As a lot as we’d like to assume that we’re getting into an period of autonomous robots, they’re really nonetheless fairly helpless. To keep them from falling down on a regular basis, a human’s quick reflexes may very well be the answer. But the human has to really feel what the robot is feeling — and that’s simply what these researchers are testing.

Bipedal robots are wonderful in concept for navigating human environments, however naturally are extra inclined to falling than quadrupedal or wheeled robots. Although they typically have subtle algorithms that assist keep them upright, in some conditions these simply won’t be sufficient.

As a approach to bridge that hole, researchers at MIT and the University of Illinois-Champaign put collectively a kind of hybrid human-robot system harking back to both Pacific Rim or Evangelion, relying on your nerd alignment (or Robot Jox, if you need to go that approach).

Although the references could also be sci-fi, the necessity for this type of factor is actual, defined U of I’s João Ramos, co-creator of the system with MIT’s Sangbae Kim.

“We were motivated by watching the 2011 Tohoku, Japan, earthquake, tsunami and subsequent Fukushima Dai-ichi nuclear plant disaster unfold. We thought that if a robot could have entered the power plant after the disaster, things could have ended differently,” Ramos stated in a U of I information launch.

The robot they created is a small bipedal one they name Little Hermes, and it is attached immediately to a human operator, who stands on a pressure-sensing plate and wears a force-feedback vest.


The robot usually follows the operator’s actions, not in a 1:1 sense (particularly because the robot is way smaller than an individual), however after decoding these actions by way of heart of gravity and pressure vectors, makes a corresponding one virtually concurrently. (The MIT writeup goes right into a bit extra element, as does the video beneath.)

Meanwhile, if the robot have been to, say, encounter an sudden slope or impediment, these forces are conveyed to the operator by way of the vest. Feeling strain indicating a leftward lean, the operator will reflexively take a step in that course utilizing these wonderful instincts we animals have developed. Naturally the robot does the identical factor and, hopefully, catches itself.

This suggestions loop may make on-site rescue robots and others on unsure footing extra dependable. The know-how shouldn’t be restricted to legs, although, and even to Little Hermes. The group needs to arrange related suggestions techniques for ft and arms, so mobility and grip will be additional improved.

The group printed their work as we speak within the journal Science Robotics.
