TQFP PIC18F45550 Robot Platform (Bot Board)

A homemade PIC18F4550 TQFP Robot development board for experimenting and testing, it provides easy interface with various sensors and components. It is like a prototype board where you can test your awesome codes and ideas, without building the bot from scratch.

High Torque Motor - Low RPM

High Torque Motor , low RPM DC Motor

High Torque Motors

High torque motors are practically just a regular, internally commutated brushless DC Motors mounted with additional gears mechanism, to either increase the torque or to reduce the RPM (Revolutions per minute). These DC motors are quiet powerful and can be used in several hobbyist and industrial application. Read more about High torque motor gear box.

4 Wheeled Robot Design Basics and Challenges

4 Wheel Drive Robot Differential Steering Design challenges and chassis designing

4 Wheel Robot Design: This article deals with some of the design oriented challenges that come in the way of designing a 4 Wheel Robot that uses Differential Steering for taking turns (left and right) or to make a Complete 360 Degree in-place (pivot) rotation (zero-radius turning). Attention to some basic details can help a beginner to make an efficient robot without loss of much energy and torque.

Introduction To Microcontroller

What is a microcontroller ? Microcontroller in simple term refers to  a small computer on a single chip. Its like an artificial mind for any intelligent devices which is responsible for taking decisions. [eg your robot needs to take decisions, then a microcontroller would do that for us.] Microcontroller can be programmed , and has its own programming language and compilers. Hence in our robotic applications it is going to serve as a mind which will be responsible for taking all decisions.
