The baseball batting robots are two robot arms, where one is the pitcher and the other is the batter. The pitcher can target the strike zone at 40kph (25mph) 90% of the time, while the batter can hit the ball 90% of the time only 3.5 meters (11ft) away. In order to do this, the robots require cameras that capture the position of the ball at one thousand frames per second. What appears very fast to human eyes can be tracked slowly by the camera, which then informs the robot arms’ control software exactly where the ball is. In the future, the researchers expect the pitcher to throw the ball at 150kph (90mph), while the batter should be able to hit the ball in specific directions.
The baseball batting robot has been making the rounds through various news outlets since last week, and while the demonstration was cool, the object tracking computer vision software that allows the robot arms to perform the feat remains an unsung hero. Doing a little digging into the Ishikawa Komuro Laboratory (part of Tokyo University) website unearthed some cool videos that show off just how accurate their computer vision software really is.
For example the robot arms can not only pitch and bat balls, but can catch them at high speeds, dribble them so fast you can barely keep an eye on the ball, position themselves properly to shake a roving human hand, and tie knots with one hand. And while they haven’t perfected directional hitting, the robot can bat the ball into high or low nets repeatedly, even when the ball is thrown by a human pitcher. A different type of computer vision software tracks an object’s position in 3d space (videos after the break).

Yujin Robot’s drink serving robot “Cafero”, is taking and delivering orders from customers at the Robot Cafe located in Songdo U-city, South Korea. The city is part of Incheon Free Economic Zone, an area designed to provide information on the city’s cutting-edge ubiquitous industry and opportunities for citizens to experience it firsthand.

Mitsubishi’s Wakamaru turned out to help celebrate the Osaka Tenjin Festival on July 25th 2009, a tradition which dates back at least 1000 years. One of the three largest festivals in Japan, it attracts more than a million visitors annually. One of the processions is called Funatogyo, a procession of about 100 boats transporting Shinto deities along the Dojimagawa River. Osaka University has participated in the festival for the last five years, but this is the first year to include a robot on the Handai boat.
Wakamaru appeared before an audience of 200 people, dressed in the attire of the Heian period (794-1185) omukae ningyo (welcome dolls) placed onboard to greet the floating Shinto shrines as they pass by. Incidentally this is the same style of dress that would have suited Minamoto Yoshitsune (“Ushiwakamaru”, Wakamaru’s namesake). The tradition of placing welcome dolls on the prow of boats carrying shrine parishioners gradually died out after World War II.
Wakamaru’s performance breathes new life into the tradition for the 21st century. Engineers at Osaka University added the motions of the Osaka-jime, the festival’s customary rallying call and clap, to the robot’s repertoire of morning exercise routines prior to the event. Associate Professor Koizumi commented that,”Typically outdoor performances are tricky, but everything turned out ok.”

This insane animation reminiscent of Heavy Metal and Yellow Submarine is called “BIRDY NAM NAM – THE PARACHUTE ENDING”. I don’t know what’s going on, but I do know I like it, and this Steve Scott fellow is insanely talented.
