Title: Chassis
Post by: Zach G on January 16, 2016, 04:38:45 PM
The Chassis the base frame of a Robot

1/14/16 -- 15/16 Made a mock Chassis with wheels.
1/16/16 Made CAD design and looked at parts

We made progress on building the chassis from parts we had in the CAD Dropbox and from parts online.  We have the pneumatic wheels already in the drawing, it's just a matter of putting the rest of it together.  There is already a completed version of what the chassis should look like on the AndyMark website.  We just need to make our own assembly so we can modify it to our liking.

We are missing a few pieces. We will have to make them ourselves.

Continued working on the chassis. They can be found on Wes' Dropbox.  Wheels are in, pulleys are built but need to be assembled. Also, we need to assemble a lot of the bearings.  I'll be in Thursday to continue working on it.

Peace!

Works the best
less space between the wheels. questioning front end
little mor room and the Wheels are mor in front. does get traped on a few thingsToo spread apart
Gets stuck
Not using
very little help at all. Maybe for rock wall but gets stuck on other things like rough terrain.

Tried to make a table on this forum but had a Hard time and this is what it created

--- 1/26/16 Update. I've taken the above content and made a table (Lou) --

We figured out how to easily make a CAD model of the chassis! We downloaded and collected all the necessary files, and now we have to finish putting it together.

SO I FINISHED THE WHEEL. so all the wheels are done, that is all

Finished countersinking the holes for the bolts on the underside of the chassis so we don't get stuck on anything.
Made the wooden frame for the bumpers and can easily cut pool noodles to the right length. Can't put any attachments on yet. Easier if we wait until all other teams are finalized with their designs so we can work around their stuff when screwing on mounting plates. Nothing else started for tomorrow.

Good idea waiting for the attachment points until the other systems are finalized. But having a temporary way to slip on the bumpers for quick eyeball checking could be useful

Assembling the Chassis currently. Peter says it should be finished tomorrow. Also, Kyle figured out how to make the intake arm in CAD.

Grinned another set of gears and put the original set back in the gear box
Started to put together the chassis but still need a few parts

Wonjae set up the first half of the chassis and we are trying to get the correct length for the churros.
the chassis is theoretically we just  need to put it together and fix Andymarks mistakes

We cut the remaining three churros and put one half together to see if everything was evenly spaced and if we needed to change the spacers at all. It looked like we would need to correct some issues regarding the width of the spacers on all three axles.

Basic frame Chassis parts are in and we have completed the chassis. We may need to change a few things in future.

Then shalt thou count to three, no moreľno less. Three shall be the number thou shalt count, and the number of the counting shall be three. Four shalt thou not count, neither count thou two, excepting that thou then proceed to three. Five is right out

CAD's next task is to animate the robot. It will take a while, considering how much time is takes to edit the assembly.
