but i learnt stepper motors are very useful to make movements in steps and angular mavements..... what about that...silverscorpionServo is obviously better to use in robotic arms because servos have internal control mechanism. So servos can give better control and precision than steppers.

yes i agree, servo's can pull heavy loads better than stepper..ash20kg? Servos would work better with those types of loads. But, they are more expensive.
If I were you I'd get one a piece and do some testing 😀

Yep, both are accurate. However, you'll have better control with servos in some cases as they have feedback control. For steppers, you will have to assume the motor will perform with the given command. In most cases they do, but if an external factor effects the torque or angle of the stepper like a bump, then you would not get the position you require.ice111Hi,
In robotic arm, pulling heavy load will not be the only issue, it should be also precise and accurate movements also on X, Y and Z axis.
The <a href="https://www.makemyhobby.com" target="_blank" rel="nofollow noopener noreferrer">Aquarium FISH & PLANTS online, shipping all India.</a> people assured me that they can able to provide 17-20kg servo torque for under $75 on special order. But just for trial and error that amount is also out of reach.
So looking for precise solution either go for Servo or Stepper or make a U turn and use pneumatic, but again that will be difficult to get in India for cheap.
