#7 Automated Stairs
by Rishi Gangwar
The stairs uses an rack and pinion mechanism to control all the stairs and is supported by sliders which can be altered according to the loading requirements on manufacturing.
it uses an stepper motor whose torque can also be alterd while installing to meet the loading condition.

you want the same design in the picture or not.
and you didn't pay for this sir.

The project is almost complete but please increase the price and specify the capacity to carry, it is vital in order to complete its last phase and for me to finally submit.
and plz provide some technical details i.e weight,height etc
i can do it with electrical equipment but kindly increase design cost at-least $300-$400
Hello Aly
How much is the height from the yard to the floor?

Please explain how to build a product with maybe patent protection? And...the development of the product will take not les than 2 months ant will cost just for the engineering not les than 10.000 Euro. So? Do not be so naiv please! However we speak about mashinery and transportation ot peaple, the requirements are not joke,
This product is only available in the UK. I'm trying to build this in my house for my son. It will not be a commercial product, just something that I can contract its design and build. My intention is to have three contests: 1) Engineering Drawing, 2) Engineering Design, including materials, electro-hydronic mechanizm and operations, and 3) Build.
This context is for the first step, the drawing only

Do u need electro-hydraulic operation?
I am prepare to work on this project.
This is not a DIY project. This is serious engineering with liabilities and patent infringement possibilities.
I agree with both comments before me which should explain why this is not a pre-pay as well.

How is this a contest? It looks to me like a reverse engineering job. Something that is already available. You might want to check if there is a patent on this product already.
An interesting project, but it is worth a lot more than $100!

To help you get started on the RTSM for the project, I would like to point out that detailed explanations about the procedures used in the example spreadsheet can be found in the book attached along with the project description:
*Example 8-16, pp.266-272*
Please follow the instruction to understand how it is implemented. You might need to refer Chapter 7 for the solar heat gain, such as equation 7-32.
Once you understand the example, The project should be much easier.
Please let me know if you have any questions.
ASAP design needed
Need to Sumit this project to teacher
