumo-bot with the materials listed below to compete against other sumo-bots in a 7' diameter arena. You can fabricate your sumo-bot however you like as long as you conform to the criteria listed below. Remember to use the Engineering Design Process when solving your problem.

Engineering Design Process

1. Identify problem
2. Research ideas and solutions
3. Select the best idea
4. Test the Idea
5. Evaluate the test results

Criteria:

1. Your sumo bot can use only the materials listed in the materials list.
2. Each team must have a driver (person that controls the direction of the motors) and a person to control the voltage that the motors recreive (0-10 D.C. volts)
3. Matches will be the best out of 3. You must push the other teams sumo-bot outside the areana.
4. You may not touch yoru sumo-bot once competition begins.
5. Interfereing with the match will result in a loss for the team that does so
6. Judges ruling is final - Silvis/Amato are the jduges
7. Continuous spinning is not allowed, several spins are.
8. Once your robot becomes inactive you loose. i.e, if your motors get dis-located from your robot, your wires get disconnected, etc; judges ruling is final.

Materials:

1. 3 sheets of 8.5" X 11" plexiglass (At least 1 sheet will be used to cut wheels from)
2. 1 steel H bracket
3. 2 D.C. Motors with hubs
4. 1 wiring termianl
5. Nuts and Bolts
6. 2 wires
7. 4 rubber bands for traction - You may bring more rubberbands from home if you choose.
8. Plumbers tape to attach motors to plexiglas.

Steps for completion

1. Sketch at least three ideas
2. Pick best idea and do a paper mockup with 8.5" X 11" card stock. Locate the center point for all holes to be drilled. Remember your H bracket must mount to your body, and the 2 motors will mount to the H bracket.
3. View the PARTS WIZARD TUTORIAL BEFORE YOU COMPLETE STEP 4
4. Draw wheels in Parts Wizard DOWNLOAD HUB HOLE LOCATIONS FILE
   ***MAKE SURE YOU SAVE THE FILE TO YOUR ENGINEERING FOLDER
5. Cut Wheels on CNC machine (Silvis/Amato will help)
6. Cut body out of plexiglas (SCROLL SAW & DRILL PRESS)
7. Attach H bracket and motors
8. Solder wires to motors & attach wiring terminal
9. Test
10. Revise
