Let's Make Robots!

Most Collected: Tip/walkthrough

(Yes it's an old picture, but) as you see, we have our tools ready to work on robots.   This is just a miscellany of sensors your robot can use from time to … Read more
This walkthrough explains the basics of soldering, really important thing to learn if we want our robots to be tough!
here's the best one i've found so far,it really helps a lot. http://www.curiousinventor.com/guides/How_To_Solder Read more
Reveals yet another cheap method of making PCB's at home.
Hi all, Yes you read the title right, I'm going to describe here the method I used to create the above PCB using an INKJET printer. Prerequisites: 1. Inkjet printer … Read more
Uses current generated on coils in stepper to act as an encoder
Pretty simple circuit I found, you may have to play with the resistor values to get the output to logic level depending on your steppper.It uses two voltage … Read more
Gives text output from your project
** walk through in progress ** IntroductionThese monochrome serial LCD text displays are apparently very popular and easy to use. But the official manual (pdf) … Read more
Have you ever programmed a microcontroller and after just a little change you made, the code - that was running completely fine last week - is not working … Read more
There are various different chips which are commonly used with the Picaxe chip. Here I attempt to explain what each one does, where it goes and why you might care. … Read more
Ever wanted to know if your battery has just the right voltage to run your robot. Sometimes I stick a battery in a robot and it just limps over. I figures that the … Read more
Give a sense of touch to a robot using light
I've been trying to think of a good sensor to mount onto my polypod's legs (Yes, I'm still working on it) to give them a sense of touch.  Some people have very … Read more
A basic - intermediate walkthrough on programming in Spin
This is part 1 of a multi-part series.  The other parts are here. The Parallax Propeller can be programmed C, Spin, or Assembly; I think most people use Spin.  I … Read more
Have you ever made a robot that ran fine when you held it, but when you put it on the floor it moved really slow (or not al all)? Hmm… Did you use a motor … Read more
Robot platform from Raspberry Pi and Arduino orchestration
This article is specific: How I personally would setup my Raspberry Pi to act as robot base.  But, I'll be clear, this is one of nth possible setups.  A … Read more

Guides you when doing the math inside the code.
The need to convert the result of the ADC pins proportionally to servo positions arose recently in my Pic-Aim project, which in turn was inspired by this comment. … Read more
Expands PWM outputs for servo control
     Those who intend to build a more complex project (in this case I mean with more DOFs, like a hexapod, biped humanoid and others) may find dificulties if … Read more
