EGR 101 and EGR 345 Project - Spectacular Robotic Min-ing (Fall 2007) - Last Revised October 9, 2007NOTE: This version is not final and subject to major changes4.1 OVERVIEWThe project is intended to emphasize proper project management and team skills to produce a complex engineering system from concept to completion.The combined teams from EGR 101 and EGR 345 will place their apparatus on opposite sides of the playing field. Each team will consist of up to 6 EGR 101 teams who will feed ore (practice golf balls) to an EGR 345 robot in a designated transfer zone. The EGR 345 robot will then transport the ore to a central depository (a bucket). The EGR 101 robots can be controlled remotely using electrical connections (i.e., wires, switches, etc.). The EGR 345 robot must be self contained, and cannot be controlled with any physical means. The teams will compete head to head over a 5 minute period to deposite the most ore in the bucket.The competition for EGR 101 and EGR 345 students will be held Saturday December 1st, 2007.4.2 RULES1. The geometry of the playing field is shown in Figure 1. The endzone is where EGR 101 robots must start, and where balls can be reloaded. The transfer zone is where the EGR 345 robots and other related components must start, and where balls can be transferred from EGR 101 robots. The bucket will be placed in the middle of the field approximately at the center, but it will be free to move during the competition. The walls will be approximately 7 1/2" tall. The floor will be concrete, with black electrical tape lines for the boundaries of the zones.egr345 lab guide - 4.2Figure 1 - Playing Field2. At the start of the competition all of the robots must be in their resplective zones. EGR 101 robots are not permitted to travel beyond the front of the trans-fer zone. EGR 345 robots must not travel any further back than the back of the transfer zone. Robots may not enter the zones of the opposing teams.3. The EGR 101 robots may not be touched when outside the endzone, including the loading of balls. A tether consisting of wires may be used to control the robots. It is recommended that motors be used to drive the robots.4. The EGR 345 robots must be self contained. Once the competition starts the robots must not be attached by any tethers for control or power delivery. Wire-less communication is permitted if using the CC2500 RF modems.5. Teams will be awarded bonus ore for the following criteria,+1 for each 100g under 4kg for all equipment combined+1 for each $10 under $300 for all equipment combined+1 for (Others to be considered)6. Teams or individual robots will be disqualified for the following reasons.- Causing major damage to the playing field or opponents robots.- Entries are deemed unsafe- Unprofessional construction including duct tape, card board, etc.- Failure to setup during the 2 minute setup time.7. The EGR 101 robots can carry one ball between the endzone and the transfer zone. The balls may be loaded by hand when the EGR 101 robot is complete 4’16’bucket end zoneend zonetransfer zonetransfer zone1’ 18" 18" 8’Team ATeam Begr345 lab guide - 4.3inside the endzone. The ball can be transferred to the EGR 345 robot when it is completely inside the transfer zone.8. Balls and other obstructions will not be removed from the field.9. The competition will be 5 minutes long and there will be an unlimited number of balls available for each team. Teams will have 2 minutes to setup.10. The bucket will be approximately 12" in diameter, 8" tall, and may have a slight taper. The center part of the field, between the transfer zones, may be lightly lubricated. The bucket can move anywhere between the transfer zones. If a team moves the bucket into any zones they will be disqualified. The bucket cannot be captured, or held, in any way that prevents the opposing team from depositing balls. 11. The ore (practice golf balls) are approximately 1.5 +/- 0.1 inches in diameter. The Balls that will be provided are similar to ’Top Flite 24 Practice Golf Balls’ purchased from Target for $3.99. (model # 59016-White).13. EGR 101 Components that may be purchased include those listed below. Exceptions are permitted only when approved by Dr. Sirkus on the Blackboard website.- Tamiya brand gearboxes- Wheels and tires- Fasteners (nuts, bolts, threaded rod, etc.)- Electrical components (Motors, switches, etc.)- Pneumatic components (Cylinders, fittings, etc.)Prohibited materials are listed below. Using these will result in immediate disqual-ification unless approved on Blackboard by Dr. Sirkus.- Cardboard- Paper- Tape of any form (duct, electrical, masking, etc.)- Refuse materials (bevarage containers, paper towel tubes, etc.)14. EGR 345 teams are expected to use professional construction techniques and materials. This rule is somewhat subjective, and if there is any doubt teams are to ask for
