  • Map-independent Online Generation of Alternate Paths for fast local planning
    • In this work, I develop a local planning algorithm based on VFH+ for fast local planning.
    • [Code]          [Blog Post]               [Video]
  • Object picker module for Cartbot
    • Andrew Sack, Jonathan Chang, James Liao and myself built an object-picker mechanism to be attached to  Cartbot. The purpose of this attachment is to enable Cartbot to pick arbitrary objects from the ground and put them on a higher platform like a table or to transfer objects between surfaces of different heights.

  • Voice-Controlled Fridge for Assistive Robotics Applications
    • In this work by Chenlu Wu and I, we develop actuation mechanism and voice-control module for opening and closing a fridge. The goal for this work is to enable people with physical disabilities to use the fridge. Future work would focus on enabling such people to take food from the fridge

  • Creating Cartbot: The 3 DOF mobile-manipulator robot
    • In this work, Prof. William Messner (PI), Kentaro Barhydt (PhD Candidate) and I work on converting a shopping cart into a mobile robot base for the RASCAPP robot.

  • Building RASCAPP: A mobile-manipulator Domestic Assistant robot
    • In this work, we build a mobile manipulator robot whose main purpose is to provide domestic assistance in homes.
    • [Paper]                 [Video]                 [Code]
  • Robot ‘learns’ drink pouring skills
    • In this post, I describe how I got RASCAPP, our mobile manipulator robot (basically Baxter on an electric wheelchair) to perform drink-pouring tasks. I also deliberate on the bigger picture; how to balance learning vs planning in domestic assistant mobile manipulator robots.

  • Implementing the classic bug algorithms in simulation and on real-life robot
    • In this post, I describe the bug algorithms, my implementation details of this algorithm in a gazebo simulator and on Cartbot, a real-life robot.
    • [Blog Post]
  • Self-adaptive whole-body manipulation for correcting failed robot grasps
    • In this work, I deliberate, propose and implement a novel approach by which mobile manipulator robots can re-adjust their entire bodies to increase the chances of successfully grasping an object after a failed grasp attempt.

  • Setting up SLAM on RASCAPP robot
    • In this work, I set up both the hardware and software systems necessary to get our mobile manipulator robot, RASCAPP, perform Simultaneous Localization and Mapping (SLAM) in the lab.
