Abstract -A Roomba for boards For our ECE 4760 final project we created a board climbing robot capable of cleaning the board autonomously. The robot uses neodymium magnets to stick to the board and moves across it with two continuous servo motors. It has bumper sensors on all four sides and keeps track of its …
Our project was mainly designed for the Cornell Mars Rover project team (CMR), which will be using the robotic arm for competition to complete many different tasks in the deserts of Southern Utah. For our ECE 4760 final project, we created the control systems for a robot arm that is able to use three different …
Description With this circuit you can drive a unipolar stepper motor. It operates in full step mode. You can get a stepper motor from an old 5.25 disk drive. The AVR attiny2313 micro controller controls the pulses for the stepper motor. The pulses are amplified by the ULN2003 driver. The driver accepts 5V inputs, the output for the driver …

This is the second stepper motor driver circuit I build. The first one had 4 linear current sources and got so hot it was barely usable. It had some cool leds though. When I was searching for a better schematic on the internet I couldn’t find any to my linking. I did find some commercial …

Intro Summary Thinking about what a CDE (culminating design experience) should be, we devised a project that combines the microcontroller programming principles learned in ECE 476: Microcontroller Design with the control theory concepts learned in ECE 472: Feedback Control Systems to create an academically viable stationary helicopter. The device consists of a lever with a …
Introduction The Balance Bot is a singular axis self balancing robot that is capable of adjusting itself to changes in weight and position. We developed the Balance Bot (BB or B2) from a single servo and a single accelerometer. This was very much a proof of concept to show the capabilities of the ATMega644 in …
Background We designed and implemented an automated, portable bird-trapping mechanism, along with an associated system which is scalable Every year between early May and mid-June large amounts of tree swallows migrate to Ithaca, NY area to mate. The study of these birds invariably require a large number of specimens to be captured for purposes such …

With this circuit you can control two unipolair stepper motors in full step mode via the RS232 serial port of your PC. A terminal program such as Hyperterminal can be used to control the stepper motors. The stepper motors can be driven one at a time. Features: Drives two unipolair stepper motors in full step …
Introduction This project uses an Arduino microprocessor and a MAX522 8 bit serial DAC to produce arbitrary low frequency oscillator (LFO) waveforms. These waveforms are useful for driving a tremolo/vibrato circuit in a guitar amplifier such as the Lil Tiger or the Hammonator 2RVT. This is a second generation version of this project, see the first version for reference. The first prototype …
Abstract The automated drink mixer takes orders from a push-button menu, and moves a regular 16-ounce glass under a series of inverted bottles while dispensing specified amounts of mixers to make perfect non-alcoholic beverages. Introduction If you’ve ever been to a crowded bar or restaurant and waited a long time just to get served an ill-prepared …
