Portland Community College | Portland, Oregon

Requires completion of lab-based homework, using PCC's lab equipment, outside of scheduled class sessions. Students should plan for approximately 2 hours per week on average and will be able to reserve time during open lab hours. The hours that lab will be available for this purpose will be visible for students in schedule notes and/or through other effective means at registration time.

Upon completion of the course students should be able to:

• Follow guidelines for robotic safety. 
• Describe barriers, sensors, and overload protection used in robotics safety.
• Use appropriate terminology to describe typical robot types used in local industries, their components, joint and end-effector types, control systems, and power mechanisms.
• Explain the methods for robotic motion control, as well as different programming methods, languages, and types.
• Perform robotic position teaching.

The course will include instructor delivered lectures and demonstrations stressing key topics in the course. In preparation for the lecture portion of the course, students will be expected to complete all reading and homework assignments. Students will examine, operate, and teach positioning of industrial robots in class. 

Students may be required to come to the lab after school to work in groups on equipment as a part of homework.

Assessment of student performance in this course will be in the form of written and/or practice-based questions. Some formal reports and presentations may also be required.

1.0 Wafer Transfer System Alignment
1.1 Understand the degrees of freedom a rigid body can have in 3 dimensional space, i.e. displacement freedom along x, y, z axis and rotation around x, y, z axis. Understand the alternative polar coordinate system of r, theta, and height.
1.2 Be able to read and understand conceptually a typical alignment procedure between two components of the material transfer system—the sender and the receiver (example: transfer of material from indexer to the shuttle arm) following the methodology below:
Step1: Identify degrees of freedom the system has.
Step2: Identify in which degrees of freedom, adjustment is necessary.
Step3: Identify what mechanism the equipment uses to adjust alignment in each degree of freedom.
Step4: Find out the order of alignment—which degree of freedom of the system needs to be aligned first, second, …etc.
1.3 Upon reading an alignment procedure, be able to organize individual steps into groups to better organize and understand the steps of the procedures. (i.e. step 1-4 may all describe adjustment of height and leveling)
1.4 By reading schematics and by observing the operations of an actual piece of equipment, be able to develop an alignment procedure for the equipment following the methodology above.
1.5 Be able to perform alignment procedures described in a manual.
1.6 While performing the alignment procedure, be able to use observation of relevant indicators as a feed-back to judge whether the alignment is off in certain dimensions.
