Journal 9/18 test model
This is a model based on the sunroof cassette. The end of the track is level with the stage deck while the other end is lifted up with a set of levers.
Like the patents, this design uses the the same force that moves it forward to prop the arms up and change the angel of the platform when it reaches the end of its track.
I still want to find a way to have a physical lock that can be done and undone by the same cylinder that move the platform. I want to have a structure that can remain safe should the pneumatic or hydraulic cylinder loses pressure.
Automated Trapdoor Proposal
Automated trapdoor proposal
Who am I :
I am Andrew Ng, a senior Entertainment Technology major specializing in Lighting and Technical Direction. I have 6 year of experience participating and mentoring in FIRST Robotics, and I want to work with automation, AutoCAD design, problem solving, and special effects. I will be the project manager and master carpenter for my project. I will be working with John McCullough to design and construct a life sized model to demonstrate proof of concept.
The Automated trapdoor
The automated trapdoor will be able to work with a trisket and stud wall platform deck for the theater. It can be triggered remotely from backstage or a control booth by actuating a piston with pneumatic or hydraulic power. It will create an opening in the platform that can allow access to elements under the deck.
Issues to address :
- Structural Safety
- Construction
- time
- automation safety
- automation mechanism
- Power
- parts and parameters
Solutions :
I will draft a design and make models to test mechanisms for the trapdoor. I will find parts and either obtain or build a proxy for the model. The project will be broken down into phases that should be more manageable. When concept model is put together a can-locking mechanism can be designed. I plan on using physical relays or a deadman switch and e-stop to prevent the trap door from closing on people.
