The Murata Cheerleaders, robotic cheerleaders that dance in sync


Murata Cheerleaders

(EFE) - Tokyo (EFE) - Murata, a Japanese technology company, unveiled its next generation of robots today in Tokyo, consisting of ten little and happy cheerleaders who can hold onto a ball and do synchronized choreography without clashing.

Each robot is equipped with three gyro sensors that detect their leaning direction and cause them to move in that direction.

During the wheel presentation today, project leader Koichi Yoshikawa remarked, "We want the Murata Cheerleaders to inspire young researchers in their new discoveries and put smiles on people's faces around the world."

The robots, which will not be sold, incorporate technologies that could be useful in the real world and highlight Japan's inexorable robotics growth.

Their 36 centimeters in height and 1.5 kilos in weight are sufficient to give them an hour of autonomy and conceal the secrets that allow these cheerleaders to swing at 30 centimeters per second without hitting or falling.

To accomplish this, each robot is equipped with three gyro sensors that detect the direction in which they are leaning and cause them to move in that direction. This is an update of the system developed for the previous Murata Boy and Murata Girl models, to which a technology that allows them to detect angles of rotation has been added.

According to Yoshikawa, these sensors are identical to those found in cameras, automotive navigation systems, and the most recent electric stability control (ESC) systems in vehicles, which keep them from skidding.

In addition, each robot has five ultrasonic microphones and four infrared sensors hidden in its helmet that identify its present position and allow it to locate anything within a 16-meter radius, even in the dark.

The data obtained by these sensors is transmitted among them over a wireless network, allowing each cheerleader to properly find the others while dancing with their multicolored LED pom-poms and avoid any possible collisions.

This group control technique was created in partnership with experts at Kyoto University's Matsuno Laboratory and can be used to develop "safer and more efficient" vehicles and transportation in the future, according to Yoshikawa.

Other potential applications for this sensing and communication technology include energy management systems for homes and buildings, as well as the transmission of people's vital signs and "advanced" healthcare, he added.

The Murata Cheerleaders, whose public debut coincides with the company's 70th anniversary, are the fourth generation of Murata robots, following the introduction of the first Murata Boy in 1991, the second in 2005, and the arrival of Murata Girl in 2008.

The new Murata cheerleaders will be on exhibit at the forthcoming Ceatec 2014 in Tokyo, where they will be on display between October 7 and 11.
