Bob the Robot - Arduino Robot Framework

Hello there fellow makers!

I've been looking for a nice robot framework and I've tried out many of these ... eventually (like most programmers do ) I've decided that I should develop my own robot framework!

So What it is so special about 'Bob The Robot' ?

• It uses two Ultrasonic Sensors so your robot can respond faster
• It uses a pair of geared n20 motors ( I use 1:100 reduction ) so you can get some power and nice speed
• Wheels, Frame and robot body can be 3D printed
• It's cheap!

This robots is part of my robot swarm project, so you can build more than one :)

To build a Bob you'll need :

• 3D print the frame, wheels and some more parts which can be found here http://www.thingiverse.com/thing:1409401
• m3 screws (10mm should be fine) and nuts
• 2x 60mm x 3.5mm Mechanical Nitrile Rubber O Ring Oil Seal W6 ( for tires )
• Brass Knurl Nuts M3*4mm (used for the m3 screws)

You'll also need the following parts for electronics :

• Arduino nano
• Arduino nano sensor shield
• Mini L293D Motor Shield
• 2x Ultrasonic HC-SR04 Sensor
• 2x n20 100RPM Mini Metal Gear Motor
• Battery to power the whole thing, I’ve used Wild Scorpion 7.4V 1100mAh due to its compact size
• Mini 2 Pin SPST ON-OFF Switch 8.5x13.5MM ( can be found on ebay)
• Some wires to connect the modules (mostly female-to-female )

Now you'll have to connect all the parts together and write some code, I'll post some code samples soon, so stay tuned!
