L293D is 16 PIN Motor Driver IC. It’s very useful in driving DC and stepper Motor for Robotic cars. It can drive two motors. 

There are many Motor driver boards designed using L293D available in the market. If you are concerned about size and space then consider soldering L293D by yourself, Benefit you can save money, space and avoid additional components.

 




This is simple PIN soldering detail as given below?

 

1.    Solder and join PIN 1,9,8,16 and connect to 5V power supply( Red Wire), This will drive both Motors on 5V

2.    Join PIN 4, 5, 12, and 13 to ground. Solder them all together. Connect to the ground of power supply (Black wire)

3.    PIN 2 and 7 are data signal input from Raspberry PI GPIO PIN to drive Motor 1 connected to PIN 3 and 6

4.    PIN 10 and 15 are data signal from Raspberry PI GPIO PIN to drive Motor 2 connected to PIN 11 and 14

 

 

ROBOTIC CAR 4WD CHASSIS DESIGN 

 

This is a simple and easy four-wheel multidirectional car chassis design for robotics. Without using any additional servo Motors for right and left turn. This diagram shows how to connect four Motors to one L293D Motor driver. 

 

As explained earlier diagram, Input1,2,3 and 4 are data input signals from Raspberry PI GPIO PIN.




 

 

In four wheel car design, the main challenge is a right to turn and left turn. To overcome this challenge you need to make four wheels drive, use four DC motors, one for each wheel, and a chassis design that looks similar to this. Length needs to be greater than the width. Left wheels are connected to the same output of Motor Driver, so they drive in one direction, the same for the right wheel. When the left wheel turn in one direction and the right wheel turn in the other direction, a car makes a right or left turn.

Why the robotic class  is important for school kids? Kids pick out up a lot of habits and developments from faculty. School is the number one center of studying for kids and consequently, maximum kids begin their studying and entrepreneurial journey from their school. Having instructions on a topic like robotics will help faculties to encourage kids to attempt various things. How to make the kids future-ready? Robotics is a discipline this is developing at an exponential price and very quickly, we can all see automation becoming an everyday issue. Therefore, encouraging kids to soak up robotics faculty tasks will go an extended manner in assisting them to put together for destiny. As a generation grows, numerous jobs are going out of the marketplace because newer methods are derived to carry out the equal factor. This has caused a recession in regards to some fields. But one discipline which appears to be going nowhere but up is robotics. It encourages kids to analyze new ma...
