Team 4183 Bit Buckets prototype hook
 

Today our team came up with an interesting idea for a way to pick up/ store totes and so here is our first prototype of this idea.

This is a pretty neat idea and I don't even need to zoom in to see the details!

Re: Team 4183 Bit Buckets prototype hook
 

This looks nice. Great job!

Re: Team 4183 Bit Buckets prototype hook
 

Nice hook. It looks like it can only lift one tote at a time though. Have you tried putting a hook on either side?

Re: Team 4183 Bit Buckets prototype hook
 

The hook can hold several totes, but it was intended for one at a time. We have not played with using multiple hooks per tote yet, but that is the approach we're most likely to take.

Re: Team 4183 Bit Buckets prototype hook
 

Okay. The tote in the video looked very crooked.

Re: Team 4183 Bit Buckets prototype hook
 

One of the Ri3D robots noted that picking up multiple totes with a single hook would eventually cause damage to the bottom tote. Start at 0:45 - https://www.youtube.com/watch?v=wa6wvzM2naA

Nice Hook Design....

Now .... can you design it so that it can sit on top of 5 just like it, all connected by chain / rope / wire, that can be indexed up as you pick up 5 totes? Gravity will unload you and bring the clips back to the bottom for another run...

Re: Team 4183 Bit Buckets prototype hook
 

That's our plan for today.

Re: Team 4183 Bit Buckets prototype hook
 

Very cool design!!

This was something that we considered, but ultimately ruled out because of strength concerns of the totes, and lining up was an issue.

Re: Team 4183 Bit Buckets prototype hook
 

Took this idea and ran with it. It's not a standalone hook, rather additional stuff will be mounted on the front. Hoping to build it tomorrow.

Re: Team 4183 Bit Buckets prototype hook
 

Are you going to add mounting holes on the flats?
How are you going to cut the wood into that shape? Are there slots I can't see?
Neat design. I like the modularity.

Re: Team 4183 Bit Buckets prototype hook
 

Very Nice Rendering.

Have you considered making the triangular part on the back of the clip a little larger, perhaps twice the size? If you add holes along the bottom backside of the clip ( with a bit larger triangle... ) you could adjust the angle of the front face of the clip by simply moving a the bottom connecting pins to new locations.

Just in case you new assembly's added to the front of the clip need angle tweaking.

I have to learn to cad better. Good luck.

Re: Team 4183 Bit Buckets prototype hook
 

The mounting holes are going to be hand drilled, this is just for prototyping. The wood is laser cut, just like 4183's design. The darker surfaces are the laser cut edges, and you can see that there are a few pieces inside intended to keep everything square.

I probably could have done that, but I made this model in a couple of hours to fit around the wood we already have, and I have to laser cut this right now before our next meeting. I'll keep that in mind for the next iteration.

Re: Team 4183 Bit Buckets prototype hook
 

My god, if you guys can make a multi-hook system that would be awesome, because i was proposing a very similar idea, but we opted out for a simpler design than mine, so it would be awesome to see another team make my dream design come true!

Re: Team 4183 Bit Buckets prototype hook
 

We're working on it!

Re: Team 4183 Bit Buckets prototype hook
 

That is a really ingenious design. However, I'm trying to figure out if is possible to set down totes over an existing stack. Will the hooks swing up and over the handles when moving downwards?

Re: Team 4183 Bit Buckets prototype hook
 

We've been working on this concept a bit.

Re: Team 4183 Bit Buckets prototype hook
 

We chose to go with something similar. Very exciting to see how effectively you have implemented it!

Re: Team 4183 Bit Buckets prototype hook
 

I'm gonna have to make a trip up to Tucson tomorrow, to see that in person!

(and watch the movie again)
