Quadruped Robotics

"Dynabot" is the name of the quadrupedal robot series developed by the laboratory. These robots serve as research platforms aimed at pushing the boundaries of technological knowledge in this promising field of robotic locomotion.

Mobile robotics has numerous applications today, spanning industries, search and rescue operations, space exploration, and more. In particular, terrestrial robots have gained significant popularity, especially those employing wheeled locomotion.

However, in certain applications, traversing more challenging terrains is necessary. While there are adaptations that allow wheeled robots to cope with many of these scenarios, this method of locomotion isn't suitable for a significant number of applications. For instance, in a search and rescue scenario where the robot needs to navigate through rocky or debris-filled paths, wheeled vehicles lack the required versatility. Even in many environments where such vehicles are currently used, modifying the environment is necessary. This is the case in offices or warehouses with stairs or uneven terrain that pose challenges for wheeled robots.

Our first quadruped is based on the open-source project SpotMicroAI, with some modifications that enhance its robustness and enable it to carry a more powerful computer. We have also changed the available sensor suite. On this platform, we are conducting research to enhance stability during locomotion, specifically focusing on improving predefined gaits modulated by a Reinforcement Learning-trained agent.

A custom-designed quadruped inspired by the "Cheetah 3" and "ODRI" designs. 
Created to offer maximum flexibility as a research platform without compromising performance, while maintaining a simple and low-cost manufacturing approach. Once design iterations and initial prototyping are completed, the project will be released as an open-source design. Currently, the performance of the quadruped leg design has been evaluated, and production of the first complete robot prototype will begin shortly.
