Let's Make Robots!

Robot and Frank

Here's a quirky looking movie called Robot and Frank. Four clips at the link.

And here's another for a different style of robot movie. Archetype

They are like chalk and cheese but both look interesting.

How to delete comments

I keep posting replies to the top of the topic instead of after the question. I can't see a way to delete the mistaken post only edit it. Is there any way around this to change the position of the post?

Sonar

Ok I've never played around with these sonar rangefinders all you guys have. This isn't so much a question of how do you use them but I'm curious to know what is the difference between them and the sonar used in boats and subs?

Serial motor controllers

I bought a couple of these a while ago and just got around to playing with them and I found something odd in their command features.

DMC-1

I thought I'd check a few other controllers available from sparkfun and others to see if they also worked the same. What I'm talking about is the fact you can update only one motor at a time.

Arduino and ethershield

I have the ethernet shield with an enc28j60 chip. I used the web_server_switch .pde from nuelectronics and followed instructions there and elsewhere on how to get it working.

The problem is I can get it working in a local browser but I cannot access it from my galaxy. I turned on port forwarding for the shield and have checked everything on my routers settings but no success. I am running win7 with a netgear router. Can any networking gurus suggest some things to check?

PzKw "Tammy"

Start me notI decided to do this Tamiya tankbot as a blog as there's been a few similar posts lately and It is probably one of the most common platforms about the net so I will see if I can do something different with it. But for starters I have built it like a start here robot although I will not call it that.
At the moment it is controlled by a pic16F690 but I intend to build different configurations using other micros as well.

Cool video now and then

Clever add. I love those old tin robots.

slowing a shutdown in a circuit from instant to a few seconds
I thought I'd do this as a tip after Geir Andersen posted on the circuit redesign for his UAV. The need was to maintain a supply long enough on shutdown to flush … Read more
Finally broken my robot post virginity. I decided to get an arduino to see what it was all about and was surprised how much quicker you can do things with the high … Read more
