[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.

Wii Controlled Segway Style NXT Bot

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.

Segway And Input Filtering

[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.

Arduway: A Mini Segway Using The Arduino

October 1, 2008 by 11 Comments

[Joe L] sent in the Arduway on the tipline. It is a robot made of Arduino and Lego NXT components based on the Segway. A software library to control LEGO NXT motors and a few sensors he used is available on SourceForge. This robot does a good job of balancing itself while moving forwards and backwards.

There is a YouTube video of it in operation after the break.

The Woz Playing Segway Polo

April 24, 2006 by 14 Comments

I admit it. Most the weekend I was making quips about the Segway polo guys like, “Those guys look like walking would do them some good, especially that one.” Well, Will and I finally put two and two together and realized that “that one” was Steve Wozniak, co-founder of Apple. He is feared on the polo ground because he has got at least three backups with him and doesn’t mind breaking one.

The Poor Man’s Segway

Skate Segway

Well, maybe it’s not entirely a Segway, but it’s the right idea. these ubc students went and drew up the plans for a skateboard based segway-like vehicle. they dubbed it “emanual” after the skateboard trick called the manual (come on, you at least played tony hawk for playstation right?). they awesome part is that it works. took a few years, but hey, good things take time. it uses electronic tilt sensors to keep you from falling over and has it’s own control system.

thanks [DBS]

Fast Charging A Cargo Bike From An Electric Car Charger

September 18, 2023 by 15 Comments

Fast charging is all the rage with new electric cars touting faster and faster times to full, but other EVs like ebikes and scooters are often left out of the fun with exceedingly slow charging times. [eprotiva] wanted to change this, so he rigged up a fast charging solution for his cargo bike.

Level 2 electric vehicle chargers typically output power at 7 kW with the idea you will fill up your electric car overnight, but when converted down to 60 V DC for a DJI Agras T10 battery, [eprotiva] is able to charge from 20% to 100% capacity in as little as 7 minutes. He originally picked this setup for maxing the regen capability of the bike, but with the high current capability, he found it had the added bonus of fast charging.

The setup uses a Tesla (NACS) plug since they are the most plentiful destination charger, but an adapter allows him to also connect to a J1772 Type 1 connector. The EV charging cable is converted to a standard 240 V computer cable which feeds power to a drone charger. This charger can be set to “fast charge” and then feeds into the battery unit. As an added bonus, many chargers that do cost money don’t start charging until after the first five minutes, so the bike is even cheaper to power than you’d expect.

For some reason, you can watch him do this on TikTok too.
