Imagine you are traveling the beautiful Icelandic countryside. You and your significant other have found the perfect place for a picture, and you both look stunning that day. But there is no one around to take it for you! You go for the selfie, but your arm just isn’t long enough to do justice to the landscape.

Introducing the Selfiebot! This robot is designed to track faces and take pictures of you and your friends, completely autonomously. The system allows the user to set a number of parameters specifying image properties, centering properties, and photo taking parameters. We used OpenCV running on a laptop computer for image processing and facial detection, and relayed scanning and centering commands to the robot via serial communication to the ATmega 1284 microcontroller.

What is seeing without feeling? The field of Virtual Reality has recently been gaining much attention, with the Oculus Rift and Google Cardboard paving the path of visualizing a world that is not physically there. But what if the virtual reality experience could be enhanced by incorporating tactile sensing? The Haptic Glove we developed accomplishes just that – without seeing the physical structure of the object, you will still be able to feel the presence of virtual objects.

The goal of the project is to create an exoskeleton on the forearm arm that provides tactile perception for the user. The volume of the virtual object will be emulated based on the intensity of a light source that is placed inside a black box. Depending on the relative brightness of the source to the phototransistors that are mounted onto the exoskeleton, a distance between the user’s hand and the light source can be determined. By varying the brightness of the LED light source, the size of the virtual object will vary. To provide the tactile perception, servos mounted on the exoskeleton provides a pulling force, preventing the user’s fingers from reaching closer to the light source. In addition to the resistive force that act against the fingers’ movement, there are also flat surfaces at the tips of the exoskeleton that will flip up to make contact with the user’s fingers, which actually provides the sense of touching a real object.

Piccolo, a pocket-sized stand-alone CNC platform from DiatomStudio:

Using laser-cutting, off-the-shelf hardware and Arduino, you can make your own simple 3 axis robot. Attach a brush or pen to make a quick drawing robot, or extend Piccolo with sensors, custom toolheads, or by using multiple Piccolos together. Experiment with 2D or 3D digital fabrication at a small scale!

I’ve start building multicopters (or drones if you like it better) five months ago! My first one was a scratch build tricopter based on a KK2.1.5 flight controller and three DT750 motors. Everything was made out of plywood and pinewood! It held excellent if you consider that I was a newbie pilot (still I am) and I had something like 3-4 crash reports per flight!

Two moths ago I decided to go a step further and make my second multicopter. This time it will look a little bit more professional than my previous one! To begin with it will be a quad copter, carry a better flight controller, reuse parts of the previous build (in order to lower the cost) and it will be able to stay above the ground longer.

All parts were developed separately. This allowed adjustments in the assembly as well as smaller changes in case the design of one or other part become required.

Focus on low cost and use of materials easily accessible in the local market.

This project describes the design of a very low budget 3D Printer that is mainly built out of recycled electronic components. The result is a small format printer for less than 100$.

First of all, we learn how a generic CNC system works (by assembling and calibrating bearings, guides and threads) and then teach the machine to respond to g-code instructions. After that, we add a small plastic extruder and give an overview on plastic extrusion calibration, driver power tuning and other few operations that will bring the printer to live. Following this instructions you will get a small footprint 3D Printer that is built with about an 80% of recycled components, which gives it a great potential and helps to reduce the cost significantly.

The planterbot is a plant monitoring robot. It uses capacitance for sensing moisture from the plant instead of using the usual soil probe, this means that wires don’t go into the plant. It also detects temperature and light using thermistors and Cds photocells and displays the temperature and light graphically on the front facing LCD.

Nixie, a tiny wearable quadrocopter camera on a wrist band:

Team Nixie is developing the first wearable drone camera, which can be worn around your wrist. The team will be presenting their prototype for the Intel Make It Wearable Challenge Finale on November 3, 2014 in San Francisco.
