Let's Make Robots!


What would you want on a Propeller Quickstart "do it all" shield?

After playing with the Propeller Quickstart, I'm thinking it could use a "shield" to make it more "Arduino" like.

Something like the Mega Sensor Shield, but with a few more goodies. I'm quite a newbie at electronics, so pardon my innocence..... ;-)


External Power Supplies

Eggbot may not go further

Here's the first hardware run on the next project-just a big cheap egg platform. I was hoping to make this my first Propeller robot but I'm not sure if this is worthy of such an elegant processor.  Think I'll get better traction and balance out of those little black ducks with more weight over the center?  Such small wheels-I don't know if encoders are an option, and that one side is going about half the other. Right now the steel castor in the back weighs more than the rest of the platform combined.  Gotta come up with a good battery solution too.

Is an Arduino Capable of Reading All Four Rover 5 Quadrature Encoders?

Note: Sorry this post is so long. I used bold text to indicate the main point of the post.

I didn't want to hijack Oddbot's Rover 5 threadso I'm starting this one here in the forum.

In replying to odong's question about the quadrature encoders I stated (among other things):

Several robotics contests at Propellerpowered Expo

Hey guys,

If you are in the NE Ohio area on August 17th, 2013, plan to visit the Propellerpowered Expo!

There will be all kinds of Propeller based projects, as well as three different prize winning Robotics contests.

Expo Homepage: http://www.propellerpowered.com/expo

Expo Thread with details: http://propellerpowered.com/forum/index.php?topic=483.0

If you are using the Parallax propeller, or just curious what all the fuss is about, this is a great event to attend.

Thanks for listening!

IRIS System - update 5

 I've been doing alot of work on the project latley, but not posting about it here very often. It's mostly coda and small stuff, but if you want to follow the progress or help in any way, go to my github page: https://github.com/ANTlabs/IRIS-System


 Be sure to view the wiki or readme first!

IRIS System - update 4

 I pretty much have the sound systems up and running, the speakers are working great with some minor audio distortion (but that's probably because when I tested it, I didn't have the capacitors in). The microphone on the other hand is having some issues. I'm using the circuit from the demo board and the microphone to headphones object, but the audio I get back is very grainy. To get anything at all, I have to be within an inch of the mic. (could be because I yanked it out of an old phone). But overall, I get some audio.


IRIS System - update 3

 Just a quick update on the ststus of IRIS. I got the wii nunchuck to work with my prop. fairly quickly using a connector from adifruit. I still can't seem to work out the prop. to picaxe serial, though. But the real news is, I've decided to put the code up on github so anyone can help to improve it and reuse the code. Here's the link: https://github.com/ANTlabs/IRIS-System

IRIS System - update 2

 I've worked on this alot latley. It's an improved version of my text editor. Basically, it was made to test the keyboard input and TV output for the propeller, but ended up being alot more work than it was worth. In the end, I just realized that I only needed to use the ending string (13, 10). Only some minor problems remain: no tv objects will work unless the prop. is plugged into the computer and no spaces show up when using the read method. Here's the code:

IRIS System - update 1


Horay! I just got my GG propeller board USB:

Variables and operators help in Spin

Hi again LMR Im having some problems writing basic obstacle avoidance code for a propeller based robot with a ping
when i compile the code i get the error "variable needs an operator"
its a bit noobish of me really but im a bit stuck.
And yes i have read the pages on operators in the propeller manual (page 144 in the propeller manual v1.1)
Heres a screen cap for those interested

many thanks for the help

RFID Keylock - RBBB Propeller

Continued......... Video explains the details ....including the painstaking job of finding the right house wires....ekkk

Removed the "Elfish PC" as its needed on another project.........

..... Replaced with a super cool RBBB Propeller board M44D40 found on the parallax forum, for 20 dollars.

I choose this board because of its size and simplicity (it has to fit inside my RFID box) .
