Re: [DFTF] Budgeting for a Competitive Robot...
With no old robots to rob for COTS I would say that you need $4000 dollars to build a single competitive robot.
$1500-2000 You need to buy transmissions and other power transmission hardware (gears, sprockets, chains) that can easily run this range with reasonable spares and failed concept fallout. $200-300 Wire, nough said $600-800 Motor controllers, you only get 4 in the kit of late and this is always the painful number to see. $250 Fasteners: nuts, bolts, rivets, zipties, master links etc to stock up. $200 Additional motors, you only get 2 of the CIMS in the kit and you need to buy more if we get to use 4-5 again this year. Banebots motors have had many issues and we never go into battle without spares anymore. $200 Bearings: we use a lot of bearings and bushings. But we also build lots of spares and failed concepts. $300 Bumper, fabric wood and pool noodles. $1000 Shipping: to get the parts to you... $500 Additional raw materials $200 Solenoid valves and other pnuematic parts. $200 Cutters for machine tools. This is all best guess from memory. I know when you add all this up we easily spend $4000-5000 every year on the supplies to build a single robot. We also have a lot of spares, fallout from concepts that don't make the robot, and shipping costs to bring our robot in under the typical $3500 limit. I have to say with the cost of electronics consuming so much budget when we account our cost I would like to see it go to $4000. We are close every year to that limit, because we are honest to a fault with our accounting, and the electronics is a big factor. |
