Introducing the latest creation from B.O.T, the SWARMµBOT. An Arduino-Compatible educational micro-bot with all sensors required for applications such as Line-Following, Maze Solving, And Swarming! With a Atmega328 running an Arduino-compatible bootloader, and an integrated USB-UART bridge, programming this bot is as easy as connecting a USB cable, and hitting upload.

This pleasant-looking plant may try to take your hand off if you’re not careful. The robot flower (translated) includes sensors that cause the petals to move in reaction to external stimuli.

You can just make out the distance sensors as black rectangles on two of the petals. These let the flower track an object by rotating the flower stem. But if they determine the object is getting a bit too close for comfort, the servo motor on the back of each petal will cause the flower to suddenly clamp shut.

The video after the break starts off with an in-depth look at the hardware that went into the project. An Arduino clone called the GRoboduino makes this project a lot easier since it has a bunch of extras on the board aimed at things like sensors and servo motors. The mounting technique for the petal-powering-servos is quite attractive, and we enjoy the Snapple lid (probably not the actual brand but you get the picture) which has been coated with yellow felt for the center of the bloom. The final look is normal enough to fit in with home decor, but it still has enough geek in it to melt our hacker hearts.

Hey guys, i want to build a line following robot and I was scouring ebay for some sensors

I found these but I wasn't sure if they would work, as I haven't done this before. They're pretty cheap.

Take an e-ink smartwatch that's got plenty of willing customers, throw in a WiFi-connected sensor box and well, imagine the possibilities. The founders behind Pebble and Twine hope you are, because they have announced that the pair will be connectable through the latter's web-based interface. This means you'll be able to setup text notifications to your wrist when your laundry's done, when someone's at your door and plenty more mundane real-world tasks. A brief video explains how it should all go down, but try not to get too excited -- pre-orders are sadly sold out.

In Insert Coin, we look at an exciting new tech project that requires funding before it can hit production. If you'd like to pitch a project, please send us a tip with "Insert Coin" as the subject line.

Fallen out of love with sensor? Don't worry, Variable Technologies is here to help. The company's working to bring the world Node, a project aimed at helping smartphone users "explore the fun and power of sensors." The "Swiss Army knife-sized" modular device communicates with the iPhone 4S and Android devices via Bluetooth. It has a built-in accelerometer, magnetometer and gyroscope and can detect physical motion and space, temperature and elevation, to name but a few. It also has a game control module and eight LEDs that can double as a camera flash, with carbon monoxide and radiation detection on the way. The Node will be compatible with Arduino devices and will have an open API, firmware and source code. There's a month left to help Variable hit its lofty $50,000 goal.

This is one of those simple concepts which makes you think “Why didn’t I think of that?”  The entire sonar unit is attached to a wearable glove and as the user sweeps their arm back and forth, the device can detect anything from one inch to 10 feet in size.

Two servomotors apply pressure to the top of the hand when obstructions are detected. The closer the object is, the more pressure is applied. The response time is in milliseconds, allowing a blind person to navigate easily around obstacles or find items on a table, for example.
