## Arthur Sacek: LEGO | Tic Tac Toe | 2004

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.

## 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.

## Week 11 | Final Proposal – “Scout” | World of Russ

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.

## 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.

## MAKE | Skill Set: Intro to Machines and Mechanisms

L'idée m'est venue suite à l'amélioration d'un char radio-commandé qui m'avait laissé sur les bras un châssis à chenilles avec ses deux moteurs et après avoir découvert l'Arduino sur le web. Le châssis de char lui donne un petit air guerrier mais, pour citer Doc Brown, quitte à faire un robot autant qu'il ait de la gueule. Le concept est classique : le robot avance et un détecteur mesure la distance aux obstacles situés devant. En dessous d'un certain seuil, il effectue une manoeuvre d'évitement.

## Current Projects | 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

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.

## R/C Hobby Store :

Paintball Robot Overview I want to make a tracked robot with a paintball gun. The robot and gun will be controllable from a distance. The gun will have elevation- the ability to tilt up and down.
