Why would this be a matter ?

-#1 classic remote control, channel 1, you use lever right and left for two motors 

-#2 proportional train remote control, channel 2, you use only the left one for lights

-#3 classic remote control, channel 2, you use only the right lever for a motor

 

-Two receptors, channel 1 and 2

You would think that that would work, but I believe that if you try it in practice, it doesn't work that way. For example, if you used the left control on channel 2 to set the lights on the train controller, and then hit the right lever on channel two on the normal remote control, the lights will go out, even though you haven't touched the left control. Essentially, the receiver is only able to receive commands from one type of remote at a time, and switching back and forth will override the other one.

Looks really good and I like the technical dedication for this walking but it’s probably good you can’t photo in snow as it might sink with no feet??

I thought about adding discs as feet but I think it’ll spoil the look. Perhaps it’s just for exploring the frozen ice shelves and not fresh snow areas

Oh, I did not know about that, thank you.

I really like your walking mechanism, I think I am going to copy it and try it myself. Do you think, it would be possible to use it without the worm gears in a smaller moc or does this kind of movement lead to a lot of resistance which has to be geared down so much?

Best Regards

You’re welcome to the Stud.io file once I’ve finished it. The reason I used worn gears is that the 3D printed model I found on YouTube used a single worm thread to drive all the legs via a single motor. The other advantage with using a worm gear as the drive is it then locks the legs in place securely. The hardest part is making sure you react the loads from the legs into the body.

Great job on finishing your entry. It turned out great.

Thanks. There’s room for improvement (isn’t there always) but I’m happy enough with the model I’ve created.

@n8walker I’ve spent a bit of free time today playing with how small I can get the mechanism. Firstly I returned it to a single drive so it’ll go forward and back but not turn. The model I used as reference had this too.

Then changing to the smaller non bevel gears and also the 3l worn gear I get this.

so I think you could have a 11 wide chassis instead of 21 (excluding legs) so almost half size. But as I said this will only for forward and back.

i don’t think reducing the height of the mechanism is going to be easy though as you need to securely lock the gears in place so they don’t skip on the worm gear. The stuff above to move and support the legs can’t be shrunk much from my original model, but I’ll try and remove at least one stud in height.

Leg geometry might be interesting as the drive point and support are closer by a stud so not sure how well that’ll work.

ill have a further plat at some point as curious as to how this ends up

This is the second model that fits the sprit of the contest in my opinion.

Would have kill to buy this in the 90'

Well done!
