HEUREKA !!! I think i've got a solution to the problem, it includes a couple of spur gears at some thinking out the box so to speak. Will se i can put some pictures up tomorrow. Now back to brainstorming !!!

:wub: BRAVO !!!! Well done..

If you carefully look at the lower drawing you can see how i want the legs to be driven. ignore the two parallel axles for now, i would like to know how to make them shift side like this . ----A--I B I --A---- I I I I ----B I --A-I B---- And again from B to B to B. Widthout the axels interferring each other.

Any ideas on how to make at transmission that shifts from side A to A and then back to A ? and the same for the B side . Also it can't be wider than three studs...

Well. I have got another question, I have made a simple drawing of the geartrain of my walker. The upper one is how the legs are driven for now, i want to see how i can achieve the legs to be driven like the lower one. The drive axle are only three studs wide, so do any of you how to do this without the drive axles interfering with each others ???

WOW ! what a great looking bulldozer Jorgeopesi.

okay. thanks. blackbird.

Yes for this version i am. Only one M motor for driving and another for the shifter. But the next version i use a XL motor for driving it and a M motor for the direction shifter and a M liniear actuator.

Okay thanks. Will see what i can do. Here they are. http://www.mocpages.com/moc.php/371000 How do i make a direct picture link from this page ???

I don't know yet. Hmm.. it looks like i am not able to upload more pictures. How do i increase my picture upload ? I have only 45.23 K left !!

Hello efferman. I'm already using it in my new walker to make it turn like a bulldozer. when the A & B axels turn the same way the legs on each side walks forward or backward. But when they turn opposit the legs walk forward and backwards at the same time making it turn. I will see if i can upload a picture to better explain how it works.

I have also uploaded a Youtube video of Cyberbug mark I .. This version was a test platform, it can't turn left or right. It only walks forward or backwards. Feel free to comment .

This is my direction shifter that I'm using on my walker, this is of course only a mockup. But is shows the basic princibel .. As you can se on the picture it uses a simple changeover catch to chose from either the A or B output should turn the same way or oposit from each other.

Great moc ! Like it alot.

Hello everybody ! I'm new to this forum, but have been following it for some years now. I have some questions about a six legged walker that i am building. It's now on it's 3. revision. I'm trying to get it to turn but it's struggels when it's turning left or right. I have build a gearbox that can change direction on the two drive axels, that drives the legs, three on each side. But somehow it's almost brings my XL motor to it's knees and almost destroying it self !! So what am i doing wrong ? Would like to put up some pictures, but have to wait until i have made some more posts.
