“Question: What makes 8 times ‘beep’, but cannot be heard?
Answer: My ultrasonic range finder 🙂 ~ FRDM-KL25Z with HC-SR04. What I’ve added to my FRDM-KL25Z board is an ultrasonic distance sensor, measuring distances up to 4 meters.”

Don’t miss this thorough tutorial on using and interfacing ultrasonic range finders to microcontrollers.

“The Finch is a new robot for computer science education. Its design is the result of a four year study at Carnegie Mellon’s CREATE lab. The Finch is designed to support an engaging introduction to the art of programming. It has support for over a dozen programming languages and environments, including several environments appropriate for students as young as eight years old.”

“Our group designed and manufactured a miniature robotic vehicle that conquers various terrains. The vehicle was designed with a track system which is powered by two DC motors. The motors use a Quadruple half H-Driver in order to drive the motors in both directions….These configurations allow the vehicle to drive on various terrains. ”

“The CHORG project consists in both a hardware and software platform both of them developed by myself. The main purpose of this project is to create a robot arm capable of adapting a task to randomness of the real environment. While the hardware’s imperfections serve as good way measure the randomness the software purpose is to adapt that and allow it to successfully perform a certain task.”

“This website describes an open design for a small, $800 robot suitable for swarm-style multiagent research, robotics education, and other tasks. Our goal is to get as much functionality as possible from $800 per robot, replicate the robot many times to create a small collaborative swarm, and document the results to make it easier for you to do the same.”

“Felix is one of the first robots I created using the kinect sensor. Felix uses NPC Robotics 24V Electric Gear Motor Set – R81, R82. they are basically wheelchair motors. With 10? solid wheels and custom aluminum hubs. For the Robot Stroller kit I use 2 of the Jazzy Select Elite, Coupled with 2 of the 12 inch tires.”

“The E-bike computer. It gives me different information about the bicycle like: battery voltage, external temperature, temperature of the battery, speed and distance traveled. There is also a throttle and state of charge indicator. This is how I accelerate the bicycle giving the input to the motor to move forward.”

“In this article, we will go step-by-step through the process of understanding, designing and building a system that uses an infrared proximity sensor for input, correlates that input to how far away an object is from the sensor and then drives a motor and some LEDs at distinct speeds depending upon the proximity of the object.”

“HiJack is a hardware/software platform for creating cubic-inch sensor peripherals for the mobile phone. HiJack devices harvest power and use bandwidth from the mobile phone’s headset interface. The HiJack platform enables a new class of small and cheap phone-centric sensor peripherals that support plug-and-play operation.”
