Introduction: Simple Arduino Robot - Block Programming for Kids
Arduino Robot project aims to enable kids to program their own robot through simple drag and drop block programming
Step 1: Overview
In this project we will use mBlock, that is a Scratch variant with the same drag-and-dropping style. mBlock is an open source and enable write programs to control the robot or give it some intelligence.
- From Extensions menu item
- Open Manage Extensions (short-cut Ctrl+shift+T)
- Click Available button and search for "Rover"
- Click Download
You can now write Arduino programs and build them direct from mBlock, from Edit menu switch to Arduino mode
Step 2: Part List
2 X DC Motors
2 X Wheels
1 X Caster (or old roll-on bottle)
1 X LED
1 X 220 Ohm Resistor
1 X 10 Ohm NTC Thermal Resistor (Optional to limit DC motors max current)
1 X 100uF Capacitor
1 X 1N4001 Diode
L293D Motor Driver (or other Arduino Motor driver extension)
IR Remote controller + IR receiver Diode
7.0volts Battery (or 4 x AA batteries)
Breadboard 400 Tie Point
Arduino Uno (or other supported Ardunio board)
Step 3: Building the Robot
Download the attached RobotBase.pdf and use a cutter and cardboard paper to cut the robot base. Then mount the motors and caster using hot glue.
Step 4: Wiring Diagram
Wire all components as the above diagram.
Step 5: Writing the Code
Start mBlock IDE in Arduino mode, and select Arduino Uno board from Boards menu. check Arduino Rover Extension page for more information on how to use.
Attached below arduino_rover.sb2 a complete sample for Arduino Robot code.
