How Disney’s Stunt Robot Flies Like Spider-Man

Disney California Adventure, located in Anaheim, California, USA, has the Avengers Campus, a theme park for the Marvel Cinematic Universe. Among them, one of the attractions is the Spider-Man Show, where Spider-Man actually jumps from a height of close to 20 meters without a lifeline. Of course, in reality, this aerial jump uses a stunt robot developed by Disney, not a human. The Disney robot development team draws attention by explaining how the stunt robot was developed and the hardships it suffered.

This stunt robot was originally developed by a project called Stuntronics. The prototype of the stunt robot was a robot called Brick. Because the brick can control its center of gravity, it can control its posture and rotate autonomously in the air.

Stickman is the one that made this brick damper joint to fold into the air together. The stickman grabs the rope and moves the joints to gain momentum, and can release the rope and jump at the right time while measuring the angle and position with the swing sensor.

The humanoid prototype was created after further development of this stickman and a half-scale prototype. With this doll prototype stunt robot, the development team begins moving tests that actually operate at the attraction. It is said that he suddenly tried to fly from a height of 12m from the beginning.

The stunt robot has built-in accelerometers and angle meters like those built into smartphones, so that it can move as planned. For outdoor use, the development team was also measuring the climate around Disney’s California Adventure and taking into account wind effects. As a result, the stunt robot is said to be able to land on a location almost as intended. In addition, the test jump altitude gradually increased so that the stunt robot could jump up to 20 meters.

What bothered the development team here was how to make the stunt robot look like Spider-Man. Even if it flies perfectly, if it passes perfectly, on the contrary, it loses its humanity, let alone Spider-Man. For example, Spider-Man flies through the city while operating a smartphone in the movie. And even in a situation where it is likely to hit the bus, he hastily solves it on the spot, maintaining his posture and continuing to jump. In other words, it’s more like Spider-Man if you break your stance a little in the air.

When the stunt robot releases its hand from the swing rope, it crouches and jumps and spins around. And because the center of gravity collapses during the jump, the stunt robot adds a side rotation like twisting the body. If you add distortion to a humanoid robot that is not a simple form such as a brick, it is quite complicated to calculate, but the movement in the air with one hand is irregular, so it looks like Spider-Man, not a robot, is actually jumping.

Also, stunt robots always have a problem of chak-di. When landing, use a 4m four-sided mat to slow down the moment you land. But the stunt robot flies 24/7 several times a day. Therefore, it is quite difficult to make it strong enough to withstand the impact. Therefore, the stunt robot is made of resin parts printed with a 3D printer and an aluminum frame so that it can be easily separated. In addition, it is said that even if the landing fails, only the 3D printer parts are damaged instead of the expensive-sensitive control device. The development team hopes to apply the robot technology to not only Spider-Man, but other characters as well.

Through the monthly AHC PC and HowPC magazine era, he has watched 'technology age' in online IT media such as ZDNet, electronic newspaper Internet manager, editor of Consumer Journal Ivers, TechHolic publisher, and editor of Venture Square. I am curious about this market that is still full of vitality.
