Turn Your Teddy Bear Into A Robot With Yale’s “Robotic Skin”

Despite what we may have seen in the new Winnie the Pooh movie, our cherished plush toys don’t usually come to life. But if that’s the goal, we have ways of making it happen. Like these “robotic skins” from Yale University.

Each module is a collection of sensors and actuators mounted on a flexible substrate, which is then installed onto a flexible object serving as structure. In a simple implementation, the mechanical bits are sewn onto a piece of fabric and tied with zippers onto a piece of foam. The demonstration video (embedded below the break) runs through several more …read more

Electric Wheelbarrow Makes Hauling Big Loads Easier

Gardening involves a depressing amount of physical activity: haul this over here, dump it there and then cover it with this. Things like wheelbarrows are still damn hard work, especially for people like who are somewhat physically compromised. That’s why we love this build from [Karl Gesslein]. He usually makes electronic bikes, adding motors to bicycles to roam the streets faster. But this time he applied his expertise to a wheelbarrow. He added a 3000W motor to the wheelbarrow, which drives the front wheel when triggered by the accelerator on the handle.

The project is a bit more sophisticated than …read more

Robotic Fruit Fly Won’t Eat Your Fruit

The DelFly project has been busy since the last time we checked in on them. The Dutch team started 13 years ago and produced the smallest camera-carrying drone, and an autonomous tiny ornithopter. However, that ornithopter — now five years old — had to use some traditional control surfaces and a tail like an airplane which was decidedly not fruit fly-like. Now they’ve solved those problems and have announced the DelFly Nimble, a 13 inch and 1-ounce ornithopter. You can see the Nimble in the video below.

The close emulation of a real fly means the thing looks distinctly insect-like …read more

iCub is the Robot that is Equally Cute and Creepy

We shouldn’t say iCub — the humanoid robot from Italy — is creepy. After all, human-like robots are in their infancy and an early computer or automobile would hardly be indicative of where those industries would take us. You can see the little guy in the video below.

The effort is open source and was part of an EU project that has been adopted by 20 labs around the world. The video just shows a guy in VR gear operating the robot, but the website has a lot of technical information if you want to know more.

The robot has …read more

Cat Robot’s Secret to Slim Legs? Banish the Motors!

The first thing to notice about [Bijuo]’s cat-sized quadruped robot designs (link is in Korean, Google translation here) is how slim and sleek the legs are. That’s because unlike most legged robots, the limbs themselves don’t contain any motors. Instead, the motors are in the main body, with one driving a half-circle pulley while another moves the limb as a whole. Power is transferred by a cable acting as a tendon and is offset by spring tension in the joints. The result is light, slim legs that lift and move in a remarkable gait.

[Bijuo] credits the Cheetah_Cub project as …read more

The Tiny, Pocket-Sized Robot Meant For Hacking

The world is full of educational robots for STEAM education, but we haven’t seen one as small or as cute as the Skoobot, an entry in this year’s Hackaday Prize. It’s barely bigger than an inch cubed, but it’s still packed with motors, a battery, sensors, and a microcontroller powerful enough to become a pocket-sized sumo robot.

The hardware inside each Skoobot is small, but powerful. The main microcontroller is a Nordic nRF52832, giving this robot an ARM Cortex-M4F brain and Bluetooth. The sensors include a VL6180X time of flight sensor that has a range of about 100mm. Skoobot also …read more

Flexible PCBs Make The Fins Of This Robotic Fish

We love a little outside-the-box thinking around here, and anytime we see robots that don’t use wheels and motors to do the moving, we take notice. So when a project touting robotic fish using soft-actuator fins crossed the tip line, we had to take a look.

It turns out that this robofish comes from the fertile mind of [Carl Bugeja], whose PCB motors and flexible actuators have been covered here before. The basic concept of these fish fins is derived from the latter project, which uses coils printed onto both sides of a flexible Kapton substrate. Positioned near a magnet, …read more

Shoelace-Tying Robot With Only Two Motors

Many things that humans do are very difficult for machines. Case in point: tying shoelaces. Think of the intricate dance of fingers crossing over fingers that it takes to pass off a lace from one hand to the other. So when a team of five students from UC Davis got together and built a machine that got the job done with two hooks, some very clever gears, and two motors, we have to say that we’re impressed. Watch it in action on Youtube (also embedded below).

The two-motor constraint would seem at first to be a show-stopper, but now that …read more

ESP8266 Powered Tank With Voice Control

The high availability of (relatively) low cost modular components has made building hardware easier than ever. Depending on what you want to do, the hardware side of a project might be the hacker equivalent of building with LEGO. In fact, we wouldn’t be surprised if it literally involved building with LEGO. In any event, easy and quick hardware builds leave more time for developing creative software to run the show. The end result is that we’re starting to see very complex systems broken down into easy-to-replicate DIY builds that would have been nearly impossible just a few years ago.

Robots Invade Your Personal Space

If you have ever had to complete a task such as building a LEGO model over a remote connection, you will know that the challenges are like an absurd grade school group project. The person giving directions often has trouble describing what they are thinking, and the person doing the work has trouble interpreting what the instructor wants. “Turn the blue block over. No, only half way. Go back. Now turn it. No, the other way. NO! Not clockwise, downward. That’s Upward! Geez. Are you even listening‽” Good times.

While you may not be in this situation every day, the …read more
