500 ## - GENERAL NOTE
General note Quadrupedal robots have gained significant research interest due to their ability to<br/>achieve agile and stable locomotion over complex terrains. Such locomotion can be<br/>achieved by combining various gaits, however, simply changing robot gaits does not<br/>guarantee robust and stable behavior. To ensure stable robot locomotion, gaits must<br/>be seamlessly blended. Current methods of gait transition include model-based, mainly<br/>Model Predictive Control (MPC), approaches, which are limited by the use of handengineered gaits; Reinforcement Learning (RL)-based methods, which address these<br/>limitations but require extensive training; and hybrid methods that combine multiple<br/>controllers but still experience abrupt gait timing changes. This thesis introduces a<br/>novel RL-MPC hybrid control framework that addresses the controllers’ shortcomings<br/>in the current literature. The proposed controller incorporates a feature extractor module that extracts features from the robot terrain and state. The novel framework also<br/>introduces a gait timing correction step to smooth out gait transitions. The proposed<br/>framework was tested on a randomly generated rough terrain, where the robot efficiently traversed and transitioned between gaits while maintaining accurate command<br/>velocity. Testing the effectiveness of the contact timing correction step revealed that the<br/>locomotion produced by the controller without contact timing correction was jerky and<br/>unstable on rough terrain. The proposed framework also outperforms a state-of-the-art<br/>method in gait transitioning, resulting in smoother and more stable locomotion.
