Course Description

Examines how compressed air is used in pneumatic components to actuate motion and how the starting, stopping, direction, and speed of the motion can be controlled. Covers troubleshooting of pneumatic system faults following a systematic methodology. Prerequisites: MT 111A.

Addendum to Course Description

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. 

Intended Outcomes for the course

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.

Course Activities and Design

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.

Outcome Assessment Strategies

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.
