Final Projects ECE 4760. Your DIY Educational Robotic Pet! Omnix Technology, Inc. - Directional Components & Integrated Systems. Omnix utilizes top rated drive systems, such as a hydraulic drive system or a battery powered electric motor drive system that allows for maximum performance for every omni-directional transporter. The main parts of an omni-directional drive system are comprised of the following: wheels, gear reduction, and motors. In 1973, Bengt Ilon, Swedish inventor working for a company named Mecanum, AB, formulated an idea for a wheel which could move in any direction, thus the term "omni-wheel". Ilon's original concept was to attach a number of free-wheeling rollers, around a rim, with the rollers oriented at 45º with respect to the wheel’s axis of rotation. This feature would allow the wheel to move not only perpendicular to the axis of rotation, but also at any angle between +45º and -45º degrees.
This strange-looking wheel is also known as the "Ilon Wheel" or the "Mecanum Wheel". Non-continuous periphery of the omni wheel limits its uses to applications where slow speeds only are required.

Gear Motor 2 - 224:1 Offset Shaft :: Solarbotics. Hey - are you making a certain Most Useless Machine? We also have the wheel, motor mount, battery holder, and SPDT switch you'll need to build your project.
Solarbotics is the sole commercial outlet for these impressive 224:1 gearmotors. They are very comparable to a hobby servo for power, at a fraction of the cost! This motor offers 48.6 in*oz of torque at 3V, rotating 360 degrees every 1.5 seconds (24 rpm - just a hair slower than a servo), drawing 400mA at stall (free running at 40mA). With a 7mm double-flat output shaft (avoid using the "D" output - it's not meant to take rotational load), and a built-in clutch (limiting at 60 in*oz, but easily "locked"), and built-in mounting screw holes, you can see why we like these motors! These units have an overall size of 55mm (2.17") x 48mm (1.89") x 22.7mm (0.894") thick, while only weighing 31.4 grams or 1.11 ounces. Check out this quick tutorial for how to modify the GM2 from a torquey slow 224:1 ratio to a speedy 14:1 ratio.

Www.odd.org.nz. The OddBot is a little mecanum wheeled omnidirectional robot specifically designed to be 3D printable on almost any 3D printer, ranging from the Up! Printer to high end laser sintering systems. A mecanum wheel, invented by Swedish engineer Bengt Ilon in 1973, is a special wheel, with angled rollers around its periphery, that allows a vehicle to move sideways without needing to change the angle of it's wheels.
If the front wheel rotates in one direction and the rear wheel rotates in the opposite direction, you get a sideways motion. This particular incarnation of a baby mecanum wheeled robot was inspired by the work of John Chan (aka Madox) who first posted his work on the Up! Forum. This project is intended as an educational 'open-source' project in which users are welcome to download the files, build their own and modify it to suit their needs.

Al.I.S.E is an Aluminum, Infrared Scanning Entity; or just an old-school style crank arm hexapod :) This project was based on the mechanicals of the "Hexapod Monster" kit I built and reviewed back in 2008.
I scaled it up a little, and added 2 super torquey gear head DC motors I found at a surplus store in Minneapolis. Power comes from a 9.6v RC transmitter pack, along with a separate 9v for the BS2 microcontroller. Motor control is handled by a Solarbotics 1198 CMD driver board kit. I used pencil top erasers for her feet, and found that using scrap pieces of solid core cat5e cable came in really handy for sub-board inter-connects. Obstacle avoidance is fairly rudimentary at this point, as I am only using 1 IR sensor along with flanking IR LED's. It still seems to work fairly well though.
"Jamming" Robot Gripper Gets Official: Article Published in PNAS. Remember that compliant "jamming" end effector unveiled by Colin Angle (iRobot CEO) at TEDMED 2009? Even then, it was demonstrated picking up medication bottles, keys, and water bottles (a hand-held version was also demonstrated). Well, it just got a whole-lot more official with the publication of "Universal robotic gripper based on the jamming of granular material" in the Proceedings of the National Academy of Sciences (PNAS). The cool thing about this method of grasping is its relative simplicity: a rubber sack (balloon) filled with coffee grounds is pressed onto an object, it conforms to the object's natural contours, and the air is pumped out (a volume change less than 0.5%) to form a stable grasp-- no complex grasp planning required.
Be sure to check out the new video and photos! Update on Oct 28th, 2010: John Amend, co-author of the PNAS article, wrote in to share this updated video with voice-over.

Introduction to Solenoids / Basics of a Solenoid Two basic laws govern solenoids: Faraday's Law Ampere's Law Faraday's Law The voltage induced in a coil is proportional to the number of turns and rate of change of flux. The induced current flows in the direction that opposes the changing flux. Ampere's Law The magnetomotive force (mmf) around a closed loop is equal to net current enclosed by the loop. Types of Solenoids There are two main categories of solenoids: Rotary Linear Linear solenoids have applications in appliances, vending machines, door locks, coin changers, circuit breakers, pumps, medical apparatus, automotive transmissions and postal machines to name just a few.

Transductores y Sensores en la Automatización Industrial. Descargar Original Introducción a la automatización industrial En un sistema de manufactura flexible, es de vital importancia que los dispositivos que actúan como elementos integradores del mismo, ofrezcan un nivel de seguridad que permita garantizar el desarrollo completo del proceso en ejecución.
En industrias tales como las alimenticias, refresqueras, manufactureras, comerciales, extractivas, de igual forma en lugares como museos, bancos, entre otros. En este sentido, resulta favorable la inclusión de algunos sensores, en los manipuladores robot, que hacen parte del Sistema de Manufactura Flexible en el Centro de Automatización de Procesos CAP.
Como sabemos un sensor es un dispositivo capaz de detectar diferentes tipos de materiales, con el objetivo de mandar una señal y permitir que continue un proceso, o bien detectar un robo; dependiendo del caso que éste sea. ¿Qué es un Transductor? Un sensor es un transductor que se utiliza para medir una variable física de interés. Exactitud Precisión.

Sensores - Conceptos generales - Robots Argentina. Introducción Un robot es, por definición, una máquina capaz de interactuar con su entorno. Si es móvil, a menos que se mueva en un espacio absolutamente acotado y preparado para él, deberá ser capaz de adaptar sus movimientos y sus acciones de interacción en base a las características físicas de los ambientes con los que se encuentre y los objetos que hay en ellos. Para lograr esta capacidad de adaptación, lo primero que necesitan los robots es tener conocimiento del entorno. Esto es absolutamente clave. Para conocer el entorno, los seres vivos disponemos de un sistema sensorial. Para esto se utilizan diversos tipos de sensores (o captadores), con un rango de complejidad y sofisticación que varía desde algunos bastante simples a otros con altos niveles de sofisticación de hardware y más aún de complejidad de programación.
Detalles sobre los sensores para robots Magnitudes físicas que es necesario medir para que un robot tenga algún conocimiento del entorno: Fotoceldas o celdas fotovoltaicas. Sensores y Transductores para medir: Desplazamiento, Ángulo, Inclinación, Aceleración, Vibración, Fuerza, Par, Presión. Neumática e hidráulica.
