Making a self-balancing robot using Arduino

Posted on May 22, 2017 by R-B Leave a comment

Two-wheel self-balancing robots are pretty cool and could be challenging to make for beginners. Joop Brokking describes the build process of his amazingly stable self-balancing robot in a video tutorial posted below. The robot uses two stepper motors for precise motion that is controlled by an Arduino board. The angular inclinations data are derived using a MPU6050 gyro/accelerometer. You can download the design files and firmware from Joop’s website. Joop’s YouTube video tutorial is posted below:

Arduino controlled rover with FPV live video

Posted on January 30, 2017 by R-B Leave a comment

Tamas is a 17 years old electronics enthusiast from Hungary. His latest creation, which he shared on Instructables, is an Arduino-powered rover that can be controlled with brainwaves or a joystick. The best part of it is, while it’s being operated, you will also have access to a live video stream from the mounted camera via your pair of virtual reality glasses. This is an all terrain vehicle, that means that you can control it on snow, sand, any kind of ground, wet surface and of course indoors. It is powered by two 18650 lithium-ion batteries with a capacity of 2600

Making a simple follow-me robot

Saurav Chakraborty has shared his making of a very basic DIY follow-me robot that uses no microcontroller. It uses two sets of IR photodiodes and an IR LED to sense the presence of an object in fron of it. When the object is sensed, two DC motors are turned on using transistor switches and the robot moves forward. The robot can also follow left and right path based on the motion of the front object.

FPGA-controlled robot solves Rubik’s cube

Alex Whiteway, Sungjoon Park, and Rameez Qurashi‘s final project for their ECE 5760 course at Cornell was FPGA-controlled mechanical arms to solve Rubik’s cube. While the arms rotate the cube, each cube face is scanned by a camera and the scanned data are passed into a Rubik’s cube solving algorithm, which then computes what the next moves would be towards solving the cube. The move instructions are sent to the FPGA, which in turn sends PWM signals to the servos to rotate the cube accordingly. They write, A variety of Rubik’s cube solvers (including a few FPGA implementations) have been

Four phase stepper motor controller

Rajkumar Sharma shares his unipolar 4-phase stepper motor controller board on Electronics Lab website. Unipolar 4-Phase Stepper Motor Controller Board will help you control a Stepper Motor or 4 individual Solenoids. This circuit consisting of transistors that serve as current amplifier and also diode to prevent damaging back EMF, circuit uses Darlington transistors to provide high current capacity to unipolar stepper motor. Just provide sequence of pulse using Micro-Controller or descript circuit to roll out the unipolar motor. On board High Watt resistor to control the current, value of the resistor can be set as per your load current requirement.
