(a) Press release: The first Robot That Mimics the Water Striders’ Jumping Abilities. ACS News Service Weekly PressPac, July 25, 2012 http://portal.acs.org/portal/acs ... b-a80d-eb3b58e2ba68
("Using porous, super water-repellant nickel foam to fabricate the three supporting and two jumping legs, the group made a robot that could leap more than 5.5 inches, despite weighing as much as 1,100 water striders. In experiments, the robot could jump nearly 14 inches forward – more than twice its own length – leaving the water at about 3.6 miles per hour.")
(b) The same team last year made a similar robot that could WALK (but could not jump) on water.

("It’s six inches long and weighs about as much as a wooden pencil, or 1,000 times the weight of a real water strider")
I can not find a similar video clip in YouTube.com.

(b) The article said, "Disembodied arms at the University of Tokyo pitch baseballs, and bat them back, with uncanny accuracy. Engineers in Munich have built a pool-playing automaton that can pot five balls in a row. Their counterparts at Zhejiang University in China boast a pair of humanoid table-tennis players. (They can rally with a human for 145 strokes, and with each other for about 180.)"
