Robot slides to the left or right

[Krodeon]

As it says, when I create a Linkage(Klann Linkage in this case). I put it on the ground and the linkage seems to "vibrate" and slides slowly to the left and sometimes "bounces" into the air and is lost forever until I undo. Any idea what went wrong?

Please post scene file or link to it so we could see what's wrong and fix it...

[The Linkage]

What you probably did wrong was leave the collision layers on for everything. Imagine two objects overlapped... when two objects have the same collision layer, are overlapped and are not jointed directly between the two with an axle, they try to separate themselves by exerting a massive force. Select your Klann and go to collision layers -> No self collision. If that does not fix it then post the scene
