Build Your Own Simple and Easy PICAXE Microcontroller Based Photovore Robot

February 4, 2010 by rwb, under Robotics.

Building a simple and easy microcontroller based robot is always a fascinating topic to be discussed, especially for the robotics newbie enthusiast. On this tutorial I will show you how to build your own microcontroller based robot which known as a photovore or you could call it as the light chaser robot using the simplest possible circuit for the microcontroller based robot brain, locomotion motor and the sensor.

Build Your Own Microcontroller Based PID Control Line Follower Robot (LFR) – Second Part

August 30, 2009 by rwb, under Robotics.

One of the interesting parts in building the Line Follower Robot is; you could start it with a very simple version by using just two transistors with the LED and LDR for sensor (Build Your Own Transistor Based Mobile Line Follower Robot - First Part) and enhance it to the programmable version that use microcontroller as the brain for controlling the robot. The reason of using the microcontroller for the Line Follower Robot is we need to make more robust, reliable and flexible robot which you could not have it from the discrete electronics component robot without changing most of the electronic circuit design.

Build Your Own Transistor Based Mobile Line Follower Robot (LFR) – First Part

July 11, 2009 by rwb, under Robotics.

The mobile line follower robot is a type of mobile robot with only has one specific task which is to follow the line made with black tape over the white background or vise verse. The LFR perhaps is one of the most popular robot build by the roboticists. What makes this LFR is so popular, I think because of its simplicity and yet it could be used as the teaching tools of how we could implement the industrial standard control system such as the PID (Proportional Integral Deferential) control system on this robot. Another factor probably is the increase of the LFR annual tournament conducted in many countries. (more…)

Behavior Based Artificial Intelligent Mobile Robot with Sharp GP2D120 Distance Measuring Sensor - BRAM Part 2

June 8, 2009 by rwb, under Robotics.

What is the intelligent anyway; could we categories how the bees building their tiny hexagonal compound nest, ants searching for their food or birds migration using precision navigation over continental are the intelligent acts; or we as the human being with our cultures and civilizations is the only one that can be categories as the intelligent being? These kinds of question probably will not have satisfied answer as the answer is more philosophy terms rather than physics or mathematics law; therefore I think anyone could give their own opinion to this question.

Building BRAM your first Autonomous Mobile Robot using Microchip PIC Microcontroller – Part 1

May 25, 2009 by rwb, under Robotics.

Have you ever thought that most of our perception about the robot is based on the Hollywood movie! The famous 3CPO and R2D2 from Star Wars until the little cute garbage compacting robot named WALL-E; all of these machines are example of our dreams or should I say our quest to what we all think about the robot should be. Although the robot that we are going to build here is still far away from the technologies shown on those movies but at least it will give you an introductory to the robotics world. (more…)

Basic Servo Motor Controlling with Microchip PIC Microcontroller

February 17, 2009 by rwb, under Robotics.

The servo motor is widely used in model hobbyist such as airplane R/C model for moving the rudder, ailerons, elevators and acceleration control or in the car R/C model for steering and acceleration control. In this tutorial we will learn how to control the servo motor as well as the simple close loop control algorithm for this servo motor. (more…)
