1678 robot cart

Can we get the cad of the beast of a robot cart that 1678 has. The water bottle holders makes it the best cart ever.


Why not just email them?


Damn. I’m stupid

I dont understand why you need CAD. It’s a pretty standard good robot cart with waterbottle holders that you can buy from amazon screwed into it, not a complex intake where you need precise measurements down to the thousandth of an inch to make it work.


That’s the old one. And also the water bottle holder was custom and holds a specific bottle.
The new one is actually a copy of 1323’s cart.

The new one is so cool. We finally got our CNC hooked up and we are gonna try to make a cart. So yeah that’s why I asked

I just picked up 4 of these for our extruded-aluminium-profile cart

for 3 dollars I can’t make anything that good.
EDIT: They were on sale last week for 3 dollars, I must have gotten the last set. Not quite the same value at $10

Sorry for the delayed response, better late then never I guess!

Here’s the link to our robot cart CAD: https://cad.onshape.com/documents/74412fc82decefad7d8d9645/w/1329657dcacebc44005717e0/e/cb280d421ea71269c4d04d1d

Hey we’re interested in building our own version of your cart, but had some questions:

What is the bottom plate made out of?

Did y’all weld the tube handle on?

What are the fork looking things for and are those plastic or metal?

The bottom plate is made out of plywood.

That is correct, the handle is welded on.

The forks are for holding drive team water bottles, and we made the part out of 6061 aluminum.

Let me know if you have any other questions, and good luck with your robot cart!

Amazing CAD organization!

Can you explain your naming conventions and how part numbers are generated?

Honestly we should start a thread about our parts tracking system or at least a link to anything we have on it. @nmcallister @Michael_Corsetto


Looks like the 254 system to me, but with “RobotCart” in place of the year because it isn’t year-specific.


This is correct. We just use 254’s system. Along with most everything else we do besides the whole “blue” thing.


So by trying to copy 1678, we’re really just playing telephone with 254.


Aren’t we all just trying to copy 254? :stuck_out_tongue:


This is the greatest link I’ve ever seen. Thanks!

Not to be the “one-up” guy, but this one is better.

I was talking about the part numbering because we need a system for it, but wow, some of the recourses out there… Thanks for the link!

Do you happen to know where you ordered the casters from? It looks like it’s a Colson Caster wheel part 4.04109.449 BRK4 but I can’t seem to find a distributor online.
