  • Clarifications, Alterations, and FAQs
  • Note: These changes were meant to make your life easier. If, for some reason, one of these alterations puts a serious wrench in your plans, please come talk to the staff.
    • Budget. Total budget is $1200 max. Of that, you have up to $800 for Caltech purchases, and up to $400 for external purchases, approval required. Teams should be advised that external purchases will be approved only after review on a case-by-case basis. Teams should keep in mind that the radio controllers, speed controllers, servos, batteries, and battery chargers need to be returned at the end of term.
    • Recycling Bins. The contest rules specify bins will range in height from 10-16" inches. Instead, they will range from 6-12". In addition, bins will not be labeled. You may choose the order in which to place your sorted recyclables (ie you choose if you want plastic-steel-aluminum or aluminum-plastic-steel). When the heat ends, before recyclables have been counted, your team must declare which bin contains which category.
    • Terrain elements. The size of the terrain elements will be extended to 3x10' each. Course size will change accordingly; you will still have a couple feet to maneuver between terrain elements.
    • Ramps. The water element will have ramps inside, of the same dimensions as the outside ramp. There will be at least 2 ramps for every element.
    • Purchasing. In general, you must use the radio controllers, speed controllers, and batteries from the shop (there may be exceptions if you have a good reason). You may use motors from outside vendors. You may not buy and use entire assemblies, except for transmissions (but dismantling something and using part of it is OK).
    • Crushing. A can will be considered "crushed" if it is half or less of its original vertical height. This means that crushing a can sideways will not alone constitute crushing.
