Colsonbot, ColsonbotDoes whatever a colsonbot doesCan he spin? Can he win?YES HE CAN!He's a wonder!\nColsonbot is a 3lb weight class ("Beetleweight") combat robot that thrives in an 8" caster wheel (hence the Colson name). It's a quick, agile shell-spinner design with a brushless friction-drive system for the shell, that excels in competition if only it didn't live inside a wheel. Colsonbot is a peaceful, non-aggressive combat robot. Perfect for FIRST Robotics competitions.\nPrint Settings\nRafts: Does matter Supports: Yes Resolution: 0.20 Infill: 90 to 100% Notes: Colsonbot was printed in ABS using a Dimension 1200ES, but has also been printed in PLA and Nylon. 100% fill, or sparse fill with many shells, should be used for strength. Most important areas for strength are the central tower that supports the 5/8" bolt.\nPost-Printing\nAssembly Instructions\nColsonbot uses the following parts: QTY 4: Fingertech Robotics Silver Spark 11:1 QTY 4: McMaster-Carr P/N 9600K53 rubber grommets QTY 2: Vex Robotics 29 Motor Controller QTY 1: Hobbyking Zippy 1000mah 3S/25C LiPoly battery QTY 1 or 2: Hobbyking NTM PROPDRIVE 2830 motor QTY 1 or 2: Hobbyking TURNIGY PLUS 18A brushless motor controller\nUse flathead #4 x 3/8" coarse-thread sheet metal screws, or Plastite/threadforming screws for plastic to assemble the covers. \nTo use a 8"x2" Colson Performa wheel as the spinning shell, it must be machined hollow using a lathe. A size PFR-2214 bearing, 5/8" bore, fits into the wheel center. The part "Spacer for PFR-2214 Bearing" is to space out the bearings axially (along the center shaft) only.\nThe center shaft is made using a 5/8"-18 hex-head bolt whose head is machined down to 1/8" thickness.\nA full report of Colsonbot's build can be found here: http://www.etotheipiplusone.net/?p=3718
