Tutorial: Robotic Motor Control

Tutorial: Robotic Motor Control
In this article the author will show you how to build A Robot by adding the electronics necessary to control the speed and direction of both motors on the robotic chassis. The two main additions in this portion of the project are a microcontroller and a motor controller IC. Since we now have a beautiful robotic ...

Stepper motor Introduction for Beginners

Stepper motor Introduction for Beginners
Stepper motors (also called step motors) are electronic motors that offer precise rotation control. The size of the increment is measured in degrees and can vary depending on the application. Typical increments are 0.9 or 1.8 degrees, with 400 or 200 increments thus representing a full circle. Stepper motors have been used in computer hard drive ...

Multiwii Trimming Accelerometer for Auto-level Flight

Multiwii Trimming Accelerometer for Auto-level Flight
Before following this tutorial make sure your transmitter is properly trimmed out using normal (Gyro/Acro) flight mode and adjusting the trim dials on your transmitter. Without properly trimming your transmitter to neutral your transmitter will be commanding the quadcopter to move when you intention is for the copter to maintain a level attitude. What is ...

Robotic Light Sensors

Robotic Light Sensors
A light sensor has the role to detect the light and the result is translated into output analog value. The sensor output depends by light intensity and has low or high values. The robot can be programmed to react when the light sensor detects a certain amount of light. In some words, a light sensor is ...

How Does I2C Connection Works 101

How Does I2C Connection Works 101
I2C Connection 101 If you try to put 5 or more sensors on your robot, your MCU will soon be out of I/O pins in no time. For example a Sumovore with the Atmel brain board, can contain 4-5 edge detectors, 2 IR LEDS, 2 IR receivers, 2 motors, and 6 user programmable LEDs. That’s ...
