Totally unnecessarily awesome... :cool:

Re: pic: 148 Follower Wheel Assembly
How is this going to measure ground speed if it can't touch the ground?
|
Re: pic: 148 Follower Wheel Assembly
It can.
The GDC has ruled that similar devices do not count as "traction devices" in the Q and A. |
Re: pic: 148 Follower Wheel Assembly
It was asked in the Q&A and they said that if it does not provide traction than it can touch the ground. The actual rule says that the rover wheels are the only thing that can provide traction, not the only thing that can touch the ground.

Here is a relevant Q&A on the subject

Re: pic: 148 Follower Wheel Assembly
We were planning to do the same thing, but with all vex components, including the new encoders. Hadn't gotten to it yet.

Re: pic: 148 Follower Wheel Assembly
Fabulous use of VEX parts in a very elegant package. I think we'll be seeing a lot of similar assemblies this year.

Re: pic: 148 Follower Wheel Assembly
Humm - how much bigger than the green gear is that omni wheel? The reason I ask is because on the carpet, the wheel may sink in enough to allow the gear to grab some carpet fibers.
Also, is it just pivoting off the robot frame from that empty set of holes, and thus using gravity to keep it in contact with the floor? |
Re: pic: 148 Follower Wheel Assembly
If you are just using gravity to maintain contact with the ground have you tested to see if it slips at all when driving on the regolith?
|
Re: pic: 148 Follower Wheel Assembly
Beautiful assembly!
Have you tested whether it will stay on the ground under its own weight? If not, may I suggest gas springs! |
Re: pic: 148 Follower Wheel Assembly
Correct me if I'm wrong, but are those delrin sideplates? They look very nice. Good luck with this. =)

Re: pic: 148 Follower Wheel Assembly
I like the fact that black gear is an ABS rapid prototype. Want to clue the world into the right pitch for interfacing with a vex gear?
|
Re: pic: 148 Follower Wheel Assembly
Soo.... will Vexlabs be selling these?
