Nikkei Robotics News Crew started to tear down the "Pepper" home-use humanoid robot, which is sold by SoftBank Robotics Corp.
We started the teardown by opening the head of the robot. After removing two claws located near the neck, the head was pulled out from the body. The head was connected to the body with a limited number of contacts.
There were few screws on the casing of the Pepper. It seemed that most of the parts were fixed with claws inside the robot. The panel-like part covering the top of the head was no exception.
We inserted a blue pin that came with the robot into the gap between the panel-like cover and the rest of the head. The pin is normally stored on the waist of the robot and used for releasing the braking applied to a motor.
We inserted the pin and pulled out the panel-like cover with an unexpected ease.
Then, a microphone array, touch sensor, etc appeared.
However, we could not find screws fixing another panel-like cover located in the lower side of the head. After examining the surface of the head, we found rice grain-sized parts that have a slightly different color. We thought they were covering screws. However, there was no gap at all, and we could not insert an object and remove the parts.
Therefore, we resorted to an extreme measure: drilling.
We passed the point of no return.
Luckily, there were screws. We removed the four screws located deep inside the hole one by one.
We cheered with delight.
The casing was split into two, and a printed circuit board (PCB) appeared.
