However, you may decide to add more servos as the build progresses. You could change the design of the arm to give it two or three degrees of freedom (DOF), or you might add other attachments such as a gripper claw, a sample return arm, or a laser turret. Whether you keep the rover simple, with just a robotic arm, or you add to its capabilities, you’ll need to be able to control those servos smoothly and effortlessly.


At its core, a servo (or servomotor ...
