I'm building an automated Arduino crane where the base material is PVC pipes. The arm consists of the picking mechanism and other sensors, so the total arm might come to about 2-3 Kg (I haven't built it yet).

Can you please suggest to me an appropriate make/model of servo motor which I can purchase (preferably from India only)?

It really depends on where you are placing the servo, how much peak load & at what kind if distance from the servo.

These Corona servos are capable of lifting 2-3Kg at a distance of 2cm from the servo centre. (look at the torque entry on the specification sheet)

  • Thanks, I actually went ahead using a normal 10 RPM motor and stopped it when an object was detected. It is quite accurate Oct 23, 2015 at 1:48
