Step 1: mechanical design and partsFirst, you must design and create mechanical parts.I provide designs made in CAD and pictures

Step 2: trayPaler t is a platform similar to a platform on which the car will stay or lift. It is designed so that all cars are suitable for the pallet.Step 3: sprocket

Sprocket or sprocket, which is made of mild steel plate and formed in the manufacturing process. It is a special-shaped wheel with teeth, embedded gears and even sprockets, which mesh with chains, tracks or other perforated or concave materials. The term "sprocket" generally applies to any chain with radial protrusions that mesh with the chain passing through it. The difference between sprocket and gear is that sprocket is never directly meshed, while sprocket is different from pulley. Sprocket has teeth and pulley is smooth.Sprockets have a variety of designs that are said to maximize efficiency. Each is created by its creator. Sprockets usually have no flanges. Some sprockets for timing belts have flanges to center the timing belt. Sprockets and chains can also be used for power transmission from one shaft to another. Slipping is not allowed. Sprockets replace chain belts or ropes, and sprockets replace pulleys. They can run at high speed, and some forms of chains can remain noiseless even at high speed.Step 4: roller chain

Roller chain or bushing roller chain is a kind of chain drive. It is most commonly used to transmit mechanical power on many household, industrial and agricultural machinery, including conveyors, wires and pipes - plotter, printer, automobile, motorcycle and bicycle. It consists of a series of short cylindrical rollers fixed together by side links. It is driven by a gear called a sprocket. This is a simple, reliable and effective power transmission mode.Step 5: bushing bearing

The bushing, also known as the bushing, is a separate plain bearing inserted into the housing to provide a bearing surface for rotational applications; This is the most common form of sliding bearing. Common designs include solid (sleeve and flange), split and tight bushings. Sleeve, open or clamped bushing is only a "sleeve" of material with inner diameter (ID), outer diameter (OD) and length. The difference between the three types is that the solid sleeve bushing is always solid, and there is a cut in the length direction of the split bushing, while the clamping bearing is similar to the split bushing, but there is bite (or compression) on the cut. The flange bushing is a sleeve bushing with a flange extending radially outward from od at one end. The flange is used to reliably position the bushing or provide the thrust bearing surface when installing the bushing.

Step 6: l-connectorUse a square bar to connect the pallet to the bar.Step 7: square bar

Secure the l-connector together.Step 8: beam barUsed

Step 9: power axisProvide power.Step 10: frame

It is the whole rotating system of the structure.Step 11: pallet assemblyA pallet base assembled with beams to create a single pallet.

Step 12: final mechanical assemblyFinally, all pallets are connected to the frame and motor connectors are assembled.Now it's time for electronic circuits and programming.

Step 13: electronic design and programming (Arduino)We use ardiuno (our plan). The next step will show the electronic parts we use.The system functions are:

The system consists of a keypad for input (including calibration).The 16x2 LCD displays the input value and current position.The motor is a stepping motor driven by a large capacity driver.

Data is stored in EEPROM for nonvolatile storage.Motor independent (somewhat) circuit and program design.Use a bipolar stepper.

Step 14: circuitThe circuit uses ATMEL atmega328 (Atmega168 or any standard Arduino board can also be used). It uses a standard library to connect with LCD, keyboard and motor driver.The drive requirements are based on the actual physical scale of the rotating system. The required torque must be calculated in advance and the motor must be selected accordingly. Multiple motors can be driven with the same driver input. Each motor uses a separate driver. More torque may be required.

The circuit diagram and deformation scheme are given.Step 15: Programmingit

Functions include:Adjustable motor speed (RPM).The value per revolution of any bipolar stepper motor to be used can change the number of steps. (although 200 SPR or 1.8 degree stepper motors are preferred).

Adjustable number of stages.A separate movement angle for each stage (therefore, any errors in manufacturing can be compensated programmatically).Two way movement enables efficient operation.

The offset that can be set.The settings are stored, so adjustments are only required on the first run.To program the chip (or Arduino), you need to program the Arduino ide or Arduino Builder (or avrdude)

Programming steps:Download Arduino Bulider.Open and select the downloaded hex file from here.

Select the port and the appropriate board (I use Arduino UNO).Upload hex file.Good.

There is a good article on Arduino dev about uploading hex to Arduino.Project source code - GitHub source code. You want to compile and upload it using Arduino ide.Step 16: work video

Step 17: cost accountingThe total cost is approximately INR 9000 (approximately USD 140 according to dt-21 / 06 / 17).Component costs vary with time and location. Therefore, please check your local price.
