Introduction “An ultrasonic range-finding hat with variable haptic feedback for obstacle detection.” -Project Sound Bite For our ECE 4760 final project, we designed and implemented an ultrasonic range-finding hat that uses haptic feedback to alert its wearer about obstacles in his or her path. The hat is equipped with an ultrasonic transmitter/receiver circuit, which is capable of …
In this tutorial we are going to interface FLEX sensor with ATMEGA8 microcontroller. In ATMEGA8, we are going use 10bit ADC (Analog to Digital Conversion) feature to do this job. Now the ADC in ATMEGA cannot take a input more than +5V. What is a Flex Sensor? A FLEX sensor is a transducer which changes its resistance when its shape …

A modern microcontroller has almost everything that’s needed to implement a touch sensor matrix. There are several sensing technologies: IC manufacturers typically advise using certain tech, sometimes they offer ready to use hardware- or software-based solutions. I was curious to try to implement a sensor matrix entirely from scratch all by myself. Here’s how it …
Introduction As our final project, we decided to design and build a robot capable of vacuuming the floor of a room or area without any human interaction other than just starting the unit. We realized the need for a cheap and convenient product that can be easily used to vacuum a room on its own, …
Introduction Sensing in autonomous vehicles is a growing field due to a wide array of military and reconnaissance applications. The Adaptive Communications and Signals Processing Group (ACSP) research group at Cornell specializes in studying various aspects of autonomous vehicle control. Previously, ACSP has examined video sensing for autonomous control. Our goal is to build on …

Introduction For our project, we designed a glove that can be used to control the Cornell University robotic Snake arm thereby enabling a surgeon to remotely operate the snakearm as a colonoscope in conjunction with a vision guide system (aka TV goggles). The glove allows for movement of the arm’s segments as a whole and …
Summary We used two stepper motors to drive a steel ball scavenged from a ball-bearing. These motors were controlled by a PS/2 mouse wirelessly using the RCR-433 and RCT-433 receiver/transmission combination mentioned in lecture. We then took the PS/2 protocol, made it compact, modified existing transmission code and deduced a way to control the robot …
Introduction Our project is a twenty four and half inch aluminum frame robotic arm with four degrees of freedom. In our project we made the arm the second player in the classic game of Tic-Tac-Toe to demonstrate its programmable repeatable motion. The arm consists of five servo motors, four to control the motion and one …
Motivation Deciding a direction of the final project in ECE 4760 can be very difficult. With small Micro Controller Unit, we can build anything and everything. We felt compelled to find something very creative and ingenious and had looked around our surrounding and have found something interesting, printer. There is a conventional printer that moves …
Introduction We created a wearable game controller that uses accelerometers to acquire action of the hand and then maps an action to an arbitrary keystroke. The types of actions we are trying to recognize should be suitable as input control for video games. We placed 3 z-axis accelerometers on tips of the thumb, the index …
