Automatic Door Mechanism
Introduction : We often visit, shopping malls, airports and other retail business stores, for shopping and other needs, In order to enter into the mall, or to come out, we should PUSH or PULL the door, in spite of carrying heavier shopping bags in hands, we feel uncomfortable to do so. But, this was the case earlier, now it’s all different. The technology is evolving day by day and we have come a long way in inventing a Robot to do all these sorts of things.
Are you wondering, what am I talking about? Well, let me open up. Most of the places, we could find a typical automatic sliding door which opens and closes, automatically when we pass by it. By looking at we wonder, how a door could
Now I Take a motor shaft and attach a shaft extension to it and then closes it with a circlip.
When we connect something, we should check if it is connected well. Now, I am picking a wheel block and attaching it to the extended shaft, then I am checking if it’s Rotating well, finally, I am closing it with a circlip. Perfect!! Now, I am going to attach another circlip to the wheel like this, and extending it with a shaft extension. Now, I am placing another circlip on it. I am Pressing it tightly once, these motor and wheel, are used to generate the circular motion, and this circular motion is converted into a linear motion by connecting extension blocks to the wheel. Now, I am going to pick a 70 extension block and connecting it to the wheel block like this, and I close it with a circlip. In the same way, I created another wheel block, and now, keep them aside. Let me Pick a 70 extension block and connect it with a 50 ext block like this, and I am going to attach another 70 extension block to it, then, I keep it
As a result, we can see an object looks like a door. I have applied the same process on the other wheel as well, and as you see, I am going to attach them to the motor blocks.
Now, I will Pick a base and attaches 4, 70 extension blocks at the corners of the Base, and then I am attaching the motor block to the base, towards the downside. In the same way, I am going to fix the another motor on the other side as well.
Now, we need to attach the sensors to the object. To do that, let me use another 50 extension block and a straight connector. I am going to Connect them on both the sides of the base. These 50 ext blocks are used to restrict the circular motion. Before moving ahead, I would like to explain you the concept of converting a circular motion into a linear motion which is used in this mechanism, but, before that, you need to understand what is circular and a Linear motion are. Circular motion is a movement of an object which rotates in a circular path or which rotates within a circumference of a circle. It can be uniform with a constant angular rate of rotation and speed or non uniform with a changing rate of

This process will be beneficial to discuss the properties of the each code, when I employed expert view procedure. In addition, the memo will be a guidance for me during second cycle coding, in which the researcher finds the patterns in codes and categories or themes (Miles, Huberman & Saldana, 2014). I will select anecdotes to support those categories I will observe in the data. In this way, I will describe categories and how the data display the preservice early childhood teachers’…

I am going to propose them my idea for the ability to reprogram their newest graphing calculator, the TI-84. Then I am going to contact a programing company, Manta, to have them reprogram the calculator for what I want it to do. But first I have to find a way to graph these functions. For this I want to have a new interface for the inverse functions, just like the interface for the functions on the TI-84. To graph the function on the calculator, I want to be able to take the function and make it into the inverse function graph by switch the x-value and y-value at every point.…

This mechanism implemented with two sesnors which can detect a surface under the robot and move the robot accordingly. If the edge is detected on a platform by right sensor the robot will turn to its left and vice versa. When the robot detects the edge on both the sides it moves backward untill it doesn’t detect any edge and then moves to the right side a little and repeats the above process. Line following robot : Now, lets design a line following robot, for that, I need to pick a 50 ext block and attch 2 straight connectors to it like this. then I am going to attach both the sensors to this 50 ext block, and then I am fixing this sensors at the frontside of the robot as you see.…

In the end, my diagram two was a representation of the actions made by the identified geometries of diagram one. For my final diagram, I thought of all the different ways i could transgress the original diagram and ideas of Richard Neutra. The first thing that I decided to evolve was moving from a central axis that all the shapes reacted to, to a central point where all the shapes could…

You may even create your own method. Cut the zip ties to your desired length and shape using a pair of strong pliers/ wire cutters. For the smallest fins I sewed with the fabric inside out forming almost a V shape with the two seams on the sides. I left a large enough hole on the tip of the V to turn the fabric right side out. Then pin the zips in place.…
