Creating robots to build structures in space In-space assembly by robots can transform how structures are built in space, enabling larger habitats, space telescopes, col- located Earth science instruments, and backbones for scientific and commercial use. Assistant Professor Komendera, director of the Field and Space Experimental Robotics Laboratory, has led research in ISA as a NASA researcher and as assistant professor. In August 2019, NASA awarded a two-year, $2,500,000 Early Career Initiative grant to Langley Research Center, Virginia Tech, and Honeybee Robotics, for “Assemblers: A modular and recon- figurable manipulation system for autonomous in-space assem- bly.” The project will apply advances in machine learning, control theory, and state estimation to expand concepts pioneered by Komendera and others at NASA. Assemblers will develop and demonstrate a lightweight, highly stiff assembly manipulation system consisting of stacked Stewart platforms, and a multi- agent task management system to manage in-space and surface construction tasks. Assemblers will be a modular architecture featuring interchangeable end-effectors for the multiple tasks required to construct complex space systems. Assemblers will also implement methods for error detection and correction using machine learning and autonomous decision-making. Erik Komendera Assistant Professor Research Focus: Autonomous assembly and construction; Space robotics; Field robotics; and Perception; Robotics to improve quality of life Alexander Leonessa Professor Research Focus: Control theory and robotics; Autonomous ground, aerial, surface, and underwater ve- hicles; Rehabili- tation robotics, brain computer interfaces, and sensory-motor neuroprosthesis Dr. Leonessa’s research focuses on the design, control and validation of robotic solu- tions to improve the quality of life of people with disabilities. His research spans from functional electrical stimulation to help people with paralysis, to prosthetics design, and brain computer stimulation. Over the last few years his research has mainly focused on the design of exoskeletons to aid farmers, manufacturing workers, first responders, and people with spinal cord injuries to regain the ability to complete their daily tasks.
