Servos or Stepper Motor. 28byj-48 Stepper Motor Stepper motors are commonly used in our daily used materials like they are in CD-ROMS in AC cooling units turntables and so many other things They can have 4 or more than 4 coils but basically 4 coils in unipolar arrangement and each coil rated with 5 volts. The same goes for the motor at the side of the X limit switch.
The base is made of plywood and its role is to hold the arm and contain all electronics. The first arm motor This raises and lowers the base of the arm. Fasten the horn with M2 bolts of 8mm length.
Rather than write a bunch of stepper motor. The only downside is the loss in speed. The actuation of the arm elements is performed by three stepper motors while the torque is transferred by 08mm steel cables through Bowden tubes.

It improves not only the precision degreesstep getting smaller but also increases the output torque. If you need 1-12 foot-lb of torque you will need larger motors or use counterbalances or countersprings on the arms to help reduce the required torque. My thinking is that I can use this to set an upper limit on the weight of each joint then see the torque values and find the motors that will be under-weight and over-torque.
Project tutorial by Eben Kouao. The NEMA-17 and the A4988 Driver si used to control the direction of the Motor you can see from the diagram below. Robotic Arm Stepper Motor and Driver A Stepper Motor NEMA-17 can be used due to its precision and high torque helping the Robotic Arm rotate seamlessly to gesture controls.
So if you are designing a robot arm that will need to move heavy loads the added torque of large stepper motors versus the torque delivered by servos will allow your robot arm to lift and move much heavier objects. The fact that theres a 164 gear built into housing is huge. Place the servo horn on link 1 servo and fasten it using m3 bolt provided with the servo.
