Safety measures in "wakamaru"

Efforts to ensure the safe use of "wakamaru"

Because "wakamaru" is a robot designed to blend into daily life, safety is our first priority. We can ensure that no human being will be harmed throughout the life cycle of our product. Using an international risk assessment method, we have analyzed all possible risks , associated with the use of "wakamaru" and minimized these of such risks by all possible means using the latest technology.

Essential safety design

Under the guidance of an ophthalmologist , the fingers are made of soft and smooth material, with no burr so that the eye may not be hurt in case wakamaru's finger might strike the human eye, by using a special manufacturing technology.

The movement of wakamaru's arms and wheels has been confirmed not to cause any serious injury in the case of collision due to any malfunction through experiments with dummy dolls used in automobile collision tests.

Natural movement

Even for a "collision- safe" robot, it would be a matter of concern if the robot were to collide with people and objects.
"wakamaru" can see and avoid walls and obstacles in its course using ultrasonic and infrared sensors. It may be configured to stop at the occurrence of any contact with the bumpers on its shoulders and hands. During operation, the force of movement of the arms and head are carefully monitored. If these come into contact with a person or object, such movement will be controlled relative to the person or object. Furthermore, if anything gets pinched in the sides, there is a release switch to stop the movement of the arms.There is also a satchel or a bag switch on its back to stop any movement if it opens up.
