Anyone can create a robot with this simple design tool
Making a robot is hard. Don't take my word for it,
take the word of Stelian Coros, assistant professor of robotics at Carnegie
Mellon University. "The process of creating new robotic systems today is
notoriously challenging, time-consuming and resource-intensive," he says. "In
the not-so-distant future, however, robots will be part of the fabric of daily
life and more people -- not just roboticists -- will want to customize
robots."That's why Coros' lab has developed an interactive design tool that
allows both novices and experts to develop customised legged or wheeled robots
using 3D-printed and off-the-shelf components.It's pretty simple to use – scroll
through a library of components and then drag and drop them into the design.
It'll even suggest components that are compatible with each other, automatically
generate structural components, and suggest where actuators should
go.Puppy-botTo test the system, Coros' team – which also included robotics PhD
student Ruta Desai and master's student Ye Yuan – designed several robots and
fabricated two of them, one with wheels and a manipulator arm that can hold a
pen, and a four legged "puppy"-bot.
"The system makes it easy to experiment with
different body proportions and motor configurations, and see how these decisions
affect the robot's ability to do certain tasks," said Desai. "For instance, we
discovered in simulation that some of our preliminary designs for the puppy
enabled it to only walk forward, not sideways. We corrected that for the final
design. The motions of the robot we actually built matched the desired motion we
demonstrated in simulation very well."Ultimately, the team's goal is to make
robotics more accessible to people without a lot of knowledge of the subject.
"This is important because people who play an active role in creating robotic
devices for their own use are more likely to have positive feelings and higher
quality interactions with them," said Coros."This could accelerate the adoption
of robots in everyday life."
