Continued from 'Pepper' Humanoid Robot Teardown (2)
We began to remove the back of the Pepper humanoid robot. We knew that it could be easily detached when we examined the robot beforehand.
After detaching another panel, three fans were exposed. They seemed to cool the motors that move the neck and the right and left arms of the robot, respectively. The central fan is the largest probably because a heavy load is applied to the motor that moves the neck.
Below the fans, there was a printed circuit board (PCB) that seemed to be used for power distribution. The red button (top in the picture below) is for emergency shutdown.
The mechanical component equipped with the fans was fixed with four screws (top in the picture below). When the screws were removed, it flipped open, exposing actuators that move various parts.
However, we had not idea how to remove the exterior panel that covered the front side of the robot though it seemed to be fixed with claws.
We looked for hints by using a lamp, pressing suspicious areas, using a screwdriver to pry it open, etc.
Finally, we disengaged the claws. The claws were engaged in a complicated way, making it difficult to detach the panel without getting used to it.
After pulling out a USB cable connected to the tablet on the chest, we removed the exterior panel.
Probably for improving strength, the inside of the robot has a complicated structure that consists of many planes crossing lengthwise and breadthwise.
We moved on to remove the two arms, which turned out to be heavier than we expected, thinning and emptying the upper body.
We removed the neck and the exterior of the lower body.
It no longer looked like a humanoid robot.
