Bob the Robotic Head #hackfriday

Mike writes:

Hack Friday started a couple months ago buying a robotic head.  It comes with two servo motors and two electric motors.  About the same time I bought an Adafruit motor shield to control the head via an Arduino.  I have not had time to wire it up with other projects like the Cylon Pumpkin.  With Halloween over, I wanted to focus on the robot. Helping was receipt today of another Adafruit order from this past Sunday when they had a 10% off sale for Hack Friday.  Just in time!

The head is driven with the motor shield’s two servo outputs and two of the four motor controllers.  For now, a potentiometer is read to control the motor and a rotary encoder, interrupt driven, selects which motor to control (could be done with 4 potentiometers possibly better).  The motor shield leaves enough Arduino pins free (all analog pins and digital pin 2 which is interrupt controllable).  Eventually the head will respond to sensors and possibly talk via an Emic speech board coming from a sale at Make.

Making the hookup much more enjoyable is my new Hakko soldering iron – near instant controlled heat, making the old Radio Shack model seem so 1976.

I’m looking forward to seeing this project up and running (and talking) — it looks great so far!


Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
