Portland Community College | Portland, Oregon

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

Upon completion of the course students should be able to:

• Recognize pneumatic hazards and take appropriate measures to protect against them.
• Operate pneumatically-driven robots to perform automatic material handling tasks.
• Perform alignment of pneumatically actuated robot arms.
• Troubleshoot pneumatic system faults following a systematic methodology using schematics and knowledge of major components.

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.

The laboratory portion of the course will include laboratory activities. The purpose of the laboratory activities is to understand the construction and operation of pneumatic devices and circuits.  Students may develop skills in analysis and troubleshooting, skills in teamwork, and skills in oral and written communication.

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.
