I am Atharva Ghotavadekar, an undergraduate student at BITS Pilani majoring in Electronics and Instrumentation Engineering. My research interests lie in the intersection of perception and control for mobile robots, including perception aware control. I find the application of learning based methods in real world robots a really exciting problem. The fact that we are getting closer to realizing human-like behaviour, and even better, on cyberphysical systems, is my primary motivation behind pursuing robotics.

I have a solid hold of programming in Python, C, C++ with OOP. Apart from programming, I have a good hold of simulation software and multiple frameworks for robotics such as ROS, Gazebo, Matlab, Simulink, etc. I also have a good amount of experience in hardware implementation, including Motion Capture Systems, multiple ground robots and quadrotors, UWB-based RTLS, etc. I have worked on research projects at Research Labs, Educational Institutions, Competetive Teams and Student run Groups. This has helped me to apply my knowledge in different scenarios and gain hands on experience in robotics.


I have worked at the Robotics Research Center at IIIT-Hyderabad on navigation of MAVs in GPS-denied constrained environments under the guidance of Dr. Harikumar Kandath. During my three-month stay, I also had fruitful interactions with multiple researchers, including professors, graduate and Ph.D. students. This enabled me to imagine better how the life of a researcher might be, and it deeply resonated with me. This experience heavily reinforced my inclination toward pursuing robotics research in the long term. I also worked in a shared space with a Ph.D. student working on a novel payload-agnostic UAV startup. Through our discussions, I gained valuable insights into the distinction between research and industrial product development and how the two are linked yet significantly different.


I am also the Chief Coordinator of the Electronics and Robotics Club of our campus. This role involves being the primary point of contact for interactions with professors, representatives from multiple industrial companies, and 200+ students at project displays.


I am an avid cricket and basketball enthusiast, and spend my free time in the evenings on the court. Apart from that, I am deeply interested in Indian as well as Western philosophy, so do reach out for a long discussion anytime :)

Feel free to check out my CV and drop me an e-mail if you want to chat with me!

Research Intern | Robotics Research Center, IIIT-Hyderabad
June '22 - Aug '22

  • Developed algorithms for navigation of a MAV in cluttered GPS-denied indoor environments
  • Worked with a UWB-based Real Time Location System for fusion with IMU for state estimation

Chief Coordinator | Electronics and Robotics Club, BITS Goa
May '22 - present

  • Leading a team of 50+ undergraduate students working on multiple technical projects across domains in robotics including ground robots, legged robots, swarms robots, robotic manipulators, etc.
  • Responsible for managing funding from multiple sources, organizing discussion sessions, display events, media and outreach of the club

Controls Engineer | Project Kratos
July '21 - present


Trotbot

Code

  • Developed a ROS Action based interface for motion planning, dynamic obstacle avoidance and replanning for an omni-directional ground robot.
  • Worked on implementing obstacle avoidance and a low level controller for an omni-wheeled robot and integrating an A* planner with 2D Occupancy Grid.
  • Currently working on obtaining reliable odometry for performing indoor visual inertial SLAM.
  • Geometric Path Tracking ”Stanley” Controller

    Code

  • Implemented a path tracking controller for traversal of smooth continuous curved trajectories
  • The controller tracks the closest point on the desired trajectory uses lateral error from the target point (crosstrack error) as well as heading error to compute the control output
  • The Stanley controller was implemented on Project Kratos’ Mars Rover
  • Spiderbot

    Code

  • Spiderbot is a custom designed and manufactured symmetrical hexapod with each leg having 3DoF
  • Working on implementation of various gait patterns using a bio-inspired Central Pattern Generator(CPG) based controller for smooth motion.
  • Strikebot

    Code

  • Strikebot is a spherical ground robot controlled by an internal pendulum and DC motors
  • Interfaced with an IMU (MPU 6050 and MPU 9250) to achieve active damping for stabilizing the spherical robot
  • The project was displayed at Quark 2022, the annual Technical Fest of BITS Goa.
  • ROS Hackathon

    Code

  • Developed a software stack for an omni-wheeled ground robot to traverse through a field of obstacles autonomously
  • Motion planning uses a modified variant of RRT for path planning and closed loop PID control for point to point navigation
  • The submission was made to a hackathon in my sophomore year.


  •  Coming soon :)
