Robots shoot for the moon in MIT’s annual 2.007 competition

Of their historical lunar project 50 years in the past, Apollo 11 astronauts Buzz Aldrin and Neil Armstrong gathered and returned to Earth greater than 48 kilos of lunar subject matter, together with 50 moon rocks that researchers had been inspecting intensely ever since. In the event that they’d simplest had assist from some MIT robots, the astronauts may had been in a position to convey again much more lunar loot.

On Thursday night, scholars of MIT’s widespread elegance 2.007 (Design and Production I) proved that robots can also be environment friendly, creative, or even extremely entertaining moon-rock scavengers.

Over 4 regularly nail-biting hours, 32 pupil finalists, winnowed from a roster of 165, competed head to machined head, within the route’s annual robotic festival, held within the ice rink at MIT’s Johnson Athletic Middle. This 12 months’s theme, Moonshot, used to be an homage to the Apollo 11 moon touchdown, celebrating its 50th anniversary this 12 months.

The route designers and machinists took the theme to center, establishing two large, similar recreation forums over which pairs of student-designed robots confronted off. On the heart of every board stood a duplicate of the Apollo 11 lunar module, or LEM, which served as the contest’s place to begin. Ramps on all sides of the LEM sloped right down to a lunar-like floor, affected by “moon rocks” — stones of more than a few shapes and sizes, which, for sensible functions, have been of Earthly foundation.

The problem known as for college kids to move their robots, which both moved autonomously or have been remotely managed, from the LEM’s place to begin right down to the “lunar” floor to gather as many moon rocks as conceivable, and go back them as much as the LEM, inside two mins. Robots received extra issues by way of planting a small flag on a hillside, spinning a wheel to “rate” the LEM’s battery, and pulling a wire to jettison two weights — a in particular difficult process that, if achieved, would cause the LEM to “carry off,” to dramatic smoke and sound results.

“The contest identify could be very apropos of the problem that the scholars face, as a result of for plenty of of them, creating a robotic by way of themselves for the primary time is a moonshot,” says Amos Iciness, route co-instructor and affiliate professor of mechanical engineering at MIT. Iciness and Affiliate Professor Sangbae Kim served as the contest’s emcees, each suited up for the instance in astronaut tools.

The two.007 festival is a once a year custom that dates again to the 1970s, with the route’s first teacher, Woodie Plant life, the Pappalardo Professor Emeritus of Mechanical Engineering, who evolved 2.007 as some of the first hands-on, project-based undergraduate lessons.

Each and every 12 months, at first of the semester, scholars are given the similar toolbox of portions, together with gears, wheels, circuit forums, and microcontrollers. Via lectures and time — a lot of time — within the lab, scholars discover ways to design and system their very own robotic, to hold out that 12 months’s festival demanding situations.

This 12 months’s problem impressed a spread of robot methods and designs, together with a bot, aptly named Scissorlift, that stretched itself up by the use of a scissoring mechanism to plant a flag, and a two-bot device named Lifties, comprising one robotic that hoisted rocks as much as a 2d robotic by the use of a telescoping arm.

Whilst maximum scholars was hoping for a win, sophomore Jaeyoung Jung merely sought after to entertain. After soliciting for that the development’s overhead song be grew to become down, Jung, carrying a tuxedo, made some song of his personal, taking part in a recorder that he had rigged to move his robotic. Each and every notice he performed used to be transformed to electric indicators that have been picked up by way of a pc, which in flip despatched a corresponding command to the robotic’s controller to spin a wheel and rate up the LEM.

Even though the contest’s first music-controlled robotic didn’t make it throughout the first spherical, it used to be met with cheers from an regularly raucous crowd of friends and family, who have been handled sporadically with a confetti of custom-designed foam astronauts fired from an air cannon.

Some of the enthusiastic crowd used to be Evelyn Wang, head of the Division of Mechanical Engineering, and her two small children, who have been seeing the engineering spectacle for the primary time. The contest introduced again reminiscences for Wang, who participated in 2.007 when she herself used to be an MIT undergraduate. That 12 months, she recollects having to compete on a recreation board dubbed “Ballcano,” for a volcano-like construction that spit out balls, which robots needed to catch and distribute at more than a few places around the recreation board.

“It used to be the primary time I discovered design, construct, system, and paintings with other actuation mechanisms and motors and pneumatics,” says Wang, who proudly recollects taking house fourth position.

Because the night time wore on, robots battled over who may just scrabble up essentially the most moon rocks, the use of numerous designs, from grippers and grabbers to snowplow- and comb-like sweepers, and rotating flippers and flaps. Between every bout, route assistants briefly repositioned the moon rocks and swept the sport board of any residual moon rock mud that might make a robotic slip. To cope with this possible danger, some scholars designed their bots with further traction, lining their wheels with Velcro or, on the subject of one bot named Sloth, rubber bands.

Sophomore Jessica Xu, whose spiky, rock-snatching “Cactus-bot” made it the entire technique to the semifinals, says that 2.007’s hands-on revel in has helped to persuade her towards a mechanically-oriented occupation.

“That is my first revel in ever even considering of creating a robotic,” Xu says. “I began the category googling, ‘What are mechanisms that robots even do?’ As a result of I wasn’t even certain what the chances have been. I got here into school in need of to do one thing that applies to well being care. Now I’m hoping to pay attention in scientific gadgets, making use of the mechanical facet. I’m excited to peer what it might be.”

Finally, it used to be an impressive, motor-heavy bot named Rocky that devoured up rocks “like Cookie Monster,” as Iciness reported to the gang, that took house the prize. Rocky’s dressmaker, sophomore Sam Ubellacker, says it will had been the bot’s pressure educate that made the adaptation. Whilst maximum scholars integrated two motors of their pressure trains, Ubellacker opted for 4, with a view to transfer two times as speedy as his competition — an 11th-hour choice that in the long run paid off.

“I just about redesigned my complete robotic the week prior to this festival, as a result of I spotted my different one wasn’t going to attain any issues,” says Ubellacker, who, because it occurs, has stored up the circle of relatives custom — his brother Wyatt received first prize in 2011. “I’ve almost definitely labored about 100 hours this week in this robotic. I’m simply happy that it labored out.”

He credit his luck, and the entire expertise he’s received all the way through the semester, to the entire professionals in the back of 2.007.

“I didn’t know a lot about machining moving into,” Ubellacker says. “Interacting with the machinists and the workforce might be my maximum memorable reviews. They’re all truly cool other people, and so they shared all this information with me. This used to be all truly nice.”
