Telepresence Robot using Microchip PIC16F1829 and Atmel AVR ATmega168 I2C Smart DC Motor Controller Microcontroller – Part 2
September 5, 2013 by rwb, under Robotics.
The I2C (read as I square C) smart DC motor controller is designed using the Atmel 8-bit AVR Atmega168 microcontroller and configured to act as the I2C slave device where it could be controlled by other microcontroller or microprocessor through the I2C SDA (serial data) and SCL (serial clock) interface. In the first part we have accomplished a basic DC motor controller tasks i.e. differential steering and speed control using pulse width modulation (PWM). (more…)

The Line Follower Robot with Texas Instruments 16-Bit MSP430G2231 Microcontroller
September 11, 2011 by rwb, under Robotics.
When Texas Instruments (TI) introduced their new value line 16-bit microcontroller complete with the programmer and development board named MSP430 Value Line LaunchPad in the mid of 2010 for only USD 4.30 include the shipping cost, this make it as the cheapest programmer and development board platform that you could ever find in the market. Therefore the introduction of the MSP430 value line LaunchPad development board make a tremendous impact especially among the electronics hobbyist, students, and enthusiast because now the big boy (TI) is seriously taking part in the electronic hobbyist market and directly compete their 16-bit class value line microcontrollers to the 8-bit class microcontrollers which are mostly dominated by Atmel and Microchip.

The LM324 Quad Op-Amp Line Follower Robot with Pulse Width Modulation
January 14, 2011 by rwb, under Robotics.
Designing a simple and yet functional Line Follower Robot (LFR) is always a fascinating and challenging subject to be learned, the LFR actually could be implemented in many ways start from a simple two transistors to a sophisticated PID (Proportional, Integrate and Differential) which take advantage of the programmable feature of microcontroller to calculate the PID equation to successfully navigate the black track line on a white background surface.

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.
