Hi, ive seen many threads without or asking on how to add humanoid walking. Its down to logic really. I have put together this simpel tutorial to give humanoid walking to your arduino bot.
As i do not have an arduino yet, i cannot supply source or pictures.
Parts list
4 servos
4 beams (metal, wood w.e)
Arduino
How?
Since a picture is worth a thousand words, follow this schematic:
Simply repeat this for leg 1.
Now that that is setup, connect up the servos to the arduino and begin programming.
Here is a simple way of movement:
SERVO 1 FORWARD (90 degree angle)
SERVO 2 FORWARD (45 degree angle)
SERVO 1 BACKWARD (45 degree angle)
That is simple and isnt tested, yet, if it doesnt work, simply take a look at your own walking and use it in your robot.
Hope this helps.
