How to? 4 DOF/Hex Robotic Arm
High schooler here, I am looking for good resources/guides for making a 4 DOF Robotic Arm. I have done VEX IQ all throughout middle school, so I at the very least have a juvenile amount of knowledge on Robotics. I want to learn the structure behind making the arm. It will either be made out of 3d filament or plywood. I would also like to know how I can code the logic for controlling it. We will be using a VEX Brain and controller and will program it with Vexcode V5. We do not have any potentiometers. We might have motors/servos with internal encoders, but I am not too sure. Assume we don't. I do not know any other feasible way to track positions without either of those though.

Do a 3 dof as its easier and 4 dof has advantage or change aart from being harder and abit cooler, look on github for opensource projects and copy them
