Arthur Sacek: LEGO. Since I was at high school I have been building robots that play tic tac toe.
But this one is special... Servo Vs Motor PAP, ¿cuál es más preciso? Cuando hablamos de precision que mejor por optar por motores paso a paso ten en cuenta que los motores paso a paso son exactos si de precision hablamos, ademas que no sufren desgaste alguno porque el movimiento es producido por campos electromagneticos producidos por los enbobinados, no muy facil de controlar, pero puedes controlar y crear micropasos en lugar de pasos normales.
Un servomotor es muy facil de controlar debido a que solo tenemos 3 cables 1 positivo 1 negativo 1 de señal al inyectarle un ancho de pulso especifico al servo podemos tener control, todo el control esta con respecto al ancho de pulso que se le asigne. No son muy precisos ablando exclusivamente de los analogicos, existen servos digitales son con mayor precision pero son demaciado costosos. PyroElectro News, Projects & Tutorials. Tutorials. I can program a robotic car - AI Matt. It’s official.
I now know how to program a robotic car. It was not easy by any means, but I aced Udacity’s seven-week class, CS373: Programming a Robotic Car. I spent a few hours a week on homework and a few hours a week on classwork, with the seventh week being the final exam. I had to brush up on some math concepts I started to forget, like matrix arithmetic and probabilities, but I was able to get through, thanks to the Khan Academy.
Custom Quadcopter Control Board - AI Matt. After seeing hobbyist-oriented batch PCB services, such as Sparkfun’s BatchPCB and Laen’s OSHPark, I decided instead of squeezing an Arduino Mega and a DFRobotics shield into a plastic food container, I would make my own, compact PCB and send it out to be manufactured.
To my dismay, it all worked on the first try! Step 1: Establish requirements There are some measures to cut cost and complexity (and thus board size) that were taken due to the nature of a multirotor. First, we can get rid of the voltage regulator circuit, since we will be powering the board with a 5v BEC such as this one or powered by an ESC motor controller with a BEC built in. This allows us to remove a voltage regulator and two electrolytic capacitors. I also left out the FTDI USB serial converter. Step 2: Get it working on the breadboard I’ve done breadboard Ardunio projects a bunch of times, so I’m pretty familiar with the process. Next, I needed to map out the pins. UAV and Model Airplane Design, Building and Flying. Final Proposal – “Scout” Scout For my final mechanisms project I would like to build a twin tilt-rotor remote controlled helicopter.
I am calling it “Scout”. I found that most types of remote control helicopters are very hard to fly for beginners. Current R/C helicopter design come in two style coaxial rotors and single rotor with a tail rotor. The coaxial rotors offer very stable flight but are not agile. Horizon Hobby. RCTimer/Turnigy/Hobbywing ESC DIY Firmware Flashing. Thanks to the help of timecop (yes he can be nice as long as he is interested ) I managed to flash my RCTimer 10A and 30A ESC.
The procedure should be the exact same for the 18A and 20A versions. DIY Drones. Skill Set: Intro to Machines and Mechanisms. This month, for our Mechanics Skill Set, we’re happy to have our friend Dustyn Roberts joining us again to help out with the theme.
We’ll be excerpting from Dustyn’s book, Making Things Move: DIY Mechanisms for Inventors, Hobbyists, and Artists, doing a giveaway of signed copies of her book, and she’ll be writing some original content for us. Today, we thought we’d kick things off with a chapter from Making Things Move, Chapter 1: Introduction to Machines and Mechanisms. ArduTiger, un robot qui évite les obstacles - Brico bidules. Parts List. Last Updated on January 28, 2014 The “Parts List” is organized with the quantity and recommend part first e.g.
(Quantity) Part Name. GRASP Laboratory - University Of Pennsylvania. The Autonomous Aerial Vehicles rresearch project is mainly focused around autonomous navigation of unmanned air vehicles.
The challenge is to design systems, which exhibit a goal-driven behavior, while sensing and reacting to changing environment. This project is a collaboration between students and faculty from University of Pennsylvania and industry experts from Dragonfly Pictures, Inc. The GRASP Laboratory at the University of Pennsylvania is proud to be operating a Research Experience for Undergraduates (REU) Site entitled Perception, Planning, Mobility, and Interaction for Next Generation Robotics.
This REU Site opened in 2012 and is funded by the National Science Foundation (NSF). Please see the GRASP REU Site's website for all details on this program. DIY Drones. Arducopter - Arduino-based autopilot for mulitrotor craft, from quadcopters to traditional helis. The DIY Drones development team is proud to bring you the ultimate open source quadcopter and helicopter UAV!
ArduCopter's autopilot is based on APM 2, the most sophisticated IMU-based open source autopilot on the market. It provides full UAV functionality, with scripted waypoints, Ground Station and more. Advanced GCS Waypoints! See the Wiki manual linked above for full details and instructions. Sample video: GPS position and altitude hold See some other ArduCopter videos here!
