I hope not...

*goes and starts to make numerous chassis in inventor/solidworks*

This bot was built using spare parts from FIRST's shop... It was only meant to be a sneak peak at the 2009 control system and in no way was meant to show what may or may not be in the KOP next year :)

So there may still be hope for the kit frame next year...

I'm not going to lie to you guys but the power block wire connectors are so strong that the people from Diversified Systems put batter wire on it and pulled a full size 120 lbs robot around without the wire pulling out. The wire was only a foot long, it was amazing.:eek:

Re: pic: 2009 Control System, Mounted

It's not the initial strength. It's the resistance to vibration. Since there's no WAY that thing could be any worse than the din rail (we zip tied the wires to ours so they wouldn't vibrate loose), then it has to be an improvement!

That long module has already been replaced by the half-size module that's sitting next to the PDB.

Actually, the DSC3 is less than 1/5th the size of DSC1.

How were the prototype white cases for the electronics components fabricated? They sort of look rapid-prototyped, but I am not sure, and didn't see them in person.

In fact, I could easily pull it out by simply wrapping it around my hand several times, giving it a few inches of slack and then yanking the giggles out of it. Unfortunately, I smacked my arm into the robot during said yanking. Ouch.

Don't count on those WAGOs on the PD as a structural element, but boy do I love them!

Re: pic: 2009 Control System, Mounted

although it is a lot bigger than the IFI control system, who says that FIRST isn't going to allow larger robots, or even heavier ones? i really think robot design wont be the same any more.

The robots are already about as large as they can be and still fit through a standard doorway. They are already about as heavy as they can be and still be carried safely by two high school students. I don't expect the size and weight limits to be increased. I wouldn't be surprised if the rules next year called for smaller robots.

A robot with a battery and bumpers mounted could be up to 120 + 12 + 15 = 147 lbs. At least, that's if I remember correctly, and the battery weights about 15 lbs. So I don't see much room to add weight, if we wish to remain within OSHA regulations.

I thought the distribution block/fuse block length was customizable, i dont wanna waste all that space that could be used for something else...
