Only 30 Robot Arm Diy Cnc Shield Control Stepperо #cheap robot arm this is continue video for the cheap robot arm, just around $30 costly. on this video i show more detail how to control robot arm full fun. Our robotic arm has three stepper motors at 3 axes. stepper motor 1 > at the base of our arm to give it rotation; stepper motor 2 > the second joint after the base; stepper motor 3 > the third joint; servo motor > for the griper of the arm; and three potentiometers were used to control the positions of our motors.

Step 3: first motion tests. after completing the mechanical part of the robot i quickly assembled the electronics and connected only the cables of the 6 motors. the test results were very positive, the joints move well and in the pre established angles, i discovered a couple of easily solved problems. Just don't plug in your a4988 drivers in the wrong way! the stepper motor at the side with the y limit switch has to be plugged in to the terminal for the y stepper motor in your cnc shield. the same goes for the motor at the side of the x limit switch. (we're calling these x and y since its easier to deal with the cnc shield this way) connect. Step 4: put it together. the servo brackets will come with fasteners you can use to screw one to the base and secure the servo motors in the brackets. the c brackets come with bearings and fasteners as well. the servos i used came with thin white wheels the were easy to mount to the c brackets.

Rr1 has 6 (6 joints 1 for the gripper) degrees of freedom and is powered by stepper motors. it is fully closed loop, i.e. every joint has its own encoder and at any time we know the current angles of all joints. the important feature that distinguishes rr1 from other similar projects is that each joint has its own custom built 3d printed split ring planetary gear reducer. the robot consists. The robot has 4 degrees of freedom and it’s driven by 4 nema 17 stepper motors. additionally, it has a small servo motor for controlling the end effector or the robot gripper in this case. the brain of this scara robot is an arduino uno board which is paired with a cnc shield and four a4988 stepper drivers for controlling the stepper motors.
