I recently combined an EV3 with a 42006 Excavator to make it fully remote controllabe. I put together a video of it in action:

Here is a blog post I did on it with links to the instructions and EV3 code:

It was a lot of fun but figuring out how to build a motor multiplexer small enough to fit in there was tough.

Hi,

Well done! I like it a lot.

Nice work on the multiplexer too

Heh you beat me to it, I was planning the same thing. But yours is remote controlled, I want to build one that picks up trash from the floor autonomously :) The runfirst program is an interesting approach, I hadn't discovered that option yet to "remember" motor positions.

"The claw, it chooses." Good work on the multiplexer.

That's really cool!

Thanks! As soon as I had the idea I knew that alien from toy story would have to be the picked up :)

I went through a couple of different approaches on the multiplexer. The other one I tried was cool because it would let you turn on two outputs at once but it was just too big.

Great work including new parts!

Nice work!
