i'm a beginner here and also in robotic world. please kindly guide me, what kind of sensor i have to add and where should i put those sensors on each joint?
i mean, i want to "teach" the arm like this short video on this teaching arm video on youtube. basically, i have 6 digital servo which is told they can return the value of the angle position, something like 4096 or 360/4096. i'm not sure about this. perhaps if i give a command such:
it will go to certain angle of 360/4096.
but that's from coding/programming side.
what i want to know is, i want to move the arm by my hand, so i will record the angle position of those 6 servo.
i think servo1.read only read the last value. so if i move the arm by my hand, i really don't have any idea what to do with arduino or what command should i use or what sensor should i use, to capture the recent/current value of the angle position.
i've googling alot, it seems easy but not for me. ::) i've searching through youtube but i don't have any idea if they put any additional sensor on each joint so arduino can read the current angle position.
please kindly give me a direction. any other sensor should i put on each joint? or simply just query the servo? thx in advance :)
