Choosing Drive Train By Janavi

Task: Analyze the game

In our last post, we created a chart where we listed each task asked based on point value and the level of difficulty, separated by autonomous and teleop. Our goal is to find a drive train that will allow us to build a robot to accomplish all of these tasks efficiently and consistently, but this matrix will allow us to determine what to focus on first.

Drivetrain Comparison

This summer we created a variety of drivetrains for a summer chassis project hosted in coordination with other teams from the North Texas region. We have compiled a list of the drivetrains and the criteria we need to consider for Rover Ruckus.

What do we need to look at in a Drivetrain?

  • Light
  • Sturdy
  • Easily Maneuverable
  • Fast
  • Low center of mass to avoid tipping
  • Reliability


Eliminated? Reason for Elimination Pros Cons
Miniature Mechanum Drive NO N/A
  • Omni-Directional
  • Fast turning
  • Easy to design
  • Experience with
  • Driving/Building
  • light
Uneven power
Big Wheel NO N/A Unique Design We have less experience
Larger Mechanum Drive YES Need light robot; may use mini mechanum chassis instead Familiar Design Too heavy for this years competition
Swerve YES Difficult design, Many motors and servos, we have less experience Easier to maintain at high speed Unfamiliar and difficult to design and maintain
8-wheel Drive YES Many wheels, Difficult of maneuver, no omni directional movement 100% power forward Difficult to maneuver
Holonomic Drive YES Less push power in all directions; hard to integrate into robot Easy to turn and maneuver Hard to design; hard to integrate into base; Only 50% power in all directions
