If Disney’s historical past of storytelling has taught us something, it’s to by no means underestimate the ability of an important sidekick. Although sidekicks aren’t the celebs of the present, they supply life and power and transfer the story alongside in essential methods. It’s arduous to think about Aladdin with out the Genie, or Peter Pan with out Tinker Bell.
In robotics, nonetheless, solo acts proliferate. Even when a number of robots are used, they normally act in parallel. One key purpose for that is that the majority robots are designed in ways in which make direct collaboration with different robots tough. Stiff, sturdy robots are extra repeatable and simpler to regulate, however these designs have little or no forgiveness for the imperfections and mismatches which can be inherent in coming into contact with one other robotic.
Having robots work collectively–particularly if they’ve complementary ability units–can open up some thrilling alternatives, particularly within the leisure robotics house. At Walt Disney Imagineering, our analysis and growth groups have been engaged on this concept of collaboration between robots, and we had been in a position to exhibit the results of one such collaboration in Shanghai this week, when slightly furry character interrupted the opening moments for the first-ever Zootopia land.
Our latest robotic character, Duke Weaselton, rolled onstage on the Shanghai Disney Resort for the primary time final December, pushing a purple kiosk and blasting pop music. As seen within the video under, the viewers obtained a kick out of watching him hop up on prime of the kiosk and attempt to negotiate with the Chairman of Disney Experiences, Josh D’Amaro, for a brand new job. And naturally, some new perks. After just a few moments of wheeling and dealing, Duke will get gently escorted offstage by group members Richard Landon and Louis Lambie.
What may not be apparent at first is that the second you simply noticed was enabled not by one robotic, however by two. Duke Weaselton is the star of the present, however his dynamic movement wouldn’t be potential with out the kiosk, which is its personal unbiased, actuated robotic. Whereas these two robots are very totally different, by working collectively as one system, they’re in a position to do issues that neither may do alone.
The character and the kiosk convey two very totally different sorts of movement collectively, and create one thing greater than the sum of their components within the course of. The character is an expressive, bipedal robotic with an exaggerated, animated movement model. It seems to be incredible, but it surely’s not optimized for strong, dependable locomotion. The kiosk, in the meantime, is an easy wheeled system that behaves in a extremely predictable manner. Whereas that’s nice for reliability, it signifies that by itself it’s not more likely to shock you. However after we mix these two robots, we get the very best of each worlds. The character robotic can convey a zany, unrestrained power and pleasure because it bounces up, over, and alongside the kiosk, whereas the kiosk itself ensures that each robots reliably get to wherever they’re going.

The collaboration between the 2 robots is enabled by designing them to be strong and versatile, and with motions that may tolerate a considerable amount of uncertainty whereas nonetheless delivering a compelling present. This can be a direct outcome from classes discovered from an earlier robotic, one which tumbled throughout the stage at SXSW earlier this 12 months. Our fundamental perception is {that a} small, light-weight robotic might be surprisingly powerful, and that this toughness permits new ranges of inventive freedom within the design and execution of a present.
This degree of robustness additionally makes collaboration between robots simpler. As a result of the character robotic is hard and since there’s some flexibility constructed into its motors and joints, small errors in placement and pose don’t create huge issues like they could for a extra standard robotic. The character can lean on the motorized kiosk to create the phantasm that it’s pushing it throughout the stage. The kiosk then makes use of a winch to hoist the character onto a platform, the place electromagnets assist stabilize its toes. Primarily, the kiosk is compensating for the truth that Duke himself can’t climb, and is perhaps slightly wobbly with out having his toes secured. The general result’s a free-ranging bipedal robotic that strikes in a manner that feels pure and fascinating, however that doesn’t require particularly sophisticated controls or extremely exact mechanical design. Right here’s a behind-the-scenes take a look at our growth of those programs:

To program Duke’s motions, our group makes use of an animation pipeline that was initially developed for the SXSW demo, the place a designer can pose the robotic by hand to create new motions. We’ve since developed an interface which might additionally take motions from standard animation software program instruments. Motions can then be adjusted to adapt to the true bodily constraints of the robots, and that data might be despatched again to the animation instrument. As animations are developed, it’s essential to retain a decent synchronization between the kiosk and the character. The system is designed in order that the movement of each robots is all the time coordinated, whereas concurrently supporting the flexibility to flexibly animate particular person robots–or particular person components of the robotic, just like the mouth and eyes.
Over the previous 9 months, we explored just a few totally different sorts of collaborative locomotion approaches. The GIFs under present some early makes an attempt at driving a tricycle, skateboarding, and pushing a crate. In every case, the thought is for a robotic character to finally collaborate with one other robotic system that helps convey that character’s motions to life in a secure and repeatable manner.

This demo with Duke Weaselton and his kiosk is only the start, says Principal R&D Imagineer Tony Dohi, who leads the challenge for us. “In the end, what we confirmed immediately is a crucial step in direction of an even bigger imaginative and prescient. This challenge is laying the groundwork for robots that may work together with one another in shocking and emotionally satisfying methods. At the moment it’s a personality and a kiosk, however transferring ahead we need to have a number of characters that may have interaction with one another and with our company.”
Walt Disney Imagineering R&D is exploring a multi-pronged growth technique for our robotic characters. Partaking character demonstrations like Duke Weasleton concentrate on rapidly prototyping full experiences utilizing instantly accessible strategies. In parallel, our analysis group is growing new applied sciences and capabilities that grow to be the constructing blocks for each elevating current experiences, and designing and delivering fully new reveals. The robotics group led by Moritz Bächer shared one such constructing block–embodied in a extremely expressive and stylized robotic strolling character–at IROS in October. The capabilities demonstrated there can finally be used to assist robots like Duke Weaselton carry out extra flexibly, extra reliably, and extra spectacularly.
“Genuine character demonstrations are helpful as a result of they assist inform what instruments are essentially the most useful for us to develop,” explains Bächer. “Ultimately our purpose is to create instruments that allow our groups to supply and ship these reveals quickly and effectively.” This ties again to the basic technical concept behind the Duke Weaselton present second–collaboration is vital!
