 This repo contains the quadruped controller used at DFKI's underactuated lab.
 It mainly contains a *simulation*, dynamic walking controller using *MPC*, *WBC* and different *Gait Sequencers* and hardware *drivers* to be used with different quadrupeds.
 - To install the whole software stack please refer to [Installation](#installation)
