Robot-shaped climbing stairs

The robot is named Nao and has a human form, it can escalate quite accurately, but the climb speed is still very slow.

Scientists at the University of Freiburg in Germany have successfully demonstrated a robotic escalator, especially the spiral staircase, which is popular in today's buildings.

The robot named Nao, in order to climb the spiral staircase, on Nao's head is equipped with a laser scanner to determine the current position of the robot at each ladder, then Nao will redraw it as 3D model, combined with the laser light above so that it can escalate accurately. When it reaches the twist of the stairs, it will carefully rotate to align with the ladder at that position and then move on.

Nao's disadvantage is that its climbing speed is too slow. At each climbing step, it must shoot at least 3 images of the next step to the next step (shooting the left corner, right corner and current position). of the robot).

With this robot, in the future, perhaps the prospect of lying in bed every morning on the second floor and waiting for the robot to bring food up not far away.
