Thank you so much everyone for voting for James in the Toy Contest! He got first place and I won a $500 Shapeways voucher! Expect to see more robot instructables from me in the future! :D
So you want to make a robot? Don't know where to start? How about you learn how to make a robot with me and make James!
James was made as part of a Robotics Class I teach to a few high school students.
I called him James in memory of my late Grandfather James Manning Edwards who passed away 14-3-2013. He loved teaching and helping kids and died doing what he loved, hopefully this James will carry on that legacy.
Step 1: Gather your Components and Tools
If you are looking to buy this Prototyping Shield search on ebay for “arduino prototype shield uno” and you should see it. Alternatively you can buy a similar looking one from Core Electronics: http://tinyurl.com/brxjx5h
Step 2: Planning
Next you will want to sketch the shape of the robot body onto the protective sheet of the acrylic, this can be done easily with a pencil. If you do not have acrylic you could use; balsa wood, ply-board, foam-core, cardboard plastic containers or even food containers! You will also need to mark out where you want your servo to go. To cut out the hole for the servo drill four holes on each corner where you want to put the servo, this is to allow the blade of the saw to be easily maneuverered, preventing finger loss.
Step 3: Arduino Mounting Holes
Step 4: Ultrasonic Mounting Bracket
Step 5: Drivetrain
Step 8: Wiring the Motor Driver
Step 9: Connecting the Ultrasonic Sensor
Step 11: Code
To make the use of the ultrasonic sensor easier I have used the new ping library.
