MundoHobby Ideation Systems | Bringing ideas to life Animatronicshop.com | Learning can be fun 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. OddBot Assembly Instructions Mechanical assembly Step 1: 3D print all the components. Step 2: Insert the ball bearings into the wheel hubs.
TennisRobot.org | UW Tennis Ball Collecting Robot 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
Ann P. Smith's Robots. "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. The latest effort is a joint effort between U.
Robots: Al.I.S.E Here is my latest robot. 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. Solenoids Basics 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. Rotary solenoids have applications in machine tools, lasers, photo processing, media storage, medical apparatus, sorters, fire door closures, and postal machines, also just to name a few. Eight Essential Application Considerations when designing a solenoid into your assembly Force – applies to linear products.
