Anyone know where to find clips

If you don't have those tools, you should try to get them, because they are pretty much essential to building a robot.

If you would like some advice about how to make the clips using those tools, let us know, we can help.

Agreed if we were making a few dozen. we are making about 64. The cutting part is doable. its the having to drill each hole 4 times to size and hold tolerance. That’s over 760 drilling sequences. I would rather have the kids work on something else if I can find the clips cheap enough.

As far as I know, you are not likely to find any angle brackets ready made to that specific size and hole layout. Usually when designing a mechanism, you either plan on how to make all the parts before you finalize the design, or you design around parts that you can buy.

There are some tricks to making parts with holes in the same place, you can make a drilling jig that supports the part in place, and has a hole for each hole you need to drill, that lets you just put the drill in and it automatically aligns it. You would (edit: might) want to drill the holes before bending the part, too.

It need not be fancy, just needs to do the job. Look around and see what you might make it out of.

Not specific size/layout you posted, but what about one of these?

Standard corner braces, one at 2 inches long, the other at 1.5. Generally speaking, any hardware store is going to carry some corner brackets (usually near the door knobs)... they may not be exactly what you need, but if you can make them work...

Yeah i made a bad assumption. I assumed simple clips would be easy to find with a 1" spacing between holes.

If we have to drill them your idea of a drill jig is awsome. That would make things go alot faster.

Thinking about it more, you probably want to make your drill jig so it works on a pre bent bracket, then you won't have to worry about bending it exactly right.

If you get the drill jig set up and working, please post a pic so we can see it. This is neat stuff, and helps out other teams

We are going to get that set up today so we should have some pictures in a few days.
