Rage has built their chassis out of wood for several years now. (At least as far back as 1999 I believe). They do a heck of a job, and prove to all of us "metal heads" that timber can be competitive too!

Fresh new robot pictures. One gear box with both Chip motors in them.

Raw power on both side of robot now.


still lots to come. Who said kids can't build a good robot with out engineers.

OK, I have just GOT TO KNOW how you are going to use the Whimhurst machine on your robot!!! I am thinking that you are building an electrostatic rail gun to launch the small balls from your opponent's end of the field straight into your own ball corral!

And don't even think of using the old "it just another non-robot project" excuse. :)

Very nice simple gearbox for those CIM's. Im always amazed at the pounding that your wooden robots take. I know what you showed us probably wasnt the final version, but you do know that you cannot use the 2002 CIM motors, right?

The non robot project is for VICA one of my fellow class mates will use that this year. It will produce around 18-24inch sparks so it will be pretty cool to watch when its fully done

Re: Team 61 2004 robot
 

Yeah we have quite a few wood bases from over the years and other random mechanisms just lying around our shop. I think the plywood goes back even further then 99' not sure though. We have a lot of pictures and I will go through them to see when it started if I can, but we also have a few people who were there when the team started 10 years ago so I will ask them too. Also we have only ever had one problem with the plywood breaking as far as I know and that was at last years UTC New England Regional. I will have to find a pic of it somewhere and post it up here if it isn't already. This is one of the bot while being fixed.
this is the other one

Re: Team 61 2004 robot
 

anyone remember these.....alll wooden bases

Re: Team 61 2004 robot
 

Wow! Thanks for posting your pictures!

It looks like you are driving one side of your treads with two paired Drills, and the other side with two paired CIMs. These combinations clearly yield different torques at the same speeds. How do you deal with that?

Also, as has been pointed out, FIRST did say that using the CIM motor with the geared output shaft and the coupling gear that came with the kit in 2002 is not legal this year... Just hope you are aware.

Best of luck!

Well we found out the hard way that the drills turn on earlier (i belive) then the CIM's. So what was happening was we would bend out shafts pretty bad so what we did was put the CIM's on one side and the drills on the other, there is a little difference but nothing our drivers can not fix. Also the only other difference is the CIM's roll after you let off the joy stick where the Drills stop right away.

All and all it worked very well for us last year and hope for the same this year.

Not sure about the coupling of the output shaft rule or what ever so I'm not even going to attempt to answer...

More pictures have been posted

check out our landing gear. We will be flying this year, more ways than one

O oh Mr. Norton we forgot the wings and the huge propeller.

Re: Team 61 2004 robot
 

everything looks great.. one quick question tho.. y not just run a CIM with a drill instead of 2 CIM's and 2 drills. That seems like it would be way to hard to get to balance out correctly, plus one side is driving in reverse.

Re: Team 61 2004 robot
 

Nope, did it last year and it ran GREAT!!

Re: Team 61 2004 robot
 

The robot looks great, but those CIMs are illegal.

The ruling this year is that motors have to be exactly the same as those provided in the kit to be used on the robot. The CIMs provided this year have an 8mm shaft with a 2mm keyway cut in them, as did the motors from 2003. When we got the original CIMs in 2002, they had a geared output with those pressed-metal mating gears, like those you have in the picture. However, they are no longer legal with this year's ruling.

Sorry to break it to you, but better to find out now than at a much worse time.

Re: Team 61 2004 robot
 

take a closer look at the new motors. We been in this game for ten years I hope we know the rules as well as others.
