We designed and built a robotic arm that follows the SCARA topology. The intended use is to input G code into the python script and have the arm recreate the image using its parsing function to read the G code file, the python script will then read the various G commands and based on the command, change the movement, speed, height, and tool of the arm. The servo motor at the end of the arm controls the tool that is currently in use. The two limbs of the arms are moved using stepper motors. Similarly, the Z axis is also controlled by a stepper motor. One unique feature of our arm, is that the entire base of the arm rotates as a whole, and although our group thought there would be a lack of torque in the arm to rotate, but by providing around 24- 36V we have more than enough force for all three motors to work. One place our arm succeeded was in the speed, and tool changing abilities. These were absolute strong suites of our arm, but our arm failed in the accuracy of its drawing. We were not able to get a 10 inch straight line. We were close, but just shy of this requirement. In the future, we would like to make the arm lighter, more accurate, and less shaky with more sturdy parts, more reliable code, and more heat sinks to cool the motors more consistently.
