IVAN SUTHERLAND'S TROJAN COCKROACH
Ivan Sutherland and his machina versatilis, then and now
Ivan Sutherland’s Trojan Cockroach tells the story of computer graphics, walking machines, and the origins of the technology underlying modern advances in robots. The protagonist of the exhibit, Ivan Sutherland, is often considered the father of computer graphics. An alum of Carnegie Tech in the 1950’s, Sutherland went on to develop one of the first human computer interfaces for graphics at MIT.
I curated an exhibit in a rare books archive, the Posner Center, framed around these old robotic parts as well as a number of rare books from the 16th and 17th century detailing the foundations of technological innovations that led to robotics.
I found the parts of an important robot he built in the 1980's, the Trojan Cockroach in the hallway of the basement of Wean at Carnegie Mellon in Pittsburgh. Images above show the parts on display.
1. HISTORY OF COMPUTER GRAPHICS AND VIRTUAL REALITY
Ivan's breakthrough MIT Thesis Sketchpad is in the first case, with two images, one I found in the archives of a young Ivan, another he independently sent me of himself with one of his early robots. Also the godfather of virtual reality, this case focuses on Ivan's graphics work.
2. THE TROJAN COCKROACH
This case focused on the Trojan Cockroach.
It features hydraulic cylinders from the original machine, a first printing of A Walking Robot by Ivan E. Sutherland, an issue of Scientific American depicting the robot, the first Robotics PhD from Marc Donner, several springs, and other odds and ends from the machine. Images of the Trojan Cockroach in action, schematics, and a 3D printed miniature of the foot. The black back and base are both Boston Dynamics terrain simulations for walking machine training experiments.
3. HISTORY OF WALKING
This case has an early edition of Muybridge's Animal Locomotion: an Electro-Photographic Investigation of Connective Phases of Animal Movements, first printing of Karel Capek's R.U.R. Rossum's Universal Robots, an original Passive Walker mechanism designed by Tad McGreer, a first printing of Galvani's DeVibribus Electricitatus, 1791, Isaac Asimov's I, Robot first edition, multiple machine parts, mounted on a Boston Dynamics terrain simulator.
4. HISTORY OF WALKING MACHINES
A History of Walking Machines, a short historical survey, with multiple rare images of unique robotic experiments in legged locomotion and significant texts about legged locomotion.
5. THE LEG LABORATORY
The story of this robot is part of a larger conversation about how to replicate biological skill and agility in machines. What should the brain do? What should the body do? The philosophy at CMU was that "intelligence" should be built into the body, to provide fast stable reflexes and simplify what the brain has to do. Sutherland used hydraulics to coordinate legs. Marc Raibert put physical springs to generate hopping behavior into robots at his "Leg Laboratory", which then led to the quadrupeds Big Dog and Spot at Boston Dynamics.
6. LITTLE DOG AND LEIBNIZ
The final case housed a "Little Dog" the micro-version of Boston Dynamic's Big Dog, next to Leibniz's Arata Eructordorium, an early scientific journal that depicts the first conceptual sketch of the modern calculator.
In conjunction with the exhibition I hosted several events in partnership with the University archives and the Robotics Institute. One event featured a joint lecture with Ivan Sutherland and Marc Raibert, another featured a reunion of many Leg Laboratory members and young students working on legged locomotion. Four total events engaged the public in the show in a variety of ways, and attempted to bring together audiences from the arts and robotics in an intergenerational context.
