Neat design. The University Rover Challenge might be of interest to you.

Wow, really?! I didn’t know you could do that :stuck_out_tongue: I’m working on finishing the full model of this first, and I’ll integrate that in the second revision!

That looks absolutely amazing! I’m a freshman with no money though.

It’s for university/college students, so there is time to plan your design. :cool:

This will work nicely with the replay of the 2010 bumps in next years game.

The Mars rover linkage suspension was designed to keep all the wheels pointed the same direction while allowing them to go up and down. With swerve modules, I don’t see that this makes much sense. I’d put those modules on tripods mounted to the chassis with ball joints, or perhaps orient the lower bearings perpendicular to the uppers, and arrange the nominal drop points of the modules to be something more like a regular hexagon than two lines of three.

Sorry, I don’t quite understand what you’re saying. T-T

I don’t think having swerve modules undermines the drivetrain’s differential at all, as the modules are able to point forwards when need be, and allow the bot to have greater maneuverability when turned. You’ll notice that the rover utilizes swerve modules as well on four out of its six wheels, with the middle two locked in place. This allows it to turn about its center, as opposed to having to drive like a car to turn 180 degrees.

Of course, I may be wrong/misinterpreting your point, but I think that using swerve drive modules here is an acceptable (and useful) application.

I’ll definitely think about it. The MIT rover competition also looks cool, though, and I know someone who competed in that a couple years ago. They had swerve drive and a 6-axis arm, and their bot was totally awesome to look at. I never got to see it working, though.

I never thought of this. This sounds like a fantastic method for teams that don’t have some decent machinery.

I competed in this competition in college, it was a blast.
