VEXpro Drive in a Day Project

On Sunday, January 6, one day after the 2013 FIRST ® Robotics Competition Kickoff, the VEXpro team designed, prototyped and built a robot chassis and drivetrain intended for use by FIRST ® Robotics Competition teams in the 2013 game, Ultimate Ascent.

The entire project was documented on the VEXpro Drive in a Day webpage and in a Google Document so teams can understand our engineering design process and see why certain decisions were made.

Our goal was to design a Superior Performance drivetrain to provide to teams to play Ultimate Ascent at affordable & accessible cost. The teams that this chassis are designed for include:

  • -Mid-level teams looking to play with the pros
  • -Teams that can't build this level of drivetrain, but want to move beyond the Kitbot
  • -Teams that can't build this level of drivetrain without help
  • -Teams that can build this level of drivetrain, but might want to spend their time on other things in this difficult game

We welcome all feedback and questions from teams on this product. Please contact us at support@vexrobotics.com or 903-453-0802.
