Wow that looks really really cool, looks like 25 has done it again.

What I like about team 25 is, they are using same (almost) chassis again. They perfect their chassis each year, and each year I get more curious to see their robot dominate at the competition. If you guys can I would like to know, how do you guys using this with what I see in the picture on this thread.

Look at the other picture Arefin- the hole the module is entering is the hole you see in the wheels picture in the plate near the end. The gears intermesh.

Actually- the chassi design is similar but this is the first year we are using the extruded aluminum product. We want to see whether it will survive the banging we tend to give it.

Why did you choose an extrusion this year? Your chassis seemed succesful last year and it does not look like you guys are short on the resources it takes for a custom cut chassis.

Every year we try to make our chasis as simple as possible.

Actually we try new things each year and we ARE a bit short on shop power this year. We saw 1089 successfully use the material last year and we thought it would be something to try out. Personally I like the tubular aluminum with nylon connectors we used in 2002 best but it wasn't my call. Lets face it- any kids with a hack saw can cut and connect the extruded stuff.

I like how you isolated the precision components (side plates for gears) from the less precision stuff (the main structure). I thought it was kind of a bad idea how your gearbox was esstentially the side of your robot last year (at least thats what I remember.)

looking really good.. keep up with the good work in perfecting a component, that's always fun to do and it's a real accomplishment. good job!! i hope everything else works out great too..just be careful who you let use a hack saw...some are better than others as i've learned.

We had a similar setup last year. Very similar, just different gear ratios and no extruded aluminum.

I agree on that one to, 25 has been a great bot when it comes to pushing and forcing. I love to watch them be able to handle them selves on the field. except for when they are handling them selves against my team.
I cant wait to see you guys in action again this year, its always fun to be around 25 and there evil machines,
is it going to be another evil machine name? i was just wondering

haha.. We are extremely sorry for PARC. I guess a rookie drive team with such a powerful bot is not a good combination. We did learn as the season went on, ofcourse with those mistakes.

Another evil machine name - no. I think we'll leave this new bot upto you guys to name once you see it.

So when do we get to see whats on top? We all know your drivetrain is gonna have the awesomeness it has always had, but your arms are the interesting part. Like maybe that enormous ~20 foot arm you had a few years ago....

Looks good. Is torsional stress a concern at all with so many close holes? Also, how much does that arm weigh (and what does this weight include).
