• 10 Years of dev experience• Mostly Java and Android • I work for Entelect• I try to do cool stuff in my free
time
How many people here are interested in building robots?
Why haven’t you?
• It’s too hard• I don’t know where to start• It costs too much• I don’t have time
You know Javascript
Node + Robotics = Nodebots
You already have most of the skills
Lets build a robot
What is a robot?A robot is a mechanical or virtual artificial agent, usually an electro-mechanical machine that is
guided by a computer program or electronic circuitry. Robots can be autonomous or semi-autonomous and range from humanoids such as Honda's Advanced Step in Innovative
Mobility (ASIMO) and TOSY's TOSY Ping Pong Playing Robot (TOPIO) to industrial robots, collectively programmed swarm robots, and even microscopic nano robots.

What do you need
Hardware
Electronics
Software
Patience
HardwareChassis with wheels and space to mount stuff.
ElectronicsRaspberry Pi B+
Why?
• Inexpensive
• Lots of GPIO
• More computing power than you need
• Easy to add a camera for computer vision or video streaming

What does this cost?Chassis (With motors, wheels, chassis and battery box)
R249.95
Raspberry Pi B+ R504.67
SparkFun Pi Wedge B+ R132.95
Breadboard Jumper Wire (65PCs Pack) R43.78
Motor driver R129.95
Distance sensor R39.95

Step 1Assemble the hardware
Step 2Wire everything up
Step 3 – Program itThe part I imagine you are more interested in
What are we going to use?
Client• Johnny-five• JS Robotics library
Hardware• Raspio-io• Talks to the Raspberry Pi
Component specific libraries• R-pi-usonic
Installing1. Set up the Pi (Install raspbian, set up SSH, wifi, etc)
2. Install node.js
3. Install Johnny-five (npm install johnny-five)
4. Setup a board (npm install raspi-io)
5. That’s it
Simulation
Initialising Johnny-Five
Making it move
Bonus – Controlling it
Adding sensors
Logic
What next
• Improve the algorithm• Add more sensors• Give it a goal• Give it personality• Make the hardware better (Better chassis, stronger motors, etc)
