2018’s Most Advanced 3D Printed Robots & Best DIY Projects

Watch a 3D printed robot in action! Here are the world's most advanced 3D printed robots (incl. videos) and the best DIY projects you can try at home.

It so happens that 3D printing is a wonderful application for the discipline of robotics. It provides designers with the freedom to add new functionality to their creations. That, and end users can customize a robot for their specific uses.

The first section of this article is a round-up of the most impressive and advanced 3D printed robot projects from around the world. Ranging from humanoid robots to four-legged robots to even insectoid automatons, the field of robotics is booming thanks to additive manufacturing.

In the second section of this article, we cover some of the more modest — yet still impressive — 3D printed robot projects that you can try at home. You’ll need the right tools and bill of materials to make them, as detailed in each project, but the thing they all have in common are 3D printed components.

All hail our new 3D printed robot overlords!

3D Printed Robots: The Most Advanced

These are the most advanced 3D printed robots developed so far, with technological breakthroughs and designs only made possible through a combination of 3D modeling software and additive manufacturing.

1

3D Printed Robot Kengoro the Robot That Sweats

Devised by researchers at the University of Tokyo, Kengoro is an advanced 3D printed robot that’s utterly unique. How? It sweats. Specifically, it has a cooling system that mimics a human sweat gland. So when doing a strenuous physical like activity push-ups, for example, it perspires to cool itself down.

A creation like Kenjaro is only possible thanks to additive manufacturing. With 108 motors, the robot needs an efficient cooling system. But adding another mechanical part inside the robot also means adding more mass and weight. Not desirable if you want to keep your machine lean and mean.

The solution lies in Kengoro’s frame, which is constructed from selectively laser sintered aluminum powder. By altering the energy density of the laser during fabrication, the permeability of the metal can be customized with areas of both low and high permeability. In effect, seamless metal components with microchannels embedded in them through which water can flow.

3D Printed Robot Octobot

The field of soft robotics are having quite a few Eureka moments thanks to additive manufacturing. This advanced 3D printed robot takes the form of an octopus. The Octobot has no rigid components, and its body is composed from 3D printed silicone.

How does the Octobot even move? The answer is gas. As in, breaking wind. Instead of electricity or batteries, this 3D printed robot is powered by a pneumatic system; a chemical reaction occurs when fuel meets the platinum ink, creating a gas that makes the soft robot move its tentacles.

3D Printed Robot BionicANT

These small 3D printed robots look and behave just like real ants. Except the BionicANT is a little bit bigger, and it’s probably not interested in your jam sandwiches when you go on a picnic.

Developed by German company Festo, “ANT” here refers to “Autonomous Networking Technology”. Each BionicANT has a camera and sensors that enables it to locate an object and communicate with other BionicANTS in the immediate vicinity.

The 3D printed robots can then team up, coordinate their actions, and move objects together. It’s pretty impressive. And a little frightening. But mostly impressive.

3D Printed Robot Robirds

Did you think that scarecrows were the height of bird aversion technology? Think again, straw-man.

This is a 3D printed robot bird from Dutch company Clear Flight Solutions. It’s designed to keep air space clear of birds in flight critical areas, like an airport runway, by frightening away their live counterparts.

These 3D printed robirds are effectively drones that can fly by flapping their wings, and are camouflaged to appear like real birds. Additive manufacturing has proven especially useful here, providing design freedom to engineers who seek to bring complex ideas to life.

3D Printed Robot InMoov

InMoov is a life-size 3D printed robot created by Gael Langevin, a French sculptor and designer. This automaton is a spectacular achievement, not just because of its size but also because of its fluid and graceful articulation, right down to its fingertips.

The open source project is envisaged as a development platform for students, makers and academics. The hand of this model, which first appeared in 2012, also carries the distinction of being the first open source 3D printed hand prosthetic.

6

3D Printed Robot ASPIR

This is another open source 3D printed robot, ASPIR, which stands for “Autonomous Support and Positive Inspiration Robot”.

This humanoid automaton is highly maneuverable. It uses six supersize servos per leg, four high-torque standard servos for each arm, five metal-gear micro servos for each hand, and two additional standard servos for the head’s pan/tilt mechanism.

Each of the 90 parts that make up it’s body will take roughly 300 hours of 3D printing. You can find the full tutorial and bill of materials over on Instructables.

3D Printed Robot OpenCat

Rongzhong Li is an assistant professor at Wake Forest University in North Carolina, and creator of an open source 3D printed robot cat. After OpenCat was featured on IEEE Spectrum’s weekly roundup of robot videos, he’s been flooded with possibilities for the future development of his personal project.

On his Hackster page he explains that the project started in Summer 2016. Since then, the cat has gone through seven iterations, each one increasingly more complex. The latest one in the video dates from September 2017.

Currently, Li has two working models. A smaller one targeted at STEM education and the maker community that runs on an Arduino module. And a larger model with a Raspberry Pi for AI-enhanced perception. He’s looking for funds to evolve OpenCat into a collaborative project, and eventually a mass-produced product.

3D Printed Robots: The DIY Projects

With a bit of soldering and wiring, these 3D printed robots are actually capable of movement like dancing or walking. They’re fantastic weekend projects, and thoroughly educational to boot.
