Team Stealth Squad:


Our team created a dual-jointed robotic arm that would hold a pencil and draw a circle within a square within another circle. To do this we used a variety of Lynxmotion parts from the Engineering Lab classroom. The arm is attached to a surface using a c-clamp and is moved using two servo motors. The motors are controlled through a circuit board run with Matlab code. After calibrating the motors we went about creating an arm using aluminum tubes, servo brackets, and hubs. We initially used long (4"-6")tubes for the "upper arm" segment of our robotic arm, however this caused poor distibution of mass and led to an unbalanced and shaky product. Our final construct used 2" tubes for both segments of our robotic arm. After constructing the arm our team began to work on making a SolidWorks Model and creating Matlab commands that would control the arm and run the functions which we wanted with appropriate scale, speed, and accuracy.

Robot Arm

  • Our SolidWorks model shows the basic design and assembly of our robotic arm.
  • Fastners, pencil, and c-clamp are not included.
  • The SolidWorks file was created after completion of the physical arm.
  • It is thus more of a model/simulation than a design aid.
