"When you make a thing, a thing that is new, it is so complicated making it that it is bound to be ugly. But those that make it after you, they don’t have to worry about making it. And they can make it pretty, and so everybody can like it when others make it after you"
Rick Winscot has been creating a number of small 3D printed robots and animatronic experiments — and created ROB-OB using entirely Adafruit parts! I love his twitter bio: “Has code in brain, soldering iron in hand, Art Blakey blaring in the background…transforms techno babble into reality and is strangely fond of the ellipsis.” You can see a few of Rick’s robotics projects on the Adafruit Learning System here.

Here’s what Erin has to say about ROB-OB: “Rick is always making interesting robots — recently, one of his robots went to CES as a part of the Afinia booth! The LED animations combined with movements is neat to watch. There is always a nice amount of room inside of these robots to add in your own electronics.”
The robot is comprised of about two dozen parts that can be printed on just about any 3D printer that has a 4.5 X 4.5 inch build platform; PLA or ABS is up to you.
I’ve been building stuff like this since I was about ten or so years old… and I love it!
It’s amazing how fabrication techniques have improved in the last few years. Inexpensive hardware, 3D printers, and awesome boutique electronics stores like Adafruit, SparkFun, and Seeed Studio have opened a Pandoras-box of Awesome.
Are you ready to build your robot? Please make sure to read through the entire Instructable before making any purchases – parts are listed throughout.
If you have any questions, let me know – I’ll do my best to help. Want to see ROBOB (ROB-OB) in action?
Here’s what Erin has to say about Poppy: “The design of this humanoid is interesting, and quite different from the normal ‘block’ appearance. On humanoids, knee servos break the most often, and it is accounted for in this robot with the use of springs (also making the leg swing a little different). Will be interesting to see if it helps with knee burnouts. They are researching even more areas, such as the angle of the things on biped locomotion. Very cool project!”
Sho Yoshida has been exploring an Accessory>Shell>Core>Motor (MCSA) modular construction scheme for Shellmo that keeps the system open and hackable to encourage robot lovers to make highly individual Shellmo robots, taking advantage of 3D printing to free their imagination for mechanical elements as well as outer facing and accessories.
Erin had this to say about Shellmo: “This robot is amazingly well-crafted. It is a work of art! The eyes move using muscle wire, since there was no room for a servo. Detail of the red heart inside (did you see it?) is a great touch. The drive train mechanism… so mesmerizing! Hope Shellmo will be at a Maker Faire this year! Very cool!”
Shellmo is an “open robot platform” for enjoying making, by creating a creature like robot with ease.
“Hi. My name is Shellmo. I’m good at crawling on the desk. Nice to meet you !”
Almost all the parts to form the “body” of Shellmo can be made by using 3D printer.
…At the time being, the most infallible method for manufacturing the “body” of Shellmo is using such 3D printing service as Shapeways. However, I felt that this method alone would not be sufficient to enable more people to use Shellmo with ease. I am now engaged in the project to make Shellmo with a desktop 3D printer. By making it possible to make Shellmo at home, the speed of development will be improved substantially, thereby the cost of manufacturing the parts will be kept under 1/10 of the current cost….
Here’s what Erin has to say about it: “Favorite thing about this robot is that it works with techninja42’s software ‘cncserver’. Making it a great low-cost and DIY alternative to the WaterColorBot. I’ll be using it with the iPad app I wrote.”
This is a small DIY 3-axis CNC. It basically consists of 8 plastic parts (1 part is duplicated, so only 7 unique parts), three micro servos. You will also need 1 zip tie, 1 rubberband, and a pen of your choice.
How to Build a Tiny 3-Axis CNC Drawing Robot
The Tiny 3-Axis CNC robot is a cheap, easy to build, extremely minimalistic but very capable little robot.1 This is the assembly guide for the version 0.29 robot available for download from Thingiverse. The above picture shows the fully assembled robot. If you have ever put together a lego set or built anything from Ikea, you should be able to build the entire robot in less than 5 minutes. I’ve uploaded step-by-step photographs with each “step” organized into a short slide show of pictures.
Here’s what Erin has to say about BoB: “There are many BoBs out there. Easy print to make a fun, little, robot! Its robo-personality can be emitted not only through its appearance, but gait as well. A fun challenge would be to see if you can network them together to form swarm behaviors! BoBoBoBoB … There’s also FrankenBoB and BoBette!”
this is BoB, my version of the 4 dof mini biped.
his goal in life is to walk around and take over the world one 3d printer at a time.
at this time the 1st prototype is under construction. the plans are to use a ping for vision, dagu mini driver for a brain, and 4 9g micro servos to shuffle around.
my real goal with this is to see people build and release their own bobs and make their own add ons.
I’m very pleased to share a selection of inspiring 3D printed robotics projects recommended by Erin RobotGrrl, who was the first to speak up and tell me, “Hey, there are more great 3D printed robots!” after the wrap up of my short survey of 3DxRobotics examples last November. Well, I challenged her to come up with a list of ten good examples, and she quickly sent me twelve!
To kick off the series, here’s my chance to highlight one of her own 3D printed robotics projects, Botbait, which draws together a number of experiments she has been making with both 3D printed robotics solutions as well as 3D design tools:
Tentacle Mechanism Animatronic Robot
This robot is a great way to dive into the world of animatronic tentacle mechanisms and explore different ways of interacting with a robotic creature.
Also known as Botbait, this robot moves organically, lights up charismatically, and enjoys interacting with you.
Available as a kit, a kit including electronics, and customised & assembled.
