Choosing Drive TrainTags: design, think, and innovate
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.
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?
- Easily Maneuverable
- Low center of mass to avoid tipping
|Eliminated?||Reason for Elimination||Pros||Cons|
|Miniature Mechanum Drive||NO||N/A||
|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|
