Create Future Science (CREFUS) is an extra-curricular science program located in Japan. It created a robo mascot to represent this program, the FILIO robot.
Vstone was also commissioned to develop and create a working version of this robot back in 2006. The purpose of this was to utilize the robot as a way to demonstrate more advanced robot technology to the students.
As time went on, several other developers began making this kind of robot, making FILIO relatively obsolete. The Filio is about the height of the Black Ox Robot and has a design almost similar to Team OSAKA’s Vision Robot.
