Just wanted to showcase a project we (a couple of students from University of Applied Sciences Bielefeld) are currently working on. It is a continuous-track robot that is able to deform itself to a certain extent and thus, able to overcome obstacles or uneven terrain. The robot basically is built from out-of-the-box AX12-A servo drives with some 3-d printed encasings, which mainly exist to have something to place the sensors/boards on.
I´ll let the video speak for itself and if there are any questions, let me know and i´ll try to do my best to answer all of them:
If you´re interested in the mathemathics that run behind this, you can also take a look at the corresponding IEEE paper:
Thanks a lot for your interest!
