For Sale: Ramming Speed II

This light weight BattleBot was built for BattleBots 5.0. It was finished too late to test well, and could not compete (failed functional safety test due to the motors being geared to high). The design is an elegant, very compact and durable rambot. The official BattleBot weight is 50lbs, which allows weight for modular attachments to be mounted (ie a wedge, spike, flat pushing bar, etc) to already tapped holes on both ends of the bot (note that these attachments are not included, they were never finished). To compete with this bot, changes must be made to the motors, at a minimum, lowering the gearing, maximum would be replacing the motors as recommended below. The addition of a transmitter and receiver, and battery charger complete the package (all available through me at additional cost). Note that the name and points associated with the BattleBot Ramming Speed are not included. The package for sale includes:

Frame: The frame is made from 3/8" 304 Stainless Steel. The metal was cut with a water jet, and welded to 3/16" 304 Stainless Steel angle iron on front and back. The bottom is .06 304 Stainless, also welded to the frame pieces to form a unibody. The top, is also .06 Stainless, which screws onto the frame through 32 tapped holes. Note in the pictures that the top had to be modified to pass safety, which required the openings for the removable links be enlarged. See the drawings used to cut the frame here.
Power: Power is supplied by two custom BattlePacks. Each pack has 18 cells, providing 21.6v for a total of 7.2ah. These packs have only been cycles 3 or 4 times. The packs are specially wired to include switching through a removable link (left pack in the pic has the link in place), and can be charged while in the bot through this connection as well (right pack in the pic has charging cable attached). They are then covered in thick shrink-wrap.
Electronics: The all electronics required to run the robot are included except for the receiver. A Futaba R113IP receiver will be a plug-n-play drop in. The receiver is powered through a Team Delta DC/DC converter. The receiver connects to a IMX-1 invertible tank mixer, which serves a few functions, including allowing the controls to be reversed should the robot be flipped. The IMX-1 connects to to Victor 833 speed controllers. The controllers have had the stock fans removed, and instead 12v CPU fans are being used at 24v, which are more compact, yet offer more air flow. All of this is housed in an aluminum and Lexan housing that is easily removed from the robot, while keeping all components attached.
Motors: This is where I ran into problems. The bot includes 4 of the new style Dewalt 18v motors and transmissions. This motor/transmission combo does not bolt together, so I created a polyurethane housing, to hold them. The problem was that the transmission offers three speeds, and I chose the highest, hoping for maximum speed. This proved to be to much effort for the motors, which tend to smoke a bit. They still seem to work, but the gearing will definitely need to be changed, or the motors completely replaced with another option. This could include 4 of the older style Dewalt motors (if I were to attempt to compete again, I would buy 4 of the Dewalt 18v setups, with mount and spindle from TeamDelta). 4 Astroflight motors should also fit and offer a good amount of power and speed.
Drive Train: W.M. Berg FlexiGrip sprockets are used to drive belts. These belts are strong, will not stretch, and the design of the bot helps assure the cannot come off. The wheels are made from Sears 3" Spindle Sander spindles. The rubber is very grippy and soft enough to provide some 'shock protection' for the 1/2" Stainless Steel axles. The wheels are directly attached to the sprockets via Stainless Steel screws, removable through access holes in the frame. It would be very easy to replace the wheels with dual 3" Colsons on a hub if a more standard wheel was desired.
Value: Here are most of the items included in the package, including what I paid for them. All items work perfectly, with the possible exception of the motors which do run, but have smoked a bit. With screws, terminals, washers, and other misc. items, their is easily close to $2800 of components included.
