Re: pic: I was bored... so I designed this.
Thanks for all the complements about the render and design.

![]() (the image is a little squashed so it looks a little off) About the module itself: The main body of the module is machined out of a 3" long piece 5"x3"x1/2" Aluminum Angle. The top of the main body of the module is adapted from my teams current swerve drive module design. Also I did not want to cantilever the bevel gear so I went ahead and supported the bevel gear shaft on both ends. (This module was designed just for fun really so there may be issues I am unaware of). I welcome any advice and comments about the design. Last edited by Garret : 20-12-2011 at 17:03. |

Re: pic: I was bored... so I designed this.
Just out of curiosity, what are the benefits of 6 wheel swerve over 4 wheel swerve?

Re: pic: I was bored... so I designed this.
The benefit of a six wheel swerve over a 4 wheel swerve is that the six wheel can act like a standard 6WD.

Re: pic: I was bored... so I designed this.
that's only really an advantage compared to swerves that can't independently steer each wheel

Was 1625s 6 wheel swerve coaxle?

I'll let the search function handle that question

Re: pic: I was bored... so I designed this.
I don't understand. Why would you go to the trouble of building an extremely complicated drive so it can approximate the functionality of a very simple drive?

There are two main solutions to this: 1) do a module style (non-coaxial) swerve or an independently driven (ala Emperor Swerve by 973) which allows the wheels to always turn such that they are not skidding when making a center turn or 2) make your code so that you don't make turns like that most of the time (as 40 used to do, with quadra-steer). If you add the extra set of dropped center wheels, you get all the benefits of a swerve drive, but you still have the non-swerve driving characteristics of a 6wd. |

Re: pic: I was bored... so I designed this.
Just to add a quick point onto Evan's post: A 6WD swerve, in theory should also handle climbing objects a little better, depending on the object and the implementation of the swerve. A 4WD swerve would require quite a bit of ground clearance at the center, which may or may not be advantageous. A 6WD swerve would need ground clearance similar to a conventional 6WD. (For more clarification, look at some of the 4WD robots from 2010 vs the 6WD robots and you'll see what I mean.)

Also, the other solution is to drive each side independently, and then turn corners together.

The title of this thread is "I was bored... so I designed this."
How much time did you spend on the design? I see a number of these every year and figure that there are hours and hours spent. Thanks! |

Re: pic: I was bored... so I designed this.
Sorry for the late response I have been busy the past few days. I spent about 4 nights working on this design. I designed this in 4 stages, I started with the module design, then I designed the mounting set-up, then the frame, and then finishing the assembly. Each stage was about a day of design.
