Alright, I am going to try to answer everyone’s questions…

… wrong.

We will be going up any ramp that is less than 20 degrees.

Thanks for your comment Tim. I personally think there will be many other robots that will have pushing power just like this one. If the rule didn’t stop us, we would probably move the goal. =)

I don’t know if I would say overbuilt. It’s was very easy to work with. Thanks to my Canadian friends who gave me this idea to use 4x4 for chassis material.

What material is the plate on the bottom.

David G.

It’s 1/16” lexan.

Is it going to collapse? Doesn’t look like it, but it can in a brutal fight in the field. It’s better to add support than being left without a chassis in the middle of the competition. The way the two modules are connected are with the C channels. On the bottom, I am running 1” wide 1/8” thick aluminum across to support the chassis. On top of that… the lexan is mounted (it is mounted on the C channel and the crossbars I am running underneath the chassis).

… we will be picking up robot/robots off the ground 12”.

• Live or Dead Axles?
• Are your axles running on bushings or bearings?
• What is your base plate? Wood?

Keep up the great work 1345!

1) It’s 28 tooth.
2) Dead axles.
3) There are bearings on the wheels.
4) There is no such thing as “base plate” on this chassis. Electronics are mounted on a 1/16” lexan which is mounted on the crossbars and C channels.

Thanks Conor, looking forward to see your robot in action this season. Tytus’s chassis looks great. His chassis looks unstoppable just like it was in 2005, I only hope his driver can drive that thing.

All the wheels are powered. There is single chain running each module. Video will be posted soon.

ps - please volunteer for the iri so i can make you in charge of cleaning up trash as punishment for poor behavior.



(cool chassis, anyway)

pictures can be decieving. There are no extra tubing in that chassis. It looks that way, because most of the stuff weren't zip tied down well enough. The electrical board needs a lot of work. It will be clean once the whole robot is together. Your inspectors won’t have any trouble inspecting that thing, since we are talking about making our way up to Indiana this summer.

Volunteer? Hmm… we shall see. It all depends on if team is going up there or not or if I am taking classes over the summer or not.
