A lightweight robot plays a fast game of catch
What changedRAI Institute researchers built light, backdrivable robot arms for fast physical interaction. AthenaZero throws balls at more than 30 metres per second and catches or bats faster pitches in controlled tests. The hardware makes a lively game of catch possible, though holding heavy loads still brings thermal limits.
The useful part
Why it matters
Reducing moving mass helps a robot react to fast physical interactions rather than only execute slow preplanned motions.
Keep in mind
Good to know
These are baseball-inspired controlled tasks. Sustained static loads can overheat motors, and the demonstrations do not prove general-purpose household ability.
