Let's Make Robots!

The planning of a tiny autonomous SHR type robot.

I have built a SHR robot using an arduino and a L298N. Everything works fine although the motor driver is junk. However, I want to build another. One that is really small, and cheap to build. I have not bought any parts so everything I am saying is just thoughts in my head right now.

Remember that all these parts were (mentally) chosen due to their small size and cost.


Arduino Nano - $8  eBay  (Has PWM pins which would be used for servo, etc.)

Building my first robot... need help finding the correct motor shield

Hello, this is my first forum post! I'm in the process of building my first robot, and I'm not sure which motor shield to use. It will be a two wheeled autonomous robot that uses an Arduino Uno. I am using 2  1:120 geared motors. The robot will be similiar to the Bliss Robot (http://letsmakerobots.com/node/28477), just with a different ultrasonic sensor. I now of the Instant Robot Shield made by PICAXE, but I'm not sure if this is the best option for my robot.


Thank You!
