Manipulator Control


I envision a future where robots can work collaboratively with humans for enhanced safety and productivity. To make this a reality, I research intuitive control systems that are adaptable to any kind of robot with a recent focus on robotic arms.

I work with many different systems, ranging from industrial arms usually kept in cages to "cobots" that are designed with human interaction in mind.

The robot below, "Herbie", is a serial chain of 6 series elastic actuators with a camera at the end for inspection tasks. While another student in the Nuclear Robotics Group designed the robot, I refactored the control code to make it more modular.

Note that the controller has been improved to produce much smoother motion than in the footage above. I also helped integrate Herbie on to a mobile robot base. Planning and execution is done with MoveIt, an open-source manipulator control package.

The bulk of my grad school research now centers around a novel passively-balanced manipulator, Scorpio.
