On the whim of a coin flip, Nick Thatcher once decided between building a homemade Segway, or a self balancing unicycle. Even though the powers of fate chose the former, Thatcher's thirst to build wasn't quenched -- he built the one-wheeled scooter anyway. The Raptor looks a lot like a Ryno unicycle built from spare parts -- a chain driven wheelbarrow wheel powered by a 350w geared motor, a pair of batteries wired in series, some PVC and polycarbonate, an IMU gyro and an Arduino UNO -- all hobbled together to form a one-wheeled electric mount. Thatcher says the scooter can push 10mph safely, but faster speeds tend to outpace the gyro's corrective efforts. Still, the bike promises between 90-120 minutes of face-plant free fun, provided the rider is at least a little balanced. The motorized unicycle isn't for sale, but peek on over to Thatch Industries for a parts list, or scoot on past the break to see the bike in action.

Another interesting project by [nickatredbox], you can find this and all others on the [website].

This project is a plane with the Arduino Xbee remote control working on its maiden flight. It worked well no technical issues, very happy with the results

Building the controller was a very interesting curve, learned a lot of practical usage solutions to problems and ended up with a simple piece of code which is always good in my experience, keep it simple but not to simple.

Here is the GDR Mk 2. I've recycled the parts from the GDR Mk 1 and made some additions/upgrades:

- Built a body for the robot out of a couple of storage boxes

- Added a 2 POF Turret to the top

- attached a laser pointer to the turret and programmed it to aim and fire

- split the power so there is now dedicated power to the motors.

hi folks, I am trying to build an autonomous car by attaching my arduino uno r3  to my rc car. Please pardon me if there are certain stuff I don't understand as my electronics knowledge has long vaporised since my education days and im starting from zero again.

In particular, i'm using this guide http://www.instructables.com/id/Autonomous-Control-of-RC-Car-Using-Arduino/?ALLSTEPS as my RC car is also using a RX-2B chip.

This is BrutBot.

He is my first robot and is based on the Arduino UNO with the Adafruit motor shield and a Parallax ping))) sensor.  I started with a "start here" kit but grew impatient with fried picaxe chips and infrared sensors, so I decided to try Arduino with an ultrasonic sensor instead.

Hi all! First robot ever, saying it's not great would be an euphemism, nevertheless I would be very glad to get some feedback from you.

How it works : two switches on the front, when it meets a wall, andrew goes backwards and turn, then turn the other direction and goes forward again (see video - about the video, sorry for the poor quality, I had to use a phone, I can post a better one next weekend)

Overview

We are building this robot with my friend. It is (when finalized) supposed to be able to detect metal objects and interact with them (move them, ideally...). So far it has only two IR sensors for obstacle detection, so no metal detection.

It's great to see Ben Heck focus his efforts of do-gooder projects like that foot-controlled wheelchair, but we'll always have a soft spot for the modfather's more nostalgic undertakings, like this BASIC pocket computer. Heck created the device for the latest episode of his web show, and if you're following along at home, you'll need the Chatpad from an Xbox 360 controller, an Arduino Uno and a LCD display -- a Hitachi HD 44780, in this case. The modder-turned-host is quick to point out that the project's purpose isn't solely nostalgic -- you can also use it to control real world objects, which in the Heck's case means a ghost on a pinball playfield. Check out a video of the invention in action after the break.

Hobbyist Erik Kettenburg was concerned that the size and cost of Arduino stifled his ability to craft, so he set about developing Digispark. It's an Arduino-compatible board, the size of a quarter, that offers a few pins at around a third of the cost of an Uno -- so you don't have to worry about taking projects apart when you're done. Designed to be fully compatible with the Italian standard, it's packing six I/O pins, 8k memory and a full USB connection amongst other things. The aim is to retail the gear for $12 a piece, and has been so popular that it's made nearly $100,000 in Kickstarter pledges, smashing its original goal of $5,000. We've got video for you below, and you can still throw some cash Mr. Kettenburg's way if you fancy getting your hands on one quickly.

This is the tank. One day, perhaps it'll earn itself a real name.

Being my first robot, it is of course a skid-steering obstacle avoider. Since I already had an Arduino and wanted to continue with it, I didn't follow the Start Here robot, but instead pretty much copied LarryBot. It is made of: a Tamiya 70097 twin-motor gearbox, a Tamiya 70100 track and wheel set, an Arduino Uno and an SN754410 H-bridge chip.
