Mara visits CalTech and meets The Riveters – an all-female crew of engineers competing for prime honors in a 3D printed tank battle!
Yearly, the Mechanical Engineering college students on the California Institute of Expertise in Pasadena are challenged to design, construct, and function a fleet of three robotic tanks that may efficiently navigate, management, and defend strategic base positions on a grass course. This yr marked the thirty third Annual Engineering Design Competitors. There have been six groups of 4, and virtually half of the members had been ladies.
Mara was fortunate sufficient to run into The Riveters – an all-female crew of engineers carrying iconic Rosie the Riveter ribbons. The tanks they entered into the competitors had been two-thirds 3D printed masterpieces. The tanks had been all 3D printed in numerous colours to match an iconic feminine trio – The Powder Puff Ladies!
The Riveters!
They used 3D printing primarily for elements that weren’t load-bearing and that might be laborious to machine, just like the motor mounts. Additionally they stored backup prints helpful for on-site repairs in case of collisions on the course. They took full benefit of 3D printing for prototyping and testing their designs as they moved by a number of iterations as effectively.
College students fabricated their tanks utilizing the MAKEiT 3D printers within the Caltech machine store, or the Craftbots within the 3D printing lab, which may also be used for private tasks.
One competitors tank in between battles.
Right here is how the competitors labored: The robots moved out autonomously in the course of the first 40 seconds of the competitors. Then the opponents had been capable of remotely management the robots to maneuver the next targets; traverse and steadiness on a 10-foot seesaw, climb an elevated four-foot platform and push to activate a big button to seize a strategic place. Whereas direct ramming assaults had been in opposition to the foundations, you could possibly shoot Nerf balls at different robots, and if you happen to scored direct hits thrice, the embattled robotic had to return to the beginning.
Most groups operated two tanks at a time, so if one took a spill, they might swap it out for one more one of their fleet.
The superior Tank Wars trophies!
The competitors featured robots with tank-treads or wheels for mobility, large shovels or scoops to launch Nerf balls, and all of the robots had been constructed utterly from scratch – no manufactured elements had been allowed (aside from wiring!).
The design of the robots usually takes about six months – and it offers the groups invaluable expertise in what they’d come up in opposition to within the skilled engineering world. The iterative means of design, fabricate, check, redesign, fabricate and retest simulates typical business cycles. So despite the fact that the top result’s enjoyable and thrilling, the expertise transferring into the ‘real-world’ is invaluable.
The Riveters had been the undefeated champions of this competitors, because of technique, engineering, preparation, design, and creativity. They had been cautious to not over-design, and in reality, scrapped their first design utterly. They designed their tanks to be dependable, and to resist the obstacles on the course and completed two weeks early, so they’d loads of time to follow – and get a very good night time’s sleep the night time earlier than.
All of the wonderful opponents for the 2018 Tank Wars Problem
Congratulations to The Riveters for a stellar efficiency – on Worldwide Ladies’s Day, no much less! Even the mini trophies had been 3D printed on a LulzBot Taz 6. The big trophy is a portion of an precise metal gear which might be handed alongside to subsequent yr’s winners.

Are you utilizing 3D printing for an superior faculty mission? Please go away me a remark – I’d love to listen to about it.
I’m Mara and this has been your MatterHackers Minute. Go be superior!
