A python robotic framework and tools

Project description Requirements Status

My robot software.

  • Doesn’t use ROS, ROS is a pain to install and maintain on OSX and various linux systems
    • Uses some of the same ideas, but not RPC-XML
  • Uses Zero MQ instead of roscore
  • Uses OpenCV to process on-board or stream video off-board to remote
  • All of this runs on Raspberry Pi3

Note: This re-write is still very early and not fully running yet, just parts.


Use brew or apt-get to install:

  • zeromq
  • opencv 3.x
  • [optional] SDL 2.0 for PS4 joystick control


pip install pygecko


git clone
cd pygecko
pip install -e .


pyGecko still in development

  • servers: main nodes

    • Speech server
    • Navigation server
    • Vision processing server
    • VideoOdometry server
  • tools: command line programs

    • Topic reader/creator
    • bag play/record
    • image viewer
    • mjpeg streamer
    • keyboard
  • lib: mostly classes

    • bag
    • camera calibrator
    • chatbot
    • file storage
    • messages
    • microphone
    • zmq


This directory contains several tools for the robot:

Executable Stable Description Y performs camera calibration using either a chessboard or asymmetric circle target. Target patterns are in the patterns folder. N send various commands to the robot [work in progress]
image_view Y subscribe to image messages and display them for debugging
mjpeg-server Y create a web server which serves up an mjpeg stream from a camera. Any web browser on any device can see this stream (easier than image_view) Y capture images or a video clip from a camera N serve up a web page containing debugging and status info for the robot
bag_play/record Y saves messages to a file so they can be replayed off-line later
twist_keyboard Y simple keyboard interface to send twist messages to a robot

Note: Please take stable with a grain of salt … all of this is still in major development.

Note: There is some duplication between these, and it will eventually be sorted out.


  • fix speech … not sure best way to do this
  • better modularity for various robots … not sure how to do this
    • multiple robots use same/similar software … not sure how to best divide things up
  • mjpeg_server
    • only handles one connection at a time … make threaded?
    • sometimes the video stream is slow to load, but then it works fine
    • handle client disconnect (broken pipe - 32) better
  • opencvutils - replacing lib/ and move calibration stuff to it
    • these are good capabilities that can be used beyond just this library, make a stand alone library/tool
  • simplehtml - use for dynamic webpages
  • quaternions - use/update
  • implement a simple dynamic html server that takes json data in and produces webpages of diagnostic/status info


pyGecko comes from my previous robotics projects that I have been working on for years.
