Adorable Quadruped Robot Hops And Walks

The ESP8266 is finding its way into all sorts of projects these days. It’s a capable little device, to be sure, but we’d have to say that finding it running a quadruped robot that can hop and run was a little unexpected. And to have it show up in such an adorable design was pretty cool too.

From the looks of [Javier Isabel]’s build log, he put a lot of thought into [Kame]. All the body parts and linkages are 3D printed from PLA, with the nice touch of adding a contrasting color. The legs are powered by eight high-speed Turnigy servos, and good quality bearings are used in the linkages. A NodeMCU runs the show with custom oscillator algorithms that control the various gaits, including the hopping motion. The BOM even lists “Adhesive 12mm diameter eyes” – perhaps that’s some sort of slang for the more technically correct “googly eyes.”

Built primarily as a test platform for studying different gaits, there doesn’t seem to be much in the way of sensors in [Kame]’s current incarnation. But with an ESP8266 under the hood, the possibilities for autonomous operation are good. We look forward to seeing where this project goes next. And we kid about the cuteness factor, but never doubt the power of an attractive design to get the creative juices flowing.

We’ve covered a lot of quadruped robots before, and a lot of them seem to trend toward the cute end of the spectrum. Check out this baby-quad that’s learning to walk or this quad that thinks it’s a puppy.

Open Furby Opens The Furby

Remember Furby? The cute reactive robot was all the rage a few years ago, when the strange chattering creature was found under many a Christmas tree. Most Furbys have been sadly neglected since then, but the Open Furby project aims to give the toy a new lease of life, transforming it into an open source social robot platform.

We’ve featured a few Furby hacks before, such as the wonderful Furby Gurdy and the Internet connected Furby but the Open Furby project aims to create an open platform, rather than creating a specific hack. It works by replacing the brains of the Furby with a FLASH controller that runs the Robot Operating System (ROS), making the Furby much easier to program and control. They have also replaced the eyes with small OLED screens, which means it can do things like show a weather forecast, facebook notification, etc.

It is still in the early stages, but it looks like an interesting project. Personally, I am waiting for the evil Furby that wants to kill you and eat your flesh with that nasty beak…

Warbots: Is It Already Too Late?

In 1971, a non-profit formed that holds the World Economic Forum each year. The Forum claims it “Engages the foremost political, business and other leaders of society to shape global, regional and industry agendas.” This year, the Forum hosted a session: What If: Robots Go To War? Participants included a computer science professor, an electrical engineering professor, the chairman of BAE, a senior fellow at the Vienna Center for Disarmament and Non-Proliferation, and a Time magazine editor.

It’s A Bird, It’s A Plane, No… It’s High Voltage EPROM Man!

At Hackaday, we cover some pretty high-tech builds. Sometimes, though, you see something simple, but it still makes you feel happy to see it. That’s pretty much the case with [ProtoG’s] High Voltage EPROM Man.

The parts probably came out of a junk box, but the good news is that they don’t have to work, and you can freely substitute anything you have. According to [ProtoG], the “robot” head is a bulb socket with a crystal for the visor. The arms are fuses with fuse clips for the hands. The knees are adjustable caps, and the feet are TO-220 transistors.

How To Use Lidar With The Raspberry Pi

The ability to inexpensively but accurately measure distance between an autonomous vehicle or robot and nearby objects is a challenging problem for hackers. Knowing the distance is key to obstacle avoidance. Running into something with a small robot may be a trivial problem but could be deadly with a big one like an autonomous vehicle.

My interest in distance measurement for obstacle avoidance stems from my entry in the 2013 NASA Sample Return Robot (SRR) Competition. I used a web camera for vision processing and attempted various visual techniques for making measurements, without a lot of success. At the competition, two entrants used scanning lidars which piqued my interest in them.

Robots And Crickets

If you watch science fiction movies, the robots of the future look like us. The truth is, though, many tasks go better when robots don’t look like us. Sometimes they are unique to a particular job or sometimes it is useful to draw inspiration from something other than a human being. One professor at Johns Hopkins along with some students decided to look at spider crickets as an inspiration for a new breed of jumping robots.

Robotic Suitcase Follows You Around

I have something that follows me around all the time: my dog Jasper. His cargo-carrying capability is limited, though, and he requires occasional treats. Not so this robotic suitcase. All it needs, the designers claim, is an occasional charge and a Bluetooth device to follow.

Designed by NUA Robotics, this suitcase is equipped with powered wheels and a certain amount of smarts: enough to figure out the direction of a Bluetooth signal such as your cell phone and follow it. This is also accompanied by proximity sensors so it doesn’t bump into you or other people. When the built-in battery runs out, just pop put the handle and pull it yourself, and the regenerative motors will recharge the battery. There’s no indication on price, battery life or how much space is left to actually carry stuff yet, but the designers claim it could be out within the year. As someone who uses a walking stick, this sounds like a great idea. And if they can work out how to get it to walk the dog for me, that would be even better.

Now, who will be the first to build a clone of this in their basement? Bonus points if it’s a two-wheeled self-balancer.
