I think they're only using two CIMs for drive now.

Re: pic: Team 254 2006 Robot 1
 

Ah, my mistake. Regardless... I have not seen a CIM stall in FIRST. EVER.

I disagree. If both robots have the same amount of traction, the bot with more ability to turn the wheels will do just that, turn the wheels. A slightly mocked down version of burning out. I believe the lower RPMs help in a situation like that, putting more grip to the floor. Plus the higher load CIM is running more efficiently.

Just for the record... adding motors normally does not increase pushing ability, just range of top speed.

It most certainly does increase pushing ability. More motors means more torque, which as long as you haven't exceeded friction*Normal Force means more pushing ability.

If you meant to say it increases pushing ability at higher speeds, you'd be correct, but it definitely does not increase the top speed of the robot.

I really am getting into a bad habit of not thinking things through, sorry. I meant it gives the potential for a higher speed. More torque due to more motors leads to the ability to turn a higher gear ratio resulting in a higher output speed.

More motors does mean more torque, but if you aren't reaching stall torque to begin with, what is the point of adding more torque? It doesn't improve anything in said situation.

It is quite easy to reach the limit of the electrical system, thus tripping breakers. More motors means lower current draw per motor since they are sharing the load.

Where was it mentioned that team 254 had breaker problems with the single CIM per side setup? Another thing I have never seen in FIRST although very possible. I remember back to 03 though, those drills would trip 40's regularly :D

Re: pic: Team 254 2006 Robot 1
 

While they didn't mention it, I can't see how they wouldn't. With a high gear of 15 fps and a COF of probably 1.1 or 1.2, and a stall current of over 100 amps, it would be next to impossible to not trip a breaker. Perhaps if you never encountered an obstacle. But as soon as you came up against another robot. Low gear will help, but it still may be possibel to trip it. I don't know. I could runt he numbers but I have no immediate desire to because more is merrier when it comes to motors.

Re: pic: Team 254 2006 Robot 1
 

Sure it would, 15 fps is outrageous for one CIM/ side to handle well. But when we are talking about pushing and low gear, I hold my claims to be true.

Amazing machine, guys...makes me want to come out of retirement ;)

Good luck this season, and I'll be at SVR to see this monster in person.

Timmy: Mama, Mama. I want a blue one!
Mama: No Timmy. You can only have a red one.

;)

is there video???

Re: pic: Team 254 2006 Robot 1
 

Dave - sometimes you are just SOOOO picky, picky, picky...

I'd be happy to have one in red, black, blue or whatever! But why settle for just one - let's make it two (or three, or four...)!

Re: pic: Team 254 2006 Robot 1
 

I've always liked the blue... But red will do too, if that's your thing.

Re: pic: Team 254 2006 Robot 1
 

Hmmmm, interesting...so is that the 968 bot?

Re: pic: Team 254 2006 Robot 1
 

In continuing with our mission of upholding the ideals of FIRST, we’ve entered this season in partnership with team 968. This year’s design is the product of many sleepless nights, late night phone calls, and swapping parts between LA and San Jose.

This is the third consecutive year that we’ve co-designed and co-built a robot with another team. Each year has been a unique and rewarding experience.

We would have broken the news to everyone sooner, but running the team has been a new experience for Cory, Bill, and I. Keeping our lives and the team together was much harder than we all expected.

Good luck to everyone and if your going to SVR and/or Nationals Stop by our pits to say hi.
