As a result of starting the Young Roboteers club, we've started to get asked lots of questions about where to begin building a robot, where do we get parts from, what do you need to know etc. Most of the questions have been coming from Home Educators who want to know more to enable their children who are interested in building robots to be able to build and code. Some of them don't know the first thing about building a robot but they are very eager to learn.
So to help beginners I've started up a group on Facebook aimed at Home Educators who want to know more about how to build basic robots, the idea behind the group is we share links, articles and answer questions about robots. Provide advice on where to find out more, kits worth sourcing etc, if you're interested in the group you can find us here Home Ed - Robot Learning Resource.
The diagram above and the following information formed part of an information sheet we handed out to our Young Roboteers on Week 2, in order to give them an idea of what is under the cover of a basic robot.
"The above schematic looks at a design for a simple Remote Controlled (R.C.) robot, this is a basic design and will only go right and left and forwards and backwards. Weapons and other items can be added but more components will be required.
The schematic shows how the power goes from the battery to the motor controller. The receiver will pick up the control information from the transmitter - for example the direction you want to drive in - and it will signal that information back to the motor controller. The motor controller will then process this information, and vary the voltage and direction going to the motors.
By varying the voltage going to the motors, you will be able to drive the robot at different speeds and turn it left and right like a tank. In this example, we are using 2 motors - 1 on each side.
More Information - You may find the YouTube video below on ‘How to Make a Simple Remote Controlled Robot Car at Home in 30 Minutes’ interesting. It should be added that the 30 minutes it states requires you to have the tools and components ready to go.
This link http://embedjournal.com/make-a-rc-robot-car/ takes you to a page that walks you through the building and testing of an R.C. Robot and is full of useful information."
