Spectrum's Cart for 2014
 

This is the design for the cart we will be using next year. It will be laser cut with 1/8 inch aluminum.

Thanks to team 148 for helping to inspire the design by sharing the CAD file of their Cart.

Looks pretty cool. How is the robot going to stay on? Just the weight of it?

Re: Spectrum's Cart for 2014
 

There are mounting holes in the top plate that we can mount support blocks into for the robot. It's designed to be customizable for different robots. They will probably just be wooden blocks.

Edit: Ninja'd
I assume that shocks will be bolted in after the frame of their next bot is finalized.

Is there a small lip around the edge of the faceplates at all?
Also i was kinda hoping that casters would mount in the corners with a 1 inch drop and make it look like a hover cart. Purple underglow?

Re: Spectrum's Cart for 2014
 

No wheels? It must be a hovercart.

:rolleyes:

Re: Spectrum's Cart for 2014
 

We were wondering who was going to be the first person to make that joke. There are holes for the wheels to mount. Ryan just didn't CAD the wheels since we are just using the ones off our previous cart.

If anyone is wondering we use two of these in the back and two of the non-swivel ones in the front.

I want to make a powered robot cart with mechanum. I think that it would be really easy to maneuver. Our Logomotion robot has mechanum and I love moving it because it can move sideways, making it easy to push in tight spaces. Have you considered this?

Re: Spectrum's Cart for 2014
 

Mecanum's only work on flat surfaces, so it will wreak havoc whenever even one wheel is off the ground (which is common in carts). Even if you have some kind of suspension system, I wouldn't trust it.

Although powered omnis could be fun :P

Re: Spectrum's Cart for 2014
 

I'm just really hoping for a cart reveal video when this is completed.

Re: Spectrum's Cart for 2014
 

With lots of dubstep and an underglow.

Re: Spectrum's Cart for 2014
 

Robotics = Dubstep nowadays. ^^

A purple underglow would be pretty cool. Make sure the blocks you put on top are tall enough for you to work on the robot comfortably!

Anyone have the link to 148's cart CAD?

Laser cut? Aluminum? You must have a powerful laser cutter.

Re: Spectrum's Cart for 2014
 

The top surface of our cart is a mirror so that we can see under the robot.

Re: Spectrum's Cart for 2014
 

We have a sponsor (Solarcraft) that will cut out the parts for us.

I emailed JVN to be able to see their cart CAD. I imagine if you ask him he will be happy to send you it.

Re: Spectrum's Cart for 2014
 

This is one of the best ideas I've ever heard. How do you protect the glass from impact damage?

Re: Spectrum's Cart for 2014
 

I'm not too entirely sure, someone else on my team would answer that question better. I think it's either a polycarbonate mirror, or a piece of clear plastic is placed over the mirror. I think it's just a polycarbonate mirror, though.

Re: Spectrum's Cart for 2014
 

I remember that some team made a release video for their cart a couple of years ago. It was pretty epic. I think the cart was motorized too...

Here's the song for it:

Re: Spectrum's Cart for 2014
 

It's taken a bit longer than we thought to get everything together. We just got the parts back from the laser today.

We might not have them powder coated in time for IRI and TRR.

Re: Spectrum's Cart for 2014
 

Wow.

With all honesty, I think it'd be a masterpiece without the powder coating. But it will be with the powder coating too :)

Re: Spectrum's Cart for 2014
 

I would really like to just use this design entirely for my teams cart too :p I think we are going to come up with some cart plans though here in the fall. Although this is the most epic looking cart I have seen. It's just so clean.

Re: Spectrum's Cart for 2014
 

Sadly it won't be Powder Coated for IRI or TRR but hopefully by Red Stick Rumble.

Re: Spectrum's Cart for 2014
 

It looks great as is without the powdercoat. The bare metal may look better than the powder coat after a few years of hard use.

You may want to add a bit of triangulation where the handles protrude from the top deck to prevent the square tubes from bending there when someone tries to push the cart over a bump in the floor a bunch of times.

Re: Spectrum's Cart for 2014
 

Dude... you can cut 1/2 steel with a laser. Why would aluminum be a big deal? They're not using a little laser engraver. Metal cutting lasers are very common not to mention one of the best options for cutting out robot parts.
