We’ve seen lots of Segway variants on Hackaday, but they don’t always have detailed instructions on how they made it… Well lucky for us, [Bob] from [Making Stuff] just finished his extensive Segway project with tons of videos of the build!
Inspired by other self-balancing scooter projects he had seen online, [Bob] wanted to try his hand at building one. So he took bits and pieces from designs he liked, and came up with his own solid looking Segway clone design. Using Google Sketchup he drew up the frame, and from there it was all hands on deck. A bit of TIG welding later and it was time for the components.
Some small slight mechanical hiccups aside, the longest part of the project was the electronics and software — getting it to work like a real Segway. After writing his own code he ran into a few roadblocks, but luckily he was able to get some help from someone at his local Maker meetup which saved a lot of troubleshooting on his end.

[Jason Dorie] has been hard at work on his two-wheeled, self-balancing skateboard. He calls it the Sideway.
Similar to the Segway, it relies on the user shifting their weight to control the speed at which it will run. A Wii Nunchuk controller is used to steer, which varies each wheels output, which allows for some tight maneuvering!
Under the deck is a pair of 24V 280W (about 1/3HP each) scooter motors which are driven by two 32A Sabertooth speed controllers. They’re run off a pair of 3 cell 5Ah LiPos which get him about 40 minutes of use — not too shabby! To handle the control algorithm for the IMU, he’s using a Parallax Propeller with custom software.
To demonstrate, he takes us of a tour of one of his favorite stores — Michael’s.

[Renee] dropped a tip to let us know about EddiePlus, her balancing robot creation. As its name might imply, EddiePlus is controlled by an Intel Edison processor. More specifically, [Renee] is using several of Sparkfun’s Edison Blocks to create Eddie’s brain. EddiePlus’ body is 3D printed, while his movement comes from two Pololu DC motors with wheels and encoders. The full build instructions are available as a PDF from [Renee’s] Google drive.
Eddie is able to balance and drive around on two wheels, much like a Segway. Sensor data for balance comes from Sparkfun’s LSM9DS0 based Inertial Measurement Unit (IMU) block. In this new “plus” version of Eddie, [Renee] has added encoders to the robot’s wheels. This makes it easier for him to adapt to changing loads – such as pumping iron (or banana plugs as the case may be). The encoders also help with varying terrain, as [Renee] demonstrates by tilting a board as Eddie drives on it. Eddie’s code is written in C, and available on Github. Controlling Eddie is as easy as sending simple commands via UDP.
As you might imagine, the Intel Edison still has plenty of cycles left over after computing Eddie’s balance. [Renee] uses some of these with a webcam based teleoperation mode.
Click past the break to see Eddie in action!

What happens when you put a telepresence robot online for the world to try out for free? Hilarity of course. Double Robotics is a company that builds telepresence robots. The particular robot in question is kind of like a miniature Segway with a tablet computer on top. The idea is you can control it with your own tablet from a remote location. This robot drives around with your face on the screen, allowing you to almost be somewhere when you can’t (or don’t want to) be there in person.
Double Robotics decided to make one of these units accessible to the Internet as a public demonstration. Of course, they couldn’t have one of these things just roaming about their facility unrestrained. They ended up keeping it locked in an office. This gives users the ability to drive it around a little bit and get a feel for the robot. Of course it didn’t take long for users to start to wonder how they could break free from their confinement.
One day, a worker left the office door cracked open ever so slightly. A user noticed this and after enough patience and determination, managed to use the robot to get the door opened. It appears as though the office was closed at the time, so no one was around to witness the event. A joy ride ensued and the robot hid its tracks by locking itself back in the room and docking to the charging station.
While this isn’t a hack in the typical sense, this is a perfect example of the hacker mindset. You are given some new technology and explore it to the extent at which you are supposed too. After that, many people would just toss it aside and not give it a second thought. Those with the hacker mindset are different, though. Our next thought is usually, “What else can I do with it?” This video demonstrates that in a fun and humorous way. Hopefully the company learns its lesson and puts a leash on that thing.

[Kristian] just put the finishing touches on his full size Segway built from scratch.
Back in 2012, he made a small balancing robot using a gyroscopic sensor and a PID controller — you can see the original post here. The cool thing is, he’s basically just scaled up his original project to create this full-size Segway!
It uses two 500W 24V DC motors (MY1929Z2) on an aluminum check plate frame, with the rest of the structure made from steel plumbing and fittings. What we really like is the steering linkage; similar to a real Segway, you pull the handle in the direction you want to turn. He’s accomplished this by putting another length of pipe parallel to the wheels which is connected by an elbow fitting to the handle bar. It’s supported by two pillow block bearings, and in the back is a fixed potentiometer — when you lean the handle bars one way, the pipe rotates, spinning the potentiometer. To make it return to neutral, he’s added springs on either side.
There’s an impressive build log to go along with it, and a great demonstration video after the break.

There are skateboards, long boards, and snowboards. This was originally a snowboard, but we’re not quite sure how to classify it now… Introducing the Segbot Snowboard.
[Steve Ghertner] has been playing around with accelerometers lately and decided to try making something practical. He’s taken a snowboard and turned it into a two-wheeled, segway-like balancing board. The two parallel wheels are powered individually by 12V scooter motors. An Arduino Uno takes care of processing the data from a MPU-6050, which is a triple axis gyro and accelerometer.
You can control the board by leaning, or by using a small two-button remote. He hasn’t taken it very far out of the lab yet, but plans to after cleaning up the programming a bit.
Stick around for the following video where he explains it at his local hackerspace in Nashville, the Middle TN Robotic Arts Society where members strive to “Control Them (robots) Before They Control You!”

An Octopart for RC equipment
When [Zach] started building a quadcopter he found it very difficult to source the required parts. Thus was born CompareRC, an aggregation of several online RC retailers. There’s over 150,000 parts in the database, all searchable and sortable by lowest price.
Segway iPad Skype teleconferencing robot
It’ll be a while until robots completely eliminate the need for any human interaction, but until then there’s Double. It’s a two-wheeled balancing robot with an iPad dock, controllable via a remote iPad.
Free electronic design
In case you weren’t aware, Fedora has an electronic design distro that includes just about everything needed to build electronic circuits called Fedora Electronic Lab. FEL has PCB designers, circuit simulators, editors for just about everything, and support for PICs, AVRs, and 8051 micros. Thanks for sending this in, [Simon].
Make your own Megadrive ROMs
Last month, [Lee] sent in a build where he connected an Arduino Mega to an old Sega Genesis/Megadrive cartridge. He’s figured out how to read the contents of the cartridge now, allowing you to preserve your 100% complete Sonic & Knuckles / Sonic 3 save for time immemorial.
A surprising amount of graphics tutorials
Here’s a blog post from the lead dev of the Khan CS project.
