Schematics Best 5 Robotics Websites to Learn and Discuss PCB

Circuit

Robotics, a technology that combines knowledge of electronics, mechanical and software engineering is the most exciting field today. There are some really cool projects and applications using robots. Here are  some best websites for all robot enthusiasts as well as college students.

Go Robotics

This website started in 1998, is one of the most interesting websites on robotics. it has some really cool videos, circuit ideas and descriptions on how to build a robot from scratch and robotic gift ideas. This website has been mostly liked by hobbyists who play around with open source  and do it yourself projects, it is linked on social networks and has developed an online community to regularly contribute, work together and have  fun with robotics.

Robotics India

It is an online forum that connects the robotics enthusiasts in india. You can post an announcement, news or start discussion on any topic based on robots. The online community helps you to develop your robotic projects much faster by providing you information   on what's new, world's news, blogs etc. You can register yourself online.

Seattle Robotics

The encoder page of this website lists the with 'home-built' robot information on how the projects can be started and finished. Here' you may get ideas on how a machine actually moves or does something.  The list includes the name of the robotics projects. A brief description and link to its home page. It is a modest collection of cool places where you can see what people are doing and in many cases how they did it.

NASA Robotics Page

The robotics alliance project of  national aeronautics and space admisnistration (NASA) aims at creating a human, technical and programmatic resource of robotics capabilities to enable implementation of future robotics space exploration missions. Although the objective of this page is to support ameracan development and inspire high school students to pursue robotics. 

Society of Robots

It is a very resourceful collection of information on robotics books, projects tutorials and journals. It has different categories to give you in-depth information on the skills and hardware like microcontrollers, sensors,actuators, batteries etc. The small robotic projects like 50$ robot will be an excellent choice for a beginner to start with robotics.

Circuit BristleBot Schematics

It's been my passion to learn new things by hacking. So I construct mini-projects on materials available at hand.

Having difficulty in the past removing weights on minimotors, i've decide to build as simple bristlebot that rotates and created random movements.

You just need a bristle from a toothbrush, a minimotor with weights, a button cell battery and some adhesive tapes.

Here's the video:

Circuit Simple Line Following Mobot Schematics

A year ago I built a simple line following mobot. It doesn't use any microcontroller(Arduino, PIC, Atmel, etc.) and even logic ICs.

Simplest Line Following Mobot

This line following mobot uses basic electronic components. Actually, the circuit for this mobot is based on the previous project light/dark activated switch.

The chassis and wheels of the robot are recycled materials. The body is from a box of cookies and the wheels are from the container of wafer stick. I also added a wristband from one of presidential candidates last election for the additional traction of the wheel.

The whole circuit for this mobot is not mounted on a pcb nor a protoboard but on a mini-breadboard. I also uses scrap components for this mobot I found on my bin. 

 

The circuit on the mini-breadboard

This is the circuit of the simple line following mobot.

Basic components are used in this mobot. I uses the following components(all in pairs): bright leds, resistor, variable resistor, ldr, general purpose npn transistor, signal diode, spdt relay and a geared dc motor. 

Here are some pictures of the mobot parts:

This is a simple demo video showing the performance of the mobot:
