바퀴와 다리를 함께 가진 하이브리드 로봇(유틸리티: wheeled + legged)을 소개하는 글입니다. 바퀴형 로봇은 안정적이고 효율적이나 복도·경사·엘리베이터 등에서 제약이 있어 이를 극복하기 위한 바퀴+다리 설계로 공간 제약과 이동성 문제를 해결하려는 시도입니다.

Agile But Safe: Learning Collision-Free High-Speed Legged Locomotion

YouTube

"#Legged #robots navigating cluttered environments must be jointly agile for efficient task execution and safe to avoid collisions with obstacles or humans. Existing studies either develop conservative controllers (< 1.0 m/s) to ensure safety, or focus on agility without considering potentially fatal collisions. This paper introduces Agile But Safe […]"

Agile But Safe: Learning Collision-Free High-Speed Legged Locomotion
#introduction post! My name is Sonia Roberts (she/her) and I'm a postdoc at Northeastern developing #knit sensors for #soft, fully knitted #robots. My PhD work was on #legged robots running around in the desert (ever gone for a beach run?). I use my robots to test ideas about #affordances and #DirectPerception. I have also done some #SciencePolicy and #TechnologyPolicy #policy work around algorithmic transparency and regulating the use of mobile sentries by law enforcement.

Boston Dynamics Atlas Dynamic Duo Tackles Obstacle Course

Historically, the capabilities of real world humanoid robots have trailed far behind their TV and movie counterparts. But roboticists kept pushing state of the art forward, and Boston Dynamics just shared a progress report: their research platform Atlas can now complete a two-robot parkour routine.

Watching the minute-long routine on YouTube (embedded after the break) shows movements more demanding than their dance to the song " Do You Love Me? " And according to Boston Dynamics, this new capability is actually even more impressive than it looks. Unlike earlier demonstrations, this routine used fewer preprogrammed motions that made up earlier dance performances. Atlas now makes more use of its onboard sensors to perceive its environment, and more of its onboard computing power to decide how to best move through the world on a case-by-case basis. It also needed to string individual actions together in a continuous sequence, something it had trouble doing earlier.

Such advances are hard to tell from a robot demonstration video, which are frequently edited and curated to show highlighted success and skip all the (many, many) fails along the way. Certainly Boston Dynamics did so themselves before, but this time it is accompanied by almost six minutes worth of behind-the-scenes footage. (Also after the break.) We see the robot stumbling as it learned, and the humans working to put them back on their feet.

Humanoid robot evolution has not always gone smoothly (sometimes entertainingly so) but Atlas is leaps and bounds over its predecessors like Honda Asimo. Such research finds its way to less humanoid looking robots like the Stretch. And who knows, maybe one day real robots will be like their TV and movie counterparts that have, for so long, been played by humans inside costumes.
