BABY BAJA - The Baby Baja Rally is a competition that challenges middle and high school students individually or as a team to build a miniature all-terrain vehicle capable of traversing sand dunes, water, and logs. This competition is intended to reward imagination, ingenuity, and teamwork.
OBJECTIVE
The ODU Baby Baja Rally is a competition that challenges middle and high school students individually or as a team to build a miniature all-terrain vehicle capable of traversing sand dunes, water, and logs (1-inch diameter dowels). This competition is intended to reward imagination, ingenuity, and teamwork.
DESCRIPTION
The car should typically be small, no more than 12" in length, with 3 or 4 wheels, 1 or 2 of which are powered by the motor. No steering is needed. Remote controls are not allowed. The track will have an upward high coefficient friction slope of about 20 degrees. About 8 dowels of 1" diameter spread 1" apart will be immersed in partial sand on the flat part of the track. The vehicle needs to also overcome a downward slope of about 45 degrees followed by a 20" long sand/water dune of 1" in depth. The total length of the track is about 152".
CONTEST RULES
- 1. Energy and power supplies will be limited to one (1) Radio Shack 1.5-3.0 volt DC motor (Part # 273223) and two (2) Radio Shack AA batteries (Part # 23-557). You may also use a gear box from radio shack.
- Absolutely NO commercial model kits, pre-assembled vehicles, or portions of model kits or pre-assembled vehicles will be allowed (accept for wheels, but more points are rewarded for making your own.)
- ORIGINALITY is the most heavily weighted judging criteria. Points will be given for creative use of common household items.
- Must be built before arriving to the college, (minor fixes/ repairs are all right prior to competing.)
- MUST HAVE 4 wheels capable of going thought sand/ dirt and raises the body off the ground at least 2- 2.5 inches or more.
- No additional energy sources are permitted in giving power to the wheels. The motor may not be taken apart or altered in any way.
- The contest allows for two (2) runs, and the best time will be taken. (Remember that time is only 15% of the scoring.)
- The entire vehicle should cross the finish line, without breaking apart, in order to score the 5% listed below for finishing the course. However, in the event the car does not cross the finish line, and/or breaks apart, the judges may award some performance points depending on distance traveled and the degree to which car remains intact.
- All decisions of the judges are final.
Suggestions:
- Baja is big about Suspension, so a baby Baja……*hint hint*
- Test run your baby Baja at home in a sand box or on rough terrain
- read up about torque and apply it to your design
- Make your wheels with something that has friction
- Be creative!
JUDGING
- Mechanical design:
- Chassis design 10%
- Originality 30%
- Performance:
- Finishing the course 5%
- Time 15%
- Stability 10%
- Physical properties:

RUBE GOLDBERG MACHINE CONTEST
A Rube Goldberg machine is a complex device that humorously performs a simple task in an indirect manner. A more complete definition of a Rube Goldberg machine, background, and how to build a Rube Goldberg machine can be found at: http://www.anl.gov/Careers/Education/rube/rube.html
Additional information can be found at:
http://www.rube-goldberg.com/
This commercial for Honda is a fantastic example of a Rube Goldberg machine. http://www.youtube.com/?v=ZwwWtbMfEFE
The rules for the Rube Goldberg Contest are listed below.
- The final task the machine must complete is pouring a 8-oz. Styrofoam cup of water (half-full) into a contained placed 4 inches below the bottom of the cup.
- The machine must be no larger than 6 ft x 6 ft x 6ft.
- The machine must have a minimum of ten (10) steps. There is no maximum number
of steps.
- The machine must run for no more than one (1) minute per run.

MODEL SPAN BRIDGE - The object of this contest is to construct a 12-inch-long model bridge from a given amount of balsa wood. This model will be tested to destruction to determine its load-carrying capacity as related to its weight when subjected to a single loading
OBJECTIVE
The object of this contest is to construct a 12-inch long model bridge from a given amount of balsa wood. This model will be tested to destruction to determine its load-carrying capacity as related to its weight when subjected to a single loading. There will be separate competitions for high schools and middle schools.
GENERAL RULES
All contestants must use the official material kits available from the department of Engineering and Technology at Old Dominion University. The cost of the kits is $4.00. Kits are to be picked up from the Engineering Technology Department at Old Dominion University, Room 214, Kaufman Hall, 683-3765.
- Only one materials kit may be used to construct each model.
- The wood cannot be treated or painted in any way. Such treatment would alter the strength characteristics of the wood.
- The model must be completely assembled when submitted for testing.
- The panel of judges will determine the final decision on all questions.
- Any number of people may work on a single entry.
- All entries will indicate the name, school, and grade of each participant responsible for entry construction.
- Entries will be disqualified if materials other than those furnished in the kit are used. Wood glue and "super" (ACC) glue are not allowed.
- The design of the bridge must accommodate the test load apparatus. Loading will be applied to a 2" x 3" plate placed on the roadbed in the center of the span. A 1" x 1" x 3" (tall) block will transmit the load to the roadbed plate. Any construction above the roadbed should allow the block to pass through an opening in the center of the bridge. Any construction below the bridge must be less than 1".
- The bridge MUST be configured as a truss. If the materials are glued together as a "log" in any form, the entry will be disqualified.
LOADING SPECIFICATIONS
- The model will be loaded until failure.
- Failure is defined as a permanent decrease in the load carrying capacity.
- The load will be applied to the roadbed and a minimum of 50 lbs must be carried.
BRIDGE DIMENSIONS
Length: 12 inches
Min. width: 3 inches
Max. height: 4 inches
JUDGING CRITERIA
The model that demonstrates the highest efficiency ratio well be declared the best entry.
The efficiency ratio refers to the amount of weight that the bridge holds at the point it fails (i.e. breaks) divided by the weight of the bridge. For example if two bridges both fail when loaded with 150 pounds of weight and bridge #1 weighs 50 grams and bridge #2 weighs 75 grams the efficiency ratios would be:
Bridge #1 Efficiency Ratio = 150 lbs/50 grams = 3 lbs/gram
Bridge #2 Efficiency Ratio = 150 lbs/75 grams = 2 lbs/gram
You can see from these calculations that bridge #1 has the higher efficiency ratio and consequently would be a higher rated bridge than bridge #2. At the end of the competition the bridge with the highest ratio in each division (high school and middle school) will be declared the winner.
