Battle-Bot Unit

Design Brief

Using the design process, you are to design and construct a vehicle that is powered by two DC motors. This vehicle must be able to follow a slalom course and fit through an opening to enter the fighting arena. Once in the arena, your vehicle has to be capable of disabling your opponent or capable of pushing it out of the arena. As with any design project, you have certain limitations.

Timeline of Project Completion (To be determined by the instructor and class together.)1. Sketch of battle bot and weapon 1day2. Research for paper 1day3. Drawings (details, assembly, presentation) 1 week details4. Construction of Battle bot body and weapon 1 week5. Testing6. Battle7. Finish Papers and drawings

Limitations of the Battle Bot

1. The body cannot exceed 6 inches wide, 6 inches high, and 6 long. This includes the weapon

2. The body of your vehicle can be made of any material that is not hazardous to the class or will damage the car.

3. Speed will be controlled by gear ratios, wheel diameter, and weights. 4. The weapon must be safe to the operator and all spectators. The weapon must

also concur with school policy. A rotating or spinning weapon cannot be used.5. The weapon must be approved by the instructor. 6. Two (2) DC motors will be given to each team to use for the battle bot. 7. A weight limit will not be enforced but the car must be able to drive without

burning out the motors. (Only one set of motors for the competition. Use them wisely).

8. No magnetic, electrical, laser, chemical, radio jamming, or microwave weapons are permitted. The weapon may not damage the other battle bot in any way.

9. Staying within the steps of the design process, both the body and the weapon must be approved by the instructor before drawings and construction begins.

Arena Requirements and Battle Rules

1. An 4ft.. square area will be used for the battle arena. 2. Each competitor must be able to fit through a specified shape (size to be

determined) and complete a slalom course before the battle. This will test driving and maneuvering skills

3. Once in the arena there will 3 rounds 2 minutes each (2 out of 3 wins). To win a round a competitor must push an opponent out of the arena or disable the battle bot so that it can no longer move. The winner of the best 2 out of 3 will advance to the next round.

4. The class and instructor will vote for winners of each round if no car has been disabled or pushed out of the arena.

Research and Information

1. Search the web for sites that explain about gears, gear ratios, kinds of gears and how they work. (A great site is www.howstuffworks.com) find more

2. Search the web for sites that explain about DC motors. Try to find the specs on the motors we are using on the mini maulers. (Voltage, amps rpm etc…)

3. Research other battle bots on the web along with weapon designs that will work for the cars we are building.

4. Take a look at electrical schematics about our car if available.

Drawing Requirements1. Sketch of your idea for the body, servo mount, and weapon.2. Individual drawings of the car chassis, servos and mount, body, and weapon

fully dimensioned on Inventor 9.3. Assembly drawing of all parts with balloons showing each part.4. Presentation file with animation showing all the parts being put together.

Grading Requirements For Each Student1. Typed written paper with all of the results of the Internet searches you conducted.

This should include all web sites and information you found in the Research and Information section above. Include all the steps of the design process in your paper and explain what you did in each step. [50 points]

2. Product Design Rubric 9 parts with grades 1-4 in each category.

____________________________________________Total [100 points]

Grading Requirements of the Team

1. Car design is functional and works and fits through opening to arena. [45 points]2. Slalom course completed [20 points] Points will be deducted per error on the

course. (ie. Crossing the centerline of road, incorrect stop, going the wrong direction on turns, etc.)

3. Weapon design is functional [35 points]4. Extra points will be awarded in the tournament for:

a. [2 points] per win in the winners bracketb. [1 point] per win in the losers bracketc. [4 points] awarded to the final champion d. [1 points awarded to the runner up.

Paper

Use the following format for your paper. Type written, double spaced normal font and size. Document your information in a clear and concise manner.

Title Page with Name and Project1. Introduction2. Research and Information (including gears and gear ratios, dc motors, weapon

design, and electrical schematics and how they work.

3. Use the Design Process given and write in detail about each section on information pertaining to your battle bot. 9 Steps.

4. Conclusion (Explaining what you have learned from the project and what we could do as a team to improve the project. Any other information or opinions you have would be great.)

5. Attach a copy of all detail and assembly drawing with a bill of materials list.
