Autonomous Movement

Human and labor-free Autonomous Movement

"wakamaru" is not a home electric appliance that you just turn on when you want to use it. Nor is it a conventional robot that activates after receiving a command.
Rather, it remains active without any assistance from humans as long as it is powered on.
"wakamaru" has its own daily life cycle and moves around autonomously. It wants to draw near to people in movement, stays active throughout the day by recharging itself when necessary, and takes a rest at the charging station at night.
"wakamaru" has two types of daily life cycle, its own and a pre-determined one set at the owner's site.

Customizeation of activityity time and types

"wakamaru" may operate continuously as long as it is powered on. The owner canmay set the a time at which "wakamaru" will become starts its activitye in the morning, or stop at night. "wakamaru's" daily activities canmay be set according to by day of the day of the week.

  • Stay at charging station.
  • Stay near office reception.
  • Move around designated area.
  • Sleep at charging station.

"wakamaru" will recharge or move as necessary when in modes 1 and 3.
When in mode 4 it will be inactive unless instructed. During the night, he will remain at the charging station in mode 4.

Autonomous movement technology

"wakamaru" moves around using the charging station as his base spot.
It memorizes routes and specific locations(such as entrances, furniture, etc.) previously learned, and moves around along predetermined routes while identifying its own position. "wakamaru" has LED lights on the sides of a camera on top of its head, giving off light reflected by markers unseen by the human eye. The camera detects such reflected light to confirm "wakamaru's" location using the triangulation principle of measurement.

Obstacle avoidance technology

Obstacle avoidance technology

"wakamaru" is equipped with several sensors to avoid obstacles.
These sensors are used to avoid walls and other obstacles, as well as to stop at steps.

  • Long-distance ultrasonic sensor.
  • Short-distance infrared wide-angle sensor.
  • Infrared sensor to detect steps.
  • Side infrared sensors to detect sides.
  • Bumper sensor to detect collisions.
