I presented this project at the 28th Montréal Python meeting. I posted the slides of the presentation in my previous post here. The objective of this project was to demonstrate the use of  pyserial and XBee to wirelessly control a robot. This project was also my first attempt at using the Tweepy library. The requirements […]

Montreal Python #28

Today at 18:30h, I’ll make a short presentation at the 28th edition of the Montreal Python. I’ll present my PyGame Wireless Game Controller and a robot controller by the web. More details about the presentation on the Montreal Python Website: http://montrealpython.org/2012/03/montreal-python-28-lithographic-lobotomy/ You can get the slides of the presentation here: https://docs.google.com/presentation/d/1KTqljkl-fSZyuhXonCrQN10HsEFdp5AsavMEvj8bdRU/edit#slide=id.p

Controlling DC motors is at the heart of many robotic projects. Servo motors are sexy but DC motors are cheap and a lot more useful to control wheel based robots. In this article I’ll display a “robot shield” circuit that allows you to use cheap motors to drive your robot. Wiring This shield has been built on […]

This simple robot is using a L293 chip to control two DC motors. The motor gearbox and the tracks are from Tamiya kits. The proximity sensor is a small Maxbotix sonar. You can get the code of this project at https://github.com/pchretien/robot_01. I’ll soon post a new article showing how to add IR remote control to this […]
