Team 1565 Unique Drive System
 

Here is Team 1565's "Linkage" drive system at about beginning of Week 3. http://www.youtube.com/watch?v=RvN4K2ieR5g Some programming bugs in it still, but its still really cool.

ps. our mentor who is video taping seems happy lol.

I have always dreamed of building a drive system like this, but you guys actually did it. Excellent job. You are definitely in line for an innovation award if you play your cards right.

can we see some up close or a description of how it works

Re: Team 1565 Unique Drive System
 

I can get pictures up of it tomorrow when I can get them downloaded on my computer, description will follow lol

Re: Team 1565 Unique Drive System
 

Awesome! About how much pressure does it take to swivel the modules each time?

Re: Team 1565 Unique Drive System
 

it takes about 30psi to move the linkage now, It moves better now than in the previous video :D

Re: Team 1565 Unique Drive System
 

Yowzers, that is way too cool! Looks like there is a single cylinder on the bottom (pointing lengthwise) that holds all of the wheel modules in the 'forward' position when extended and holds them all in the sideways position when contracted. Very creative way to give your robot more mobility, and it doesn't use any extra motors!

Nice work.

Re: Team 1565 Unique Drive System
 

Nice concept. Looks like you've got good power any way you go. Any specific reason for the decision of omni wheels? Would ~0.75" wide traction wheels work just as well or no?

Re: Team 1565 Unique Drive System
 

I love your drive system. If you guys do not win creativity i will be shocked.:eek:

Re: Team 1565 Unique Drive System
 

Amazing! How much does that weigh, because with almost full weight, all 4 cims and already a pretty big strain on the compressor, are you going to have any sort of device?

Re: Team 1565 Unique Drive System
 

Unique is a huge understatement. Very nice, and that looks darn near unbeatable going around the 'racetrack'.

That's the most amazing thing I've seen all week. :] It's a thing of beauty.

I completely agree with the π-o-neers. Say hi to your FTC team 470 would ya? im on FTC 232 they'll know me;)

Re: Team 1565 Unique Drive System
 

As i'm watching the video, i'm thinking:

wouldnt it be cool if the wheels all rotated half way (45 degrees), then all the wheels are 90 degrees to each other and it becomes holonomic drive....

but....yeah. totally unnecessary. Definately a sweet looking system. Congrats! i'm impressed!

Re: Team 1565 Unique Drive System
 

funny story about that.. They did. We had a three stage so we can drive in omni for standard avoiding robots, but programming it turned out harder than we thought, and because nothing else on our bot needs air, we decided to just go for the two stages
