Let's Make Robots!

The case for lurking on LMR before starting on a large (ish?) robotics venture...

Ok... so let me start with... I've been humbled by the sheer simplicity with which some of these bots on here are made.  Functional and clean.

 

The one article that has made me rethink my strategy the most is  Oddbot's article Pushing the limits with encoders  

 

Why is everyone here so good looking?

Not just Kariloy.  I mean, I'm just sayin-this has got to be the most attractive group of robot makers in the world.

Homemade compound eye

The compound eye from DAGU, designed by Oddbot, is cool and cheap. But I needed a round board to imitate the human eye, so I made one by myself. The IR LED's and photo transistors are the same as in the original design. As I had no PN 100 transistor, I used a BD 139 (the 4 IR LED's draw approx. 100 mA @ 5 V).

Hi all,

For some time I've been playing with IR sensors, trying to get some "eyes" for my little bot here:  http://letsmakerobots.com/node/19894

It is based on the IR Compond Eye design from Oddbot only smaller because I want to use two of them on the bot to get a very approximative distance measurement. 

Here is a version much alike Oddbot's but with only one phototransistor and 4 IR leds, and a 10K resistor instead of 4K7 to get a little better sensitivity from the transistor :

A few things have happened this last month. I meet Xiao Yue (Little Moon) about a month before I went to Australia. She can't speak much English and my Chinese is still very bad but she seems to like me anyway.

This was taken on her birthday. There was a bit of a food fight with the cake so we ended up with cream on our faces.

OddBot, Claudia, DAGU... they just rock...

Jeez, i ordered from DAGU 20 mini servos one week ago... and i already received them! That's even faster than most of the sellers in my own country!

So thanks to them, and thanks to OddBot who took the time to think about my special needs and perfectly fulfilled them, saving me a lot of time (and money!)

Here on LMR we are really lucky to have them all... :D
