Still alive, power problems

I'm not dead, I just had a little foul up with my Baby Orangutan and never got around to ordering a new one.

Update! This is Phoenix Revision 2. I got tired of the round base plate so I decided to rebuild the whole thing on a solderless perfboard. This is another temporary … Read more

Back from hiatus

Hello all,

I have returned back from my robot building hiatus.  I've been saving up my money to buy these two things:

Now that I am sufficiently poor, it is back to robots :D.

I have two new ideas and a derivative I am working on.  Ta ta for now

Hi LMR, This is my latest walking robot under construction. It's an improvement over my Lollypod robot in that it uses three servos per leg rather than two. This … Read more

My Computer Found it's BellyButton

Yeah, it doesn't look like much... but I'm excited.  I've been meaning to do this a while, just didn't have the time.  I'll be doing a variety of tests to see how it preforms.  It has several "Match" algorithms to play with (CV_TM_CCOEFF_NORMED, CV_TM_SQDIFF, etc) - and I think there are several normalization routines.

This match algorithm seems fairly fast @ 120 ms - Haar Face Detection takes longer...

This is my first robot that I made with an Arduino. It's made of two pieces of plexiglas. The upper piece stands on 3 threaded rods. The motors are attached with … Read more

My First Bot missing a cable for the Sharp IR sensor

I found what I think is a matching cable on DFrobots under Arduino sensor parts as a Cable for Arduino Analog Sensors. It looks like the right cable. It is 3 pins with a JST type connector. It is the best fit I can find since Solarbotics no longer ships the IR Sharp Cable with the unit. DFrobots sells the same IR sensor with the cable and that cable matches the Arduino Analog Sensor Cable and the Sharp part number as “JST -3 Sharp” for the cable.

Note: You can follow some projects some of the time, but you cannot follow all the projects all the time.

Biped Howto: Moving servos

+++ UPDATE (12-march-2014): Rename title as "Biped Howto".

Hi, I will try to explain, in a very simplistic manner, the way in which servo motors can be controlled.

Servo motors are controlled by a PWM signal, in which the active part of the signal (known as duty cycle) define the amount of degrees the servo will rotate.
