The development of small size humanoid robot which is easy to use

We designed humanoid robots based on the skeleton. They were easy to make the motions by designing them in the proportion of human. The motions of crawl on the hands and knees, roll-over and crawl on the back were made by using humanoid robot SANDY-3.

ROBO-BLOCK and Rational Formula of Robots

ROBO-BLOCK (robot block system) and the rational formula of robots were proposed. ROBO-BLOCK is composed of servomotors, the parts for servomotor rotor, the brackets for servomotor fixation, the board parts and the controllers. A robot can be assembled easily by ROBO-BLOCK. Meanwhile, it is convenient when the structure of the robot can be described easily as a character. The whole structure of the robot is expressed as rational formula of the robot to show molecule structure in chemistry. ROBO-BLOCK can be useful for not only the research but also the education. SANDY-1 was developed based on the structure formula of human and skeletal structure and the motion was confirmed.

Humanoid by ROBO-BLOCK

Humanoid by ROBO-BLOCK (robot block system) and the rational formula of robots were proposed. ROBO-BLOCK is composed of servo motors, the parts for servomotor rotor, the brackets for servomotor fixation, the board parts and the controllers. A robot can be assembled easily by ROBO-BLOCK. Meanwhile, it is convenient when the structure of the robot can be described easily as a character. The whole structure of the robot is expressed as rational formula of the robot to show molecule structure in chemistry. ROBO-BLOCK can be useful for not only the research but also the education. Creative student experiment was done in the college of industrial technology.

The Application Research of Mobile Robots with Forklift-Driving-Wheels Capable to Ascend and Descend Stairs

To ascend and descend stairs, we have developed the robot assembling fork lifts on the front and the rear. Those fork lifts have driving wheels. The FDW robot(mobile robot with Forklift-Driving-Wheels capable to ascend and descend stairs)is divided into three parts (Body, Front Forklift-Wheels, Rear Forklift-Wheels). The robot can move up and down by the front and rear fork lifts, and also it can be transferred by using these through the stairs and the step. If a condition is satisfied, the robot can get up from the turnover condition by using the fork lifts. The size of a robot being able to go up the stairs of 1-step height 200mm width 300mm becomes about 300×300×300 mm.When a fork lift is set at 2-step-type, the miniature robot of the height 150mm can be made. If the entire length of the robot is more than 300mm, the robot can go up the stairs by assembling the Sub-Rear Fork-lift Wheels. The application such as the wheelchair which can go up the stairs is expected. The position of the chair is lowered in the form that a human being turns a back to the stairs as much as possible to go up the stairs safely. A FDW robot can be applied to a cleaning robot, a guidance robot, a robot for the education and a robot for the baggage conveyance, a wheelchair to go up the stairs, and so on.
