Re: pic: Skunkswerve....team 1983
Nice job on the CAD, have fun with that insane drivetrain.

Re: pic: Skunkswerve....team 1983
Excellent. It's like a wide side variation of what we're building!
Have you considered powering each wheel independently, via banebots or DeWalts, in order to make a traction control system easier? |

Re: pic: Skunkswerve....team 1983
Looks like more great work from the Skunks. This will be a great design to show off swerve drive concepts to the dozens of WA rookies this year.
Looking forward to seeing it go! Jason |

Re: pic: Skunkswerve....team 1983
To answer some question, we are using a coaxial design for the steering/power shafts.
We considered powering all four "cans" independently, but decided that a half swerve design with a CIM powering each side would provide enough flexibility for control. As of now we can orient the front and back pair independently in addition to powering the front and back separately. Our team discussed implementing a traction control system, but we decided that it could hinder the driver’s ability to control the robot, much like the Airbus fly-by-wire systems that have caused pilot/computer “disagreements.” |

Re: pic: Skunkswerve....team 1983
Aren't you missing tensioners for your toughbox (or dewalt) chains? Sliding the toughbox/dewalt back and forth won't work since you'll have different amounts of slack in both chains. Or am I missing a second set of slots crosswise to the set I can see?

Very nice work 1983! Keep up the great work and we'll see you in a few weeks.

Re: pic: Skunkswerve....team 1983
The transmission is offset from the center of the robot, the chains will be different lengths so sliding the toughbox or Dewalt will tension both sides. If that method does not work, we are planning on making some of our own AM style tensioners for use with 25 chain.

Re: pic: Skunkswerve....team 1983
I share the same emotions as Asa: It's scary how similar it looks to our design as well.
Looks very solid. Do you have a weight estimate? Best of luck to you in fab. |
