Hello friends,
I am trying to make a haptic glove interfaced with robotic arm with the simplest form i.e. robotic arm will consist of just two bars driven by two servo motors mimicking the action of corresponding two fingers attached to two more servos to provide feedback.
I think I can use the basic circuitry of controlling servo motor using potentiometer to control servos on robotic arm. I was wondering if I can use the internal potentiometer of servo to do the same?
How can I design the feedback circuitry to servos on fingers?
(An idea I had was using some sensor to detect an object in robot's arm which when activated will send a pulse to servos on fingers to hold the current position.)
Thanks Richard.
However what I meant by modifying was that soldering a wire to the output of the internal pot and providing that output to the corresponding servo on robotics arm.
I think that would be pretty easy isn't it?
Can you ask a more specific question? I can think of a dozen answers, but only one of them is likely the one you seek.
Let us consider the earlier circuit with an added feature of a pot being mounted on robotic arm. There's a sensor which detects if there's an object in robot's hand. If there is then it gives a signal to enable the reading from the pot to the corresponding servo on user's finger. Thus the servo on finger holds its position.
So any idea on how I can design the circuit? However another problem is I would want the servo on finger to be able to move outwards but not inwards when the hold signal is given. How can I make that happen?
