Build Your Own Vacuum Robot

“This is my first Vacuum Robot, which it’s main purpose is to allow anyone to have a cleaning robot without paying so much money, to learn how they work, to build a nice robot that you can modify, update …

How to Build an Arduino Self-balancing Robot

“Ever wonder how Segways work? This tutorial will show you how to build an Arduino self-balancing robot that balances itself — just like a Segway! To keep the robot balanced, the motors must counteract the fall of the robot. This action …

PropHelix - 3D POV Display

“People have always been fascinated by holographic representations. There are several ways to do this. In my project i use a spinning helix of LED strips. There are a total of 144 LEDs that can displays 17280 voxels with 16 …

“CleanSweep (couldn’t think of better name :P) is a smartphone controlled robot that cleans your house’s floor! The rotating mops on the front of the robot along with a foam roller (used to paint walls, not here) at …

How to Design Common Emitter Amplifier

“Amplifiers are used to increase the voltage and current of a weak signal to desired level.There are two types of amplifiers.They are given below. In DC amplifiers,if you increase the voltage of DC Signal then the current …

Spiderbot V2 - Robot Car

“Spiderbot V2 is an upgrade version of my last project: https://www.instructables.com/id/3D-printed-Transformers-Robot-Spiderbot/ . The Spiderbot is inspired by the “Transformers”. It is a RC quadruped robot and has two modes of operation: spider and vehicle, just like …

How to Make a DC Motor Speed Controller

“Previously I made a DC motor Speed Controller, the design was good but it could be used with only 12 V motors. Soon I needed to control 24 V motors, so I had to come up with a design I …
