Foreword

Each school MUST preregister one week (5 business days) prior to the date of the Engineering Fair. Visit oef.org for registration information. Upon registration, the participants will receive an entry form via email, which must be completed and attached to their bridge. Prizes will be awarded to winning entries from registered schools (entries from unregistered schools will NOT be eligible for prizes).

Design

Prior to the Fair a STUDENT bridge builder must design and build his/her own bridge. All design and building techniques should fall within the specifications that follow. Tolerances are given in the specifications. Should any bridge fall outside the tolerances, that bridge will be disqualified or the builder may attempt on-the-spot modifications to bring the bridge within specifications. Each bridge must be free standing.

Note: While adults may aid the student with suggestions, etc., the bridge must be built ONLY by the student ¾ NO ADULT CONSTRUCTION ASSISTANCE IS PERMITTED.

Objective

The Drone Competition is a virtual competition. The goal is to design and build an obstacle course and to fly and maneuver an Unmanned Aerial Vehicle (UAV) or drone through the course as fast and as safely as possible. The drone you use can be one that you have purchased or it can be one that you have designed and created on your own. Students will submit a video of their course and UAV/drone flight through the course by February 15, 2023 and will then participate in a video interview with judges at the Engineering Fair.

Design Statement

Each entrant / team is responsible for creating an obstacle course which allows your drone to fly over a structure, through a structure, and under a structure. There must be an obvious start and stop location. Participants can purchase a drone or build one from scratch. The obstacle course and drone will be judged by:

• Creativity
• Obstacle Difficulty
• Ability to employ (3) safety mechanisms
• Ability to hover drone, as well as ability to maneuver over, through and under obstacles
• Complete course within a 5-minute time limit
• Extra points given to those participants who design/create their own drone

For those participants that opt to create their own drone, a Parts List must be provided. This list should indicate the source, cost, and fabrication operations for the drone.

Materials & Restrictions

Costs in materials in constructing a drone is restricted to a $250.00 or less per drone (this does not include an FPV (first person video).

Common vendors for purchasing drone kits include – Amazon, Hobby King, Get FPV, and Ready Made RC.

FOREWARD

This number of entries per school is unlimited. Each entry is a team project, conducted by two students.

Each school MUST complete a Fair Registration one week (5 business days) prior to the Engineering Fair. Entry forms must be completed and handed in at time of competition check-in on the day of the Engineering Fair. Prizes will be awarded to winning entries from registered schools (entries from unregistered schools will NOT be eligible for prizes).

Objective

Prior to competition, design and build an electric motor powered by a dry cell battery that rotates at the highest possible speed.

Design Statement

Each entrant will design, build and test a Horizontal shaft electrical motor. The motor shall be powered by one readily available non-rechargeable dry cell battery. The motor is judged on its highest rotation speed with no load. The motor may be started by hand. The motor is to be constructed from materials and simple hardware readily available at retail stores or mail order suppliers. A design drawing and parts list indicating the source, cost and fabrication operations for each part must accompany the motor.

NOTE: The motor must be built by this year’s contestant and not by a previous year’s contestant.

Materials & Restrictions

The power must be derived from one non-rechargeable dry cell battery. The maximum nominal voltage shall be one and one-half (1.5) Volts. A single flashlight battery up to D size may be used. Batteries may not be paralleled. The battery is supplied by the entrant and may not be replaced during a timed contest. The battery may be replaced between the first and second trial.

Readily available permanent magnets may be used.

Industrial quality or other professionally manufactured components are not permitted. Manufactured kits will not be allowed.

Electrical and electronic components such as switches, resistors (variable and fixed), capacitors, inductors, relays, transistors, integrated circuits and interconnection hardware readily available through local retail or mail order sources may be used. Pre-manufactured subassemblies such as armatures, field structures, computer, or controller modules will not be permitted.

Materials such as wire, cable, string; wood, plastic, permanent magnets, metal sheet; bar and rod stock; common fasteners such as nails, screws, adhesives, staples and rivets; wheels, pulleys, bearings; and other common items readily available in local retail stores may be used.

Toy or hobbyist type articles such as erector set structural components may be used. Major components such as armatures, commutators, or field structures from motors or motor kits may not be used.

NOTE: A design drawing clearly labeling each component and a corresponding parts list must accompany each motor. The parts list must indicate the source (vendor), cost, machining and fabrication procedure for each component.

Design Statement and Objective

Prior to the competition, each team will design and build a launcher which can catapult ping-pong balls at targets (#10 Cans 6 inches in diameter x 7 inches tall) located 12 feet from the launcher table. Launcher must shoot only one ball at a time and should be re-loadable in order to launch as many balls as possible within a three-minute time frame.

2023 The Wacky Wonder Works Competition is sponsored by the Oklahoma Society of Professional Engineers, Central/Southwest Chapter. 

FOREWARD

The Wacky Wonder Works (WWW) Competition uses modified Rube Goldberg machine contest rules to test student’s engineering skills. Please review the current rules below as some have changed from past competitions.

This contest is limited to four (4) entries per school. Each entry is a team project; conducted by no more than six team members. An individual student may NOT participate on more than one team. Only one entry per team is allowable.

Each school MUST complete the Official Entry and Project Description Form found on page 5 and submit it to the OEF office by Tuesday, February 21, 2023, at Noon (Central Time). It is critical that all actions are listed. Prizes will be awarded to winning entries from registered schools.
