PWM Servo Position Feedback (Read Servo Position)
I'll be hacking a PWM servo to have positional feedback for ARC using an EZ-B v4. You can also perform the same functionality with an Arduino or IoTiny on EZ-Builder. I'm merely using a EZ-B v4 because I'd like to play with my EZ-Robot JD Humanoid during the hack as well
.
You can read the servo positions of a pwm servo using this hack. Adding an extra wire to the PWM servos by reading the potentiometer position allows you to know the position of the servo at all times by the ADC input of an EZB.
I will be using these two robot skills....
Reading positions with the 8 onboard EZ-Robot EZB v4 controller: https://synthiam.com/Support/Skills/Servo/PWM-Servo-Feedback-ADC?id=18047
Reading additional ADC positions from an arduino over I2C to the main controller: https://synthiam.com/Support/Skills/Servo/PWM-Servo-Feedback-i2c?id=18069
Something even more fantastical than that.. but the concept is the same. Yes you can get cheap servos for ehh...cheap.
Look forward to Friday’s hack. DJ has an idea for expanding ports. The more the better for what I’m thinking.
Looking forward to see whats on your mind...maybe you want to build a rig for yourself? I thought about this a while ago, but binned the idea because I figured that it might be too hard to build with all those cables and straps!!
