I think you would be better changing those CV joints to universal joints. There does not seem like there is a lot for steering movement from using CV joints.

It's not very aerodynamic. I am guessing you focused on mechanics over style.

Great tank,I am looking forward to the video.

I am a operator,we start to slew around only when save to do so. When we use a excavator for stock piling we can control the excavators arm as well as slewing at the same time. We also use the the arm and the slew of the machine in aid of the excavator when tracking.

Here is the improved standard version. Here is a link to the high rise and HRD mod I did.

My modified excavator had eight motors because of the extra 2 functions I added.

Glad you sorted out your problem.

That is really cool.

There is no problem with the instructions,I have built it myself. I suggest you count the studs/holes on the bricks to see where you have gone wrong.

There may be room in the cab,the model is very compact so it may be tricky.

Add gearing.... Lego do already make a roar sound brick. Zblj your Dino is doing the moon walk.

I think you should try motorizing both front ones and rear ones independently. If you find that there is a bit off misalignment between legs, you could always gear it up/down to synchronize the legs.

For the bottom of the machine you should be using four (12) technic bricks and two (14) technic bricks.

Ah,yet another good use for a PF micro-motor.... What about steering the back legs as well as the front ones?

Does this count? I still have my unimog,a motorized 8256 loader,Jurgens backhoe,my moc tractor the scrap handler and the mini backhoe of this year still assembled.

You have all ready improved the steering a lot,but maybe if you still require more responsive steering then it could be a option. I am unsure what such a mechanism will do on the 'balancing side' of things.

Two more little suggestions: 1) What about using small LA's on each leg to increase the steering? 2)what about attaching some of the rubber connecters horizontal to the ground to stop the legs slipping.

Zblj's design will work,I also checked.

I think you are have turned up the speed just a little to fast...... Nice set up though.

+1 Tazzy007,a pleasure to deal with.

Try the new L motor,It is becoming one of the most favored Lego motors for moc builders.

If you gear three legs that are the same speed as each other,and then gear the last one differently (like what you said above) then will that not improve the steering of the walker?

Surly that is just down to gearing the legs differently?

I don't think a very small ill-alinement would matter?

What would happen if you power the front and back legs independently in a diagonal setup?
