Mars Rovers and you

Recently, I posted blog comparing the computers used for the Apollo moon missions to an Arduino.  The Apollo Guidance Computer (AGC) was considerably less powerful than an Arduino.  Continuing along that line, I started investigating other computers used for space exploration.  Since the mars rovers are popular among robot builders, and often the source of inspiration and goals, I decided to take a look at those.  The results are rather interesting.

Emotions and Motivations as behaviour architecture

Hi all, a few days ago, I started designing the behaviour-based architecture for my robot Hurby. I thought to design it as a Subsumption architecture (see my previous blogs) in which different behaviours compete to be selected as dominant, and hence move Hurby accordingly.

Robot Class

I am in the process of submitting a course proposal for an adult evening education program that would introduce people to robotics. One of the entries that I must fill in deals with expected material costs. I would appreciate feedback on what would be appropiate expenses and whether the school should include the costs as part of the registration or if the student should buy the components as needed. I am in favor of having an option not to build.

On a similar note, would it be better to first offer a course in "C" programming geared to a possible robotics controller board?

Extra Hardware Needed for Larger Hexapod

About a month ago I purchased hexapod kit off ebay.

Yesterday as a break from program my Mini Hexapod, I started putting together this larger one.

quad encoder read speed

This is as much a programming problem as it is a mechanical issue I guess.
A few of us are working with quad encoders at the moment and I'm just wondering about ideas how to overcome a problem I've encountered using some.
I'm using interrupt on change to count encoder ticks and also reading a 16 bit timer for the interval between ticks on each motor.

Use an Arduino to get to the Moon

So, this whole Maker movement has got you excited, and the rocket you are building in your backyard is nearing completion.  But you haven't decided on a navigation computer yet.  You were thinking of using a laptop, but your daughter needs it for school.  Maybe a Beaglebone Black.  Darn!  Seems they are sold out everywhere.  You look around your lab, but all you can find is an Arduino. At first you pass right over it.  But when you can't find anything else, you start to wonder, "Could it get me to the moon?"

ComMotion Shield for omni and mecanum wheel robots

After building my first omni wheel robot I realized how difficult it can be to monitor 4 encoders and drive 4 motors so I designed the ComMotion shield. As the name suggest the shield is designed for motion control but as I ended up with 2 spare serial ports I decided to add communications abilities to the shield hence the name ComMotion.
