Have you ever wanted to design mechanisms that move really heavy or large things simply and easily? Do you have any applications that call for controlled linear motion? Are you frustrated with an engineering education that left out a practical grounding in fluid power? Come to Artisan's Asylum in February and learn how to design and assemble pneumatic and hydraulic systems!
Most engineers, designers and hobbyists are familiar with electric motors and their limitations. As a rule, motors tend to spin too quickly for most applications without substantial gearing, they tend to be fairly weak for their size, and they can be very complicated to control for amateurs. They're great for small, simple projects, but stop being as useful when projects start scaling up in size. Pneumatic and hydraulic systems pick up where electric motors leave off!
Pneumatic (air-powered) and hydraulic (liquid-powered) power transmission systems can simply and easily generate hundreds, to thousands, to tens of thousands of pounds of force instantaneously, and hold those forces indefinitely. They can be incredibly easy to assemble (once you know what parts to order), they're easy to control with simple relay circuits, and they're a breeze to design compared to electric systems. The big challenges involved in making use of them are knowing enough about them to design and assemble them safely, getting to know the symbolic language in which their circuits are drawn, knowing where to source components, and getting experience by making enough circuits to get used to the process.
This class will introduce students to the theory, design, and practical assembly of pneumatic and hydraulic circuits. Students will be taught the underlying principles behind each style of power transmission, will get to assemble several different circuits of each type of power transmission, will get to design their own circuits, and will go through the process of sourcing components from fluid power vendors.
Note: This class is offered as a full 8-course introduction to fluid power systems, but students can choose to participate in either pneumatics or hydraulics individually.
The goal of this class will be to give students a robust introduction to hydraulic and pneumatic systems. Students should be able to assemble hydraulic and pneumatic systems given standard schematics, and should be able to design basic fluid power systems independently by the end of the class.
No previous experience necessary.
All hydraulic and pneumatic system components will be provided as class items, and will remain at Artisan's Asylum.
What to Bring:
Students should wear clothing appropriate for a shop environment. On days where the class works with hydraulic systems, students should expect to get hydraulic oil on their clothes and skin. Students should wear work clothing they are willing to throw away at the end of class in case it gets too oily.
Gui Cavalcanti is the co-founder and President of Artisan's Asylum. Currently, he's leading the mechanical design of Stompy, a 4,000 pound, 18-foot-wide, 10-foot-tall, 6-legged hydraulic walking robot that seats two, developed by Project Hexapod (a company he cofounded with James Whong and Dan Cody). He worked as a robotics engineer and systems integrator at Boston Dynamics, working on cutting edge mechanical design and systems integration for highly dynamic legged robots like BigDog, AlphaDog, and PETMAN. He was the Systems Integrator for the LS3 project, coordinating the joint engineering and development of multiple subcontractors and engineers. Over the course of his career he has also developed the mechanical systems for a robotic tuna, several robotic snakes, an ornithopter, and other robotic animals.
