Currently I am working on a model 11-86. But I cant figure out how to make a balanced and well animated bipedal mechanism. If you can help you will receive 5 upvotes on your own posts. But the model isn't finished yet. I will tag you in a unlisted version, and once you finish re-upload it as unlisted too. Please only offer your help if you have experience with it. Nothing personal I'm just putting a lot of time Into this.

Last but not least first two offers can offer their own version. The best gets 5 and the other will receive 3 upvotes. Thank you in advance and be sure to keep an eye out for that Tag. Happy Engineering!
