A new 3D-printed robot called Poppy is helping a team of French researchers study bipedal walking and human-robot interaction. They were able to design, fabricate, and assemble a relatively large robot for around €8,000 (US$11,000) including servo motors and electronics. That's about a third the cost of commercial robots in the same size category like the RQ-TITAN, and is still cheaper than smaller humanoids like the Aldebaran Robotics NAO. And best of all, they plan to make their design open source.
One of the ways they managed to keep the cost down is by using lightweight materials, which means the robot requires less powerful (and cheaper) servo motors. Standing 84 cm (33 in) tall, Poppy weighs in at just 3.5 kg (7.7 lb). The Sony QRIO, by comparison, was 26 cm (10 in) shorter yet it weighed twice as much. Still, most of the cost lies in the robot's 25 servo motors: it utilizes 21 high-end Robotis Dynamixel MX-28s, two MX-64s, and two AX-12s. It's powered by a Raspberry Pi, and is equipped with 16 force-sensing resistors, two HD cameras, a stereo microphone, and an inertial measurement unit. Poppy's "face" is an LCD screen which can be used to show emotions (or to debug).

"3D printing hardware is rapidly scaling up to output continuous mixtures of multiple materials at increasing resolution over ever larger print volumes. This poses an enormous computational challenge: large high-resolution prints comprise trillions of voxels and petabytes of data and simply modeling and describing the input with spatially varying material mixtures at this scale is challenging. Existing 3D printing software is insufficient; in particular, most software is designed to support only a few million primitives, with discrete material choices per object..."

Tweet Tweet 3D printers have been around for a while now. Their prices are slowly coming down. Some people are still not sure what they can do with a 3D printer though. 3D printers can print food, human tissue, plastic, and other material. Via António Gonçalves, juandoming
