While the Segway enjoyed a few years of fame before falling off the radar, [Marcelo Fornaso] is hoping his creation has quite a bit more staying power. Inspired by the Segway’s ability to balance itself, he started thinking about how the concept could be improved. He felt that one of the Segway’s shortcomings arose out of the fact that the base platform was rigid and required the user to lean back and forth outside the device’s frame in order to turn it. He thought that this made the riding experience uncomfortable as well as risked causing the rider to fall over.
His creation, the Tilto, aims to both improve on the turning ability of the Segway while eliminating the need for handlebars. Based on a tilting mountain board design he had been tossing around for a while, the Tilto uses accelerometers and gyros to keep its balance, much like the Segway. His goal was to keep the vehicle balanced while traveling forwards and backwards, but also allowing the device to tilt from side to side without tipping over. This design keeps the rider mostly upright, allowing the user to direct the vehicle by leaning much like you would on a bicycle.
As you can see in the video below, the Tilto works pretty well, even in its prototype form.
Finally, a people mover that lets us get our gangsta lean on!

Who doesn’t love a 12-legged robot, especially if you can ride it around work? You can watch this one running around the patio with rider perched atop it. The machine translation is a bit crude, but it seem this is based on the wicked walking sculptures of [Theo Jansen]. The rider can shift their center of gravity to control the walker, much like a Segway. We’d bet this makes for a rough ride on anything but a smooth level surface, but we’re fine with indoor use only. After all, you’ll need to be close to a charging station as this boasts 45 minutes of juice when transporting a 165 pound operator. See it scurry after the break.

The video above is the final working DIY Segway from [sb-scooter]. The website and build log don’t have a lot of information at the moment, but you can still gawk at several pictures of the construction (and a picture is worth 1000 German words).
For those looking for the nitty gritty, with some quick math we figure its two 500 watt motors, powered by 12Ah batteries, will last about 90 minutes. If you’re looking for more details or to build your own, you’re as lost as we are.
[XenonJon] got a lot of attention for a skateboard/segway style balancing platform he took to the Makerfaire in Newcastle. He decided to try to build it the cheapest and easiest possible way in an attempt to help others build their own. The build is documented very well, however you have to email him to request the code for the Arduino. Maybe after enough requests, he’ll just pop it online. We thought this looked familiar, so we searched the archive and found this very similar setup from back in 2005. Unfortunately, that project page appears to be gone now.
[Mark] wanted a Segway but why buy something if you can have more fun building it? His end product is an amazing homemade version of the self-balancing transportation package. We’ve seen several projects that include auto-balance, but this one is large enough to ride on and has a bit of an advantage in the design. The motors, batteries, and other components are mounted below the wheel hubs and are weight balanced. This means that the device wants to find balance naturally, even when the electronics are switched off.
The frame was modeled in CAD and then welded together. For propulsion [Mark] has installed two 750 Watt motors which will use sprockets and chains to turn the wheels. The machine balances based on data from both a gyroscope and an accelerometer, with the entire packaged tied together using an Arduino.
[Mark’s] build log is well laid out and details each part of the build with a different post. His two most recent entries include video of the unit balancing and of him riding the 95% completed project. A big thanks to [Mark] for taking the time to document this so that we can share in the excitement of a well-executed project.
When [Epokh] sent in this Wii controlled segway style bot, we remembered a post a few months ago where someone made a balancing bot, but hadn’t completed the Wii code. Well, [Epokh] is going to show you how to implement the Wii controls with the Lego NXT system. He’s found the links to all the software you need and broken down the configuration step by step. He’s been busy lately, let’s hope he keeps it up.
[Kerry] is building a segway type vehicle for a senior project. Though it doesn’t appear to be done yet, there is some good work finished. As with any balancing bot, it relies heavily on input from a gyroscope, and at least in this case, an accelerometer. That data can be very messy. The sensitivity of the sensor means that people often end up with vibrating or drifting in their projects. [Kerry] has put some work into finding a method of smoothing that results in fast, accurate, but smooth reaction. You can see a video of some comparisons between methods after the break.
