Is the arm actually compensating for changes in the ball's flight, or just performing a programmed repetitive movement?

[GerbilGod7]

The arm and hand are adapting for every catch and throw based on data from two high-speed cameras that track the balls.

That is fantastic engineering.

[maddride]

amazing

[Martin Gardner]

It's very "human".

cool video...check out my video...OMIT RAPPING

[lmaka1]

Variables like friction, aerodynamics, the position of the ball in the hand (the robot will not catch the ball in an identical position every time) will affect the trajectory of the ball.

[Marcus Aurelius]

he failed at last one!!!

[tangocharliee]

i have some question .. when if grasping, throwing(speed) and catching technique is the same so why the throw height and direction may differs after 3 cycle ... is there aerodynamic issues or three finger cant grasp the ball accurately..or it needs palm

[Narek Alaverdyan]

no problems))) just read my opinion again

[Emil Dahl]

Beat the human in numbers!

- a juggler

[Narek Alaverdyan]

cant understand people who hit dislike on such great technology video

[Robert Liberatore]

Whatever, it's juggling towards itself. Newb,
