This impressive RC-sized VertiGo has a special trick:

"VertiGo is a wall-climbing robot that is capable of transitioning from the ground to the wall, created in collaboration between Disney Research Zurich and ETH. The robot has two tiltable propellers that provide thrust onto the wall, and four wheels. One pair of wheels is steerable, and each propeller has two degrees of freedom for adjusting the direction of thrust. By transitioning from the ground to a wall and back again, VertiGo extends the ability of robots to travel through urban and indoor environments."

"The robot is able to move on a wall quickly and with agility. The use of propellers to provide thrust onto the wall ensures that the robot is able to traverse over indentations such as masonry. The choice of two propellers rather than one enables a floor-to-wall transition - thrust is applied both towards the wall using the rear propeller, and in an upward direction using the front propeller, resulting in a flip onto the wall."

The VertiGo isn't new—it was created over ten years ago, in 2015. Ultimately the whine of the propellors ruled it out as a saleable or amusement-park-supporting product. However, the technology within it—specifically the Inertial Measurement Unit (IMU) that allowed the 'bot to estimate its orientation in space—lived on. Development continued on the IMU and today it's inside the Spider-Man Stuntronic robot, which is one of the headline spectacles at Disney's California Adventure Park.

During the show, a human performer dressed as Spider-Man disappears into a structure, and then the robotic Spider-Man emerges, launching into an acrobatic leap. The IMU is part of what allows the robot to appear so lifelike during the jump:
