Beebot

🔗 Source Code

This open-source project transforms a basic mobile robot into a fully autonomous system capable of navigating environments, avoiding obstacles, and executing tasks independently—without any human intervention. As a personal project, it was developed with the goal of building a complete autonomous robot stack from the ground up. The purpose was to create a practical platform for testing and validating various algorithms in real-world conditions. Through this project, I was able to integrate and experiment with key robotics modules in a realistic setting, accelerating development and deepening my understanding of autonomous systems beyond simulation environments.

Human-Robot Teleoperation (HRT)

Human-Robot Teleoperation (HRT) image

Human-Robot Teleoperation (HRT) is the focus of my Ph.D. thesis project, developed using MATLAB and supported by a series of published research works. It aims to establish a reliable and responsive teleoperation framework that balances both human control and robotic autonomy. The project addresses four key aspects:

  • Robustness: Stable performance despite uncertainties from the operator, environment, or sensors.
  • Performance: Effective task execution with speed and accuracy.
  • Perception: Enhancing the operator’s awareness of the remote environment.
  • Transparency: Accurately reflecting the environment and robot state to the operator. To find further details in my thesis defense presentation available in the Education section.

Variable Stiffness Actuator (VSA)

Variable Stiffness Actuator (VSA) image

This project designs and controls a Variable Stiffness Actuator (VSA) for quadruped robot legs to enhance adaptability, shock absorption, and energy efficiency. The VSA consists of two actuators: one controls joint position, the other adjusts stiffness by modulating an elastic element. This allows real-time tuning of joint compliance independently from position. The control system includes:

  • A high-level controller that plans motion and desired forces,
  • A low-level controller that adjusts both position and stiffness using sensor feedback. By integrating VSA into each leg, the robot can achieve softer landings, better stability on uneven terrain, and improved safety when interacting with humans. This approach mimics animal-like locomotion and is ideal for dynamic and unpredictable environments.
