Propeller Boards to use in Robots

As many of you are aware, I'm a big fan of the Propeller. I frequently get asked various Propeller related questions in the Shout Box which I'm all too happy to answer. However, I thought it might be a good idea if I made a more permanent record of my Propeller board related suggestions.

Navigate under remote control or automomously.
Prompted by Bajdi's and Mikronaut's hexapod builds, I decided to purchase one of the many inexpensive hexapod kits. Apparently I was one of the fortunate ones and … Read more

Eavesdropping On Adafuit's FONA

I recently purchased one of Adafuit's FONA modules.

Adafruit FONA - Mini Cellular GSM Breakout - SMA Version - v1

 

By following Adafruit's tutorial, I was able to use a serial terminal to send text messages. The tutorial didn't include an example of reading a text message and my attempt to decipher the datasheet ended with a bunch of error messages.

3-Axis Joystick with Button

Edit: Here's link to the Aliexpress seller I purchased the joystick from.

I saw this joystick in a Hackaday article and I thought it looked cool. I really liked that it had a knob on the joystick.

Wii Nunchuck Control Scheme

Edit: I don't expect many of you to read though this blog. This ended up being a way to "think out loud". It helped to write these ideas down.

It's probably not a great idea, but I'm using a wireless Wii Nunchuck as the remote on my hexapod.

On start up the hexapod uses the joystick as direction control with rotation control performed by pressing the "Z" button and rotating the Nunchuck to one side or the other.

I'm trying to come up with a way of having the input from the Nunchuck able to control different aspects of the robot.

Overall Structure of My Hexapod Program

I've been trying to add additional features to my hexapod code for several weeks now. As I mentioned in my last blog, I've spent some of this time freeing up RAM. While I've made a little progress towards adding some the features I desire, I haven't made nearly as much progress as I had hoped. I'm hoping my fellow LRMians won't begrudge my effort to get my taughts straight in my brain my posting them as blogs.

Making Room In the Propeller RAM for More Features

This is another "thinking out loud" blog. A couple of weeks ago I mentioned to Gareth I was down to 798 free (32-bit) longs. Since I knew I wanted to add additional features, I needed to figure out a way of freeing up some RAM.

Mounting Wheels to Servos

In an attempt to answer a question about using wheels with CR servos, I'm moving the following post from the Mr. General thread.

Im sorry for my english. It's very poor. I used google translator to translate some sentences:(

Anyway, I ask about servos, because i want to use one of this wheels to make robot based on this project:

So far it's used to test modified Eddie firmware.
As I mentioned in an earlier blog, I was given a bunch of really cool robot parts by Parallax in exchange for modifying their "Eddie" code to work with different … Read more
