2. Expect to put in more time on your drive system than you originally estimate. If you cannot move around, you cannot use those wiz-bangy fancy devices that you have mounted on top of the drive system. 3. Stay focussed on the drive system until it actually works. This includes breaking, redesigning, and fixing. 4. Don't forget that you have to wire it and program it and put together an operator interface too. If you have a complicated drive system, you will need to invest some more time and resources in programming (and variables). 5. The more complicated the drive system, the more training time will be required to drive it effectively. If you get 10% performance out of a spectacular system, you may not be as effective as someone getting 100% performance out of a simpler system. 6. Sometimes differential back wheels and front-casters work. But they have lots of hidden disadvantages, especially if there is a hill in your future. 7. Consider forced air cooling of your drive motors using the fans in the kit. 8. You have limited resources. The more resources you devote to your drive system, the fewer resources are available for other devices. 9. Make it robust. If you plan to attend more than one event, your drive system is going to take a beating. 10. Buy extra drive motors (if possible). The drill motors only go for about $25 each. You don't want to have your entire competition go down the tubes for the lack of a $20 part. Buy extra 30 amp breakers. 11. Make your drive system easy to get to and easy to replace/repair. If you have to disassemble your robot to tighten that one loose screw, you might miss matches. Quote:
2. Qualitatively determine what the attributes of each system are (speed, maneuverability, power, complexity, etc.) and assign a value. 3. Look at the game and determine what strategies are available. 4. Assign attributes to the strategies (maneuverability, speed, etc). 5. Pick strategy and assign weights to the drive system attributes based on that particular strategy. 6. Add up the value*weight for each drive system. Make a decision based on which one floats to the top. Andrew, Team 356 |
