I have designed something where I need two micro servos mimicking each others movement. a micro servo (servo 1) copying the movement through a wireless connection when user MANUALLY turns servo 2. User will either manually rotate servo 1 or 2 by hand then the other servo through a wireless connection will copy the rotation or movement of the manual operated servo. (Please I’m NOT needing servos being controlled by a wireless controller operating both servos simultaneous wirelessly.) Servos must work when user manually turns one servo the other servo copies the movement. Servos must disconnect from battery once movements have been established to save battery life.
Think of it like the doors on a car. If you manually insert the key and turn key to unlock the drivers door it will unlock drivers door only but if you manually turn the key twice then all the car doors will unlock.
The servos to be powered by a 9v, two AAA or two AA batteries.
Servos will NOT be hardwired together rather using a wireless connection between them.
Once the servos have finished the movements servos will need to disconnect from battery to save battery life.
Servo one will be operated manually by user then servo two will copy through a wireless connection servo one’s movement. If user manually operates servo two then servo one will copy the movement through a wireless connection and servo one will copy servo two’s movement.
You can probably use Analog Feedback Micro Servos.
One servo’s feedback would be connected in analog input to an Arduino board+XBee Shield.
The XBee module from the first Arduino+XBee Shield will wirelessly send commands to another XBee module on a second Arduino+XBee shield to control the second servo.
This way, the second servo will rotate depending on the first servo position.
You might also use Smart Servos.
Can it all run on a 9v/AA or AAA battery (or other small power source), because it needs to be mobile?
Will Purchasing 2 full sets (arduino boards, Maxstream Transceivers, and micro servos) enable set 1 to be manually rotated left and right then set 2 respond simultaneously copying the left or right movement?
Do you know whether this is the smallest, most efficient solution available?
You can probably run each set of Arduino+XBee+Servo with 9V battery using this battery case.
You still have to program the two Arduino boards with the behavior you described. You might find examples online.
Another suggestion, might be the use of a 2 sets of a Wireless Servo Controller + Arduino Nano and a 2.4G Transceiver nRF24L01P+ Module (2pk), 9v battery holder.
1st Analog Feedback Servo will be controlled manually sending its position to the first Arduino Nano+Servo Controller.
The Arduino Nano will communicate with the 2nd Arduino Nano trough the 2RF24L01P modules controlling the 2nd Analog Feedback Servo via the 2nd Servo controller.
Both sets will be powered via 9V battery each through the screw terminal on the Servo Controller.