A soft, wearable device that mimics the muscles, tendons and ligaments of the lower leg could aid in the rehabilitation of patients with ankle-foot disorders such as drop foot, said Yong-Lae Park, an assistant professor of robotics at Carnegie Mellon University.
Park, working with collaborators at Harvard University, the University of Southern California, MIT and BioSensics, developed an active orthotic device using soft plastics and composite materials, instead of a rigid exoskeleton. The soft materials, combined with pneumatic artificial muscles (PAMs), lightweight sensors and advanced control software, made it possible for the robotic device to achieve natural motions in the ankle.
Among the innovations in the device are sensors made of a touch-sensitive artificial skin, thin rubber sheets that contain long microchannels filled with a liquid metal alloy. When these rubber sheets are stretched or pressed, the shapes of the microchannels change, which in turn causes changes in the electrical resistance of the alloy. These sensors were positioned on the top and at the side of the ankle.
According to BBC News, robots could soon be sharing information with each other over their own world wide web.
A world wide web for robots to learn from each other and share information is being shown off for the first time.
Scientists behind RoboEarth will put it through its paces at Eindhoven University in a mocked-up hospital room.
Four robots will use the system to complete a series of tasks, including serving drinks to patients.
It is the culmination of a four-year project, funded by the European Union.
The eventual aim is that both robots and humans will be able to upload information to the cloud-based database, which would act as a kind of common brain for machines.
“At its core RoboEarth is a world wide web for robots: a giant network and database repository where robots can share information and learn from each other,” said Rene van de Molengraft, the RoboEarth project leader.
One robot will upload a map of the room so that others can find their way around it, others will attempt to serve drinks to patients.
“The problem right now is that robots are often developed specifically for one task,” he said.
“Everyday changes that happen all the time in our environment make all the programmed actions unusable.”
The aim of the system is to create a kind of ever-changing common brain for robots.
“A task like opening a box of pills can be shared on RoboEarth, so other robots can also do it without having to be programmed for that specific type of box,” he added.
A new work in production will be an artificial continuously changing environment based on trash, salt, human will and hot water bathing. The piece will consist of a few tons of salt. There will be a mechanism that will be suspended by four cables. By varying the length of the four cables the mechanism will be able to move to most locations within the room. The mechanism will have the ability to extrude crude representations of average objects from salt. These objects will be things like old chairs, toilets, tires, washing machines and many other human specific objects we take for granted as part of our world. The viewer will be able to view these objects being created from the comfort of a hot water tub.
We as a collective species are continually reshaping our world to suit us. We are filling it with things that have importance and meaning to us. While we strive for permanence thankfully the mechanisms that govern the universe beg to differ. Things we make are not permanent and forces beyond our control are constantly making simple the complex objects we devote ourselves to. This piece will be a reflection of that process abstracted and combined with processes of geology. Things will appear that look like things we recognize but due to the fragility of the salt crystals used to make the piece things will be deteriorating at the same rate they are built.
The piece is an attempt to create a vantage point that is impossible in the real world. A vantage point that both condenses and speeds up time and provides an abstracted overview of the detritus we value.
Meet RoboSimian, the Jet Propulsion Laboratory’s official entry at the DARPA Robotics Challenge in December 2013. Also known as “Clyde,” the robot is is four-footed, but can also stand on two feet. It has four general-purpose limbs and hands capable of both mobility and manipulation. It came in 5th place out of 16 entries. See RoboSimian in action at the disaster-response competition. Challenges includes turning a valve, traversing uneven terrain, clearing debris, opening and passing through doorways.
Esko Bionics aims to get 1 million paralyzed people walking again by 2022. Via The Verge.
Robotic exoskeletons are a staple of sci-fi, pointing to a future where technology can overcome serious injury and bestow superhuman powers on people. But that future is here today for Paul Thacker, who uses an exoskeleton about once a month to stand up and walk around — no small feat, considering he’s paralyzed from the chest down.
The 39-year-old Alaska native and snowmobile enthusiast lost the use of his lower body in a training accident in 2010 and was told he’d be confined to a wheelchair, potentially for the rest of his life. But while in physical therapy at a Colorado hospital in 2011, he stumbled across the Esko, a full-body, powered exoskeleton that is the signature product of Ekso Bionics, a Bay Area-robotics company.
“It’s basically a wearable robot,” Thacker says after taking a walk in the Ekso this week at CES 2014 to promote the system. Ekso just unveiled its fourth and latest variant — the more adaptable Ekso GT, last month. “It’s just an incredible piece of technology.” Thacker controls the suit’s mobility through buttons on his crutches, and then sensors and battery-powered joints do the rest. The suit takes about an hour to charge and offers three hours of battery life for walking around and standing upright. And while Thacker can’t exactly run in it and uses crutches to maintain his balance, the suit allows his normally motionless legs to propel him anywhere he wants. For Thacker, it’s as much a form of mental therapy as it is physical.

As in for actual humans, not LEGO minifigs. (Though I wouldn’t put it past him to keep scaling up his minifig project!)
Check out work towards the rear suspension (above) and the differential from the transmission below!
Dec 31, 2013: Update on my 3d printed vehicle project. Finished building the Rear Suspension test rig today. Next up is load testing, then on to designing some CV joints and driveshafts. Printed in PLA on two Makerbot Replicators. The parts are all printed at the default medium settings (2 shells, 10% density, .2mm layer height) except for the blue pins, which are printed at 20% density with 4 shells.
Dec 14, 2013: Bench Test of my 3d Printed rear differential. Printed on a MakerBot Replicator 2 at Medium settings: 2 shells, 0.2mm layer height, and 10% infill density. The buckets have a combined weight of 70 pounds (30 kilos). At the end the chain slips off sprocket and got twisted, with ended testing for the day.
