New tutorial on how to make an Arduino robot

I posted this on the Facebook page, but thought I'd post it here as well.

I just finished writing an in-depth tutorial on how to make an Arduino-based robot. It's targeted towards beginners and should help someone completely new to robotics to build their first robot, but anyone making a robot with an Arduino will find it useful. Here's picture of the robot I make in the tutorial:

PID Tutorials for Line Following

Hey there guys. This post is outdated. Visit http://letsmakerobots.com/node/39972 for the updated tutorial.

Hello LMRians,

In this writeup, I will try to create a tutorial for tuning your robot using PID to follow a line. This tutorial won't go deep down into the details of PID and its applications but will just attempt to show how a robot can be tuned with the PID parameters to follow a line.

Cant find a tutorial !

Hi everyone,

Recently I came across some very good hexapods designed with 6,8 and even 12 servos.I have a duemilanove and would like to build one.

But unfortunately I have not ventured into this domain and my search for a step by step tutorial on google(on multilegged critters like hexapod) and instructables proved futile.Any Links that can help me get started or rather a complete tutorial link would be awesome.Thanks!

Pic simulation and debugging

I've had a university assigment using a pic and had a bit of a trouble to find an easy way to program and simulate for the 16F628A.

So I made this small video tutorial using Mikrobasic, Proteus and MPLAB.

High Speed Photography Help!

Hello everyone!

this is my first post so im pretty excited haha.

i want to know how to create something so i can shoot high speed photography.

an example of what i would like to do is of a water droplet hitting a bowl of water and snapping a picture when the "crown" (part of the water which gets drawn up from the result of disrupting the water bowl".

i was thinking about a laser activated "flash" which fires the flash of the camera after the beam is broken, but it should have a delay so i can fine tune it and get the perfect image.

Thinking of XBee Communication, a few questions before I jump in

What I intend to do is create a wireless link between my robot and my laptop, for remote serial programming, and remote control.

I posess a PICAXE 28X1 project board that i wish to connect with an XBee module.

From what I've seen in http://www.rev-ed.co.uk/docs/axe210.pdf an AXE210 is suggested. On page 9 however, we find that the XBee is only connected to the AXE by three pins: two inputs and one output.

LV-MaxSonar Sensor Questions

Hello,

This is my first post here at LMR. I decided to write out a question in the format of a blog. Since I've had some trouble getting my head around this issue and I found limited resources regarding this special device on the Internet. Creating a blog post might help other people with similar questions as me. 

UPDATE: I decided to remove the H-Bridge part, now the motors are directly connected to the AA batteries, and the Arduino is connected to the 9V battery. This … Read more
