After printing the original Makerbot Botmobile and having trouble finding the right motor, gear and battery combo I decided to redesign the drive train and some other components in order to make it easier for everyone to get a functional Botmobile up and running.

Video of the brush version of the car in action: [http://www.youtube.com/watch?v=22fwVmX2GA8](http://www.youtube.com/watch?v=22fwVmX2GA8)

Full credit for the original design goes to the guys from Makerbot

Changes & Upgrades for the 2013 Version:

• Drivetrain re-designed for the use with standard, of the shelf 280 brush as well as brushless motors
• Drive gears modified to be fully printable and support the stronger motors
• Body changed to accommodate 2S LiPo Packs
• Additional mounting points added to the body to make the chassis more rigid and prevent the 2 body parts and the interior from separating
• Steering updated to allow for better control and tighter turns
• Receiver slot enlarged and additional RX brackets provided to allow installation of a larger variety of receivers.

• Updated assembly manual with full parts and source list

  All parts are tested and print fine on a Replicator 2X (ABS) using Makerware.

Please refer to the downloadable Manual.
