Project Summary

In a manufacturing environment there are many areas that could benefit from the automatic loading and unloading of finished goods from machines by robotic arms. One example is the unloading of milled parts from a CNC machine. Another example is the movement of parts from the outfeed of a large sanding machine back to the infeed area. It is important to note that at times these machines may sit unused for one or two weeks. Because of this, if each machine had a designated robotic arm for loading and or unloading they too would sit unused. A way to avoid a robotic system from sitting dormant while its assigned machine is not in use is to have one portable robotic arm that could be pre-programed to load and or unload from multiple machines. The user of this arm would simply need to place the arm next to a machine and start the program for that machine. Next to each machine there should be a marked area that will outline the docking position for the robot. Note, the body of the robot itself may need to be mechanically fastened to the ground for secure and exact placement.

For this senior design project, the main objective will be to develop and build a SCARA robotic arm controller and arm for the CNC unloading situation referenced above. This arm will be used to unload a CNC table after the cutting of parts is completed. When a CNC has finished cutting wooden pieces out of a 4’ by 8’ sheet of plywood the location of the pieces will be sent to the controller application on the PC which will direct that to the robot’s controller.

Unlike other controllers in the robotics industry, the background calculations behind the motion for a robot will be done on a desktop application rather than within the internal firmware of the controller. We will be investigating using Autodesk Fusion 360 as this PC application.

The focus of this project is to build a robotic arm and respective controller along with a PC application to achieve the unloading of a CNC table for multiple machines and programs.
