arm, that motor could just as easily be used to open the door of a smart
home, draw a picture, or help a robotic dog navigate a search-and-rescue
operation. The possibilities are endless.
TAKING A CLOSER LOOK AT OUR ACTUATOR
Though we can use all kinds of fun actuators to design robotic arms, for
smaller desktop robotic arms, one of the most common is what we call
a servo motor. These small electric motors are ideal for building desktop
robotic arms. When it comes to building robots, there are certainly more
powerful and accurate motors out there, but with their low cost, high
strength, and ease of use, ...
