Iketomu, a Japanese blogger and robot enthusiast who maintains an English blog, has uploaded some videos from the 7th Wonderful Robot Carnival which took place on July 19th, 2009. For the uninitiated, it’s a Robo-One style tournament with several events that push the limit of the competitor’s custom-built hobby robots:
- Dash 2000 (2 meter foot race)
- Bottle Traction (moving a basket of bottles to the finish line)
- Dice Shot (1-on-1 soccer with fuzzy dice)
- Cubes (teams score points by moving cubes to their goal)
- Rumble Fight (multiple robot battle)
- 1-on-1 Fight

Matec Yao (Management & Technology Interchange Group Yao) is an organization formed in 2004 that gives introductory courses on electronics and robotics to everyday citizens with the goal of expanding interest in robotics and engineering in Yao, Osaka. They hold their own Robo-Con events where robot lovers get the chance to meet with other enthusiasts. In May 2009, they developed an eco-friendly robot to teach children about recycling called the Recycling & Environment Robot with the help of NAIST students.
Children can quiz the robot to determine what recycling bin a can or bottle should go in. You give the robot a recyclable, and after thinking for about 15 seconds it gives you the answer. It comes to a decision by squeezing objects placed in its hand, determining if the object is metal or plastic from the level of deformation registered by its strain gauges. It’s not always 100% right, since some plastic bottles have ribbing which makes them difficult to differentiate from aluminum cans, but the system tracks erroneous decisions to help improve the robot’s accuracy.
The late Dr. Aizawa Zirou (1903-1996), the first director of the Children’s Institute for Cultural Activities Foundation, built around 9 large humanoid robots between 1950-55 which became famous through local events, television appearances, magazines, and at Osaka’s Japan World Expo in 1970. Since then they’ve been asleep inside an old warehouse in Yubari, Hokkaido, and only recently rediscovered.
The Kanagawa Institute of Technology’s (KAIT) Department of Mechatronics is busy restoring the robots to working condition, and will be showcasing them in all their glory at Japan Robot Festival 2009 in Toyama. Following that, they will be displayed in art galleries and museums around the country as budget allows. The restoration project is attempting to use original parts where possible, though procuring working vacuum tubes and the like isn’t easy.
Amazingly, Dr. Aizawa was friends with the founder of SONY, Masaru Ibuka, and the creator of Astro Boy, Osamu Tezuka, with whom he established the Children’s Institute for Cultural Activities Foundation in 1927. Their ideal of improving the welfare of children through scientific toys led Dr. Aizawa to create 800 humanoid robot toys. He even trademarked the term “robot” in 1934 in Japan, though the term was actually invented by Karl Capek for his 1920 play Rossum’s Universal Robots, and later grew in prominence thanks to sci-fi magazines like Amazing Stories (1926) and Fritz Lang’s classic film Metropolis (1927).

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).
