Hi all,

First post.. first robot. :-)

 

The Propellers Spin code has some very neat OBJ routines to work with complex maths. This is a run down on how to use the floating point routines. Since starting … Read more

How to turn my netbook into a robot "brain"

So I've had some experience with an Arduino and a BOEBot, and was thinking of taking another step forward.

Why is portc high = low?

Using Picaxe "portc", I can get 16 outputs from a picaxe 28, which is neat.

But I allways wondered why you have to write "high portc 5" to get "portc 5" to be "low"??

I understand that since it on default is an input-port, it must be set on "high" on power up. But still you should set it to "low" by writing "low portc 5", and not "high portc 5"?

Gets quite confusing sometimes in my code; half of the outs has to be set low to be high!?!?!

Rocket Brand Studios/ CtC Update

Hey guys,

It has been a whirlwind around here for quite a while... Ever since Maker, it has been non-stop (and wonderfully exhausting).

I thought I would take a quick moment to record a video and let you guys in on the chaos and upcoming goodness.

Flea Market Find, Crawler Bot

Found this RC rock crawler missing battery cover and remote at our local flea market. For only $2 thought it would be a good start for a bot. Will use the arduino that I already have for this I think.

Disassembly was straight forward, 4 screws on truck shell 8 screws on board cover and all is exposed.

self balancing bot

check this Self-balancing robot on instructables. It doesn't stand upright for very long, but it's a very good starting point, IMHO.
