Am I missing something , or have you guys left out your main breaker? It looks like the Anderson connector for the battery goes right into the power distribution board...

WOW yeah that could be a serious issue with the inspectors

The breaker may have fit more conveniently somewhere else, so they may just be plugging it in to the plug on the power distribution board. Also, I doubt this is the entirety of their electronics, I may be wrong, but I bet their using more than just two motor controllers.

Actually It doesn't look like the breaker is attached to the anderson connector on this board. Picture seems pretty clear about it.

They probably have it connected separatly on another part of their robot. Just like they have the quick disconnect for the motors, they have the same for the on off switch. Looks like its to make sure thay can easily remove the board, yet keep the main breaker in a place that's easily accesible.

Wow!!! Two things:

1) That's a really amazing board, love the two level design, love how everything is mounted together with minimal spacing but little chance for shorts. I like how there are Anderson connectors to allow the entire board to be dismounted and moved. I'd like to see the far side power connectors to see how they are arranged.

2) I'm surprised how the first batch of responses were negative. From the picture and the text above and below you can tell they thought things through, unlikely they would "forget" the breaker.

Cool board team, I hope you win an award for it.

Exactly, the on switch stays on the robot while the board can come out if work needs done. The other nice thing is all of those components are mounted on surgical tubing to help absorb some of the impact if we don't go over a bump as smoothly as we'd like.

Re: pic: Team 701's Electronics

so it looks like you are using no pneumatics. and did you know that you can make a ribbon cable for your digital sidecar so you dont have to have that huge thing coming out of your board. also are you not using pwm, but using a rj11 jack, and how does that work?

They are using the CAN bus. The first black jaguar is connected to the cRio via RS232 (serial), and the rest are chained to it via CAN.

Woah thats nice and small i like it!!! i had to do a double take you you said 10 jaguars

Re: pic: Team 701's Electronics

Using CAN sure does clean things up a ton! We're still using PWM this year, making the board more unruly to keep nice. Nice job 701.

Hmm... interesting... no Spike Relay suggests to me that there's no compressor.

Mind you, with TEN jags, I suppose you might not need one. Let's see... four CIMs and two FP on the drive train... one CIM for a winch, two window motors for a kicker (or vice versa) and... a mabuchi for a ball magnet?

I like your design, especially the remote main breaker idea. We're doing something similar, but have put our main breaker and our solenoid valves into our "control box".

It will make up about 20 pounds of our witholding allowance and fits nicely into both the 'shipping' chassis and 'practice' chassis.

Jason,
You're thinking too much again. Shouldn't you be watching the Olympics or something?

Re: pic: Team 701's Electronics

Very very nice.....much like some of the aircraft stuff I used to deal with. Ill have to stash that idea away in my head for next year. Oh wait....we haven't even gotten ready for this year yet, what am I thinking!!!

Well, all the same...love the modular idea. Our bot this year is no way near that elegant, in fact more of the opposite view thinking " keep everything out in the open so we can track the fasteners that might fall out and know what caught fire first " for damage control purposes.

It looks so much better than ours. Seriously, ours looks like it's spaghetti.

Re: pic: Team 701's Electronics

Correct, no air system on this robot, and you were sort of close for the motor guesses.

4 CIMs to drives.
1 CIM to winch us up
2 Windows to move the arm
2 FP's to kick
and a Mabuchi for our roller.

What kind of quick connectors are you using for the jags and where can I find them???

Re: pic: Team 701's Electronics

They are using Anderson power connectors, they can be found through many online retailers.

Re: pic: Team 701's Electronics

Very nice wiring job. I like it.

If room on the robot permits, you might (!) want to consider moving the "radio" away from so much metal. The antennas inside the D-Link work better away from all metal (as much as possible). It should be OK where it is, but if it can be moved you might find it better.

Re: pic: Team 701's Electronics

Haha thanks for the suggestion, but this electronics board is actually from 2 years ago when i was a senior on the team. This year's electronics are different, and still a work in progress. Thanks for all the constructive criticism though.

If anyone has any more questions about it feel free to ask, i'm more than glad to answer.
