OBSTACLES AVOIDING ROBORT USING ARDUINO And ULTRASONICS SENSER  By Ashish NARAYAN Obstacle Avoiding Robot  is an intelligent device which can automatically sense the obstacle in front of it and avoid them by turning itself in another direction. This design allows the robot to navigate in unknown environment by avoiding collisions, which is a primary requirement for any autonomous mobile robot. The application of Obstacle Avoiding robot is not limited and it is used in most of the military organization now which helps carry out many risky jobs that cannot be done by any soldiers. We previously built  Obstacle Avoiding Robot using Raspberry Pi  and  using PIC Microcontroller.  This time we will use  Arduino and Ultrasonic Sensor to build an Obstacle Avoider.  Here an Ultrasonic sensor is used to sense the obstacles in the path by calculating the distance between the robot and obstacle. If robot finds any obstacle it changes the directio...

DIY Arduino CNC Drawing Machine

DIY Arduino CNC Drawing Machine By Ashish Narayan Hello Guys, In this instructable I'm going to show you how to make an Arduino CNC plotter from old DVD writers. This is an amazing machine. You can make this machine for your school, college science project. It can write and draw anything. This is also very easy to make. So let's get started. If you like this project then please do vote for me guys. I really need your support :) Here's the demonstration and tutorial video. Step 1: Parts List We need this following parts to make this CNC plotter. Parts list: Old DVD writer (2x) Arduino Nano. L293D Motor Driver IC (2x) IC Base (2x) Micro Servo Motor. PCB Board Male And Female Header Pin. Barrel Socket. Acrylic Sheet 3mm Tools List: Solder iron. Super Glue. Mini Handsaw. Sandpaper. Ruler. Marker Pen. STEP 2 : Making the Pieces for Frame Here I'm using the acrylic sheet to make the frame fo...
