InMoov Head

 

 

head will track with both eyes and neck using 3 PID - it will have manual mode with joystick ?

PARTS

  • 3 Servos
  • Arduino
  • Netbook

Powering Pi Robots

DJUltis's picture

Alessandruino, this is for you. I noticed in the shoutbox that you were questioning how to properly power a Pi for robotics. 

So I've been working on the same thing and hope this info might give you a lot of help. 

 

Bill of materials:

- 2 or 3 cell Lipo Battery 3000mAh or above (I've been using a 5000mAh)

-USB Hub (I use one with a 5V 2A input)

-USB Micro cable (cheap cheap cheaper the better)

AdafruitMotorShield Service

javadoc

The  Adafruit Motor Shield is a service which will create a number of sub services.  It will create 4 Motor, 2 Servo, and 1 Arduino service.  This shield uses its own library, so MRLComm.ino will need to be modified.
Fortunately, the Arduino service will have the modified MRLComm.ino pre loaded in its editor.  This will need to be compiled & uploaded into the Arduino.

Examples:

[[service/AdafruitMotorShield.py]]

Network Problems

myrobotlab.org is hosted on Amazons AWS cloud services - guess where ? :(


InMoov / Python Service WORKY ! - Build 1694

GroG's picture

The Python service had a bug which did not allow callbacks from other Services.  Listeners could be set up which were supposed to call different methods in Python, but ended up only calling the first called method.

an Example would be :


Custom power boards for InMoov Servos

So I know this is site is about MRL not InMoov hardware but I wanted to share the custom power distribution boards I built with other InMoov builders.

I originally wanted to use my Adafruit 16 port servo controller boards with the InMoov service so I could put one at each of the elbows and connect up the servos to keep it nice and simple, no additional tangle of wires. Those boards aren't integrated yet with InMoov, so I had to look for other options for get my bot ready for Makerfaire.
