A bit like those found in cheap table tennis sets we used at home in the dining room. At the World Championships in Prague, the first point in a match between players from Poland and Romania lasted two hours. Subsequent changes in blade and bat surface technology have transformed the sport into the high-speed spectacle it is today. These days, top players hit the ball at up to 70mph and can impart 3, revs per minute spin.
To do well at major tournaments they must combine giant robot spider youtube icon and fast reflexes with the chess-like acumen of their predecessors. Mayer set up an ordinary table-tennis table, installed two PlayStation CL-eye cameras to track the ball in real time, and a full-HD Projector to send information captured to the table in the form of data visualisations. With these, players can track the direction of their shots.
The technology also stores player stats, to help them measure giant robot spider youtube icon. Bryant is concerned, though, that too much reliance on data could leave participants with information overload.
InFrench researchers designed a motion-sensing system that provides real-time feedback by installing accelerometers and a gyroscope in the bat handle. Swedish manufacturer Stiga has put sensors into a table-tennis table to enable tracking of the ball bounce and keep score automatically.
Chinese researchers are devising their own intelligent scoring system, which also includes vibration sensors in the net and an LED panel to display the moving ball and calculate scores. Then, of course, there are training robots, which are mechanical devices that send out balls for players to practice shots and giant robot spider youtube icon reflexes.
Most can deliver balls with topspin, backspin and sidespin. The more expensive models can also tilt up and down to deliver lobs and serves, or float the ball up. Trainerbot, for instance, can be programmed via smartphone to send the ball to any area on the table, or a combination of areas.
The app enables players to design their own games and drills. Bryant believes players still need to practise against other people. Reacting to these variations is part of the game. There is one robot that does hold its own bat. The Omron Forpheus robot Future Omron Robotics Technology for Exploring Possibility of Harmonised Automation with Sinc Theoretics looms over the table-tennis table like a giant spider and uses robotic arms to manipulate the bat. Earlier this year, Forpheus made it into the Guinness World Records as the first ever robot table-tennis coach.
The robot then uses that information to provide an appropriate return. Howell believes robots, smart tables and other such technology might be useful giant robot spider youtube icon encourage giant robot spider youtube icon beginners to take up the sport, but insists that playing against other humans is what makes elite table-tennis players better.
The firm just used this particular sport as a way of demonstrating human-robot interaction. Not that Forpheus would ever catch on as a playing partner for recreational players, unless someone designed one short enough to fit under the living room ceiling. Even if someone did produce such a robot and anyone other than George Clooney, a big fan apparently, could afford it, who would actually want a giant metal spider looming across their living room?
Swedish bat-maker Stiga giant robot spider youtube icon just released its seventh and last bat for the year, Arctic Wood. Stiga has six different technical specs for its bats, seven specs for blades, ten different rubbers Elite players have them designed to meet their own specific style of play.
Table-tennis bats have come a long way from those old rigid wooden things covered in thin, pimpled rubber. Modern bats have a spongy sub-layer under a high-friction surface, which increases the sideward force between the paddle and the ball. The spongy sub-layer provides increased contact time and contact area. Manufacturers alter speed, spin and density of giant robot spider youtube icon rubber to fit individual styles. Butterfly, for instance, has 44 rubber specs.
Some have pimples facing inward, providing a larger contact area and enabling the player to impart more spin. Others have pimples facing out, which means the player is less affected by spin from their opponent — it has a smaller contact giant robot spider youtube icon and the ball stays on the bat for less time.
The blade provides the bat with a solid foundation. Some blades are made from wood, others from composite carbon and wood. In general, carbon blades work well for fast, attacking play. Slower, defensive players or beginners might prefer a wooden blade. Bryant adds that an elite player needs to know their method and giant robot spider youtube icon sort of bat complements it.
