Bridging the Gap in Space Robotics: Conclusions

RSS 2017

2 of 4

Summary

  • How will these algorithms scale up? It seems some of them may, through lookup tables.
  • Will they eventually make it out of the lab and into space? Maybe lightweight transfer learning can help.
  • What are the major technological gaps to be filled in your group’s topic area? Locomotion, harsh environments, friction and environment models are difficult.
  • Which “magic wands” are still being used? Classification of the environment through hard-coding, not using perception.
  • Where does autonomy fit in with humans? It should replace them as much as possible---but the sheer lack of understanding we have of the challenges in space result in a need for in-the-loop problem solving, which only humans can do.
  • 20sec delays are deadly for human teleop, nearly impossible to resolve without high-level planning interfaces and low-level autonomy.
  • “More risk taking would help”---would lead to new applications, rather than being tied to the ground.
  • NASA is engineering-oriented but science-driven; expense realities make it difficult to accept failure.

Space Robotics Competition

SRC and Valkyrie was a great testbed, presents challenges. New designs as parts of that platform were particularly challenging and limited---needs many iterations, e.g. in knee and elbow joints. Was a first step in difficulty.

SRC may evolve to something more, but unclear if actual problems were solved for space robotics.

Most difficulty was a result of the bandwidth restrictive, time-delayed systems, presenting the need to enable high-level teleoperation.

Modular components in design of space robotics very cool. When do we need that versatility? Can it be as reliable as customized platforms?
