A python robotic framework and tools
Project description
pyGecko
My robot software.
- Doesn’t use ROS, ROS is a pain to install and maintain on macOS 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
Documentation
Note: This re-write is still very early and not fully running yet, just parts.
The documentation can be found here.
Install
Use brew or apt-get to install these dependencies:
zeromq
opencv 3.x
pip
The recommended way to install this library is:
pip install pygecko
Development
If you wish to develop and submit git-pulls, you can do:
git clone https://github.com/walchko/pygecko cd pygecko pip install -e .
Testing
Since I have both python2 and python3 installed, I need to test with both:
python2 -m nose *.py python3 -m nose *.py
Warning: python3 is not fully supported yet, it is giving me problems. Only python2 is currently supported.
Layout
pyGecko still in development
example/servers: main message server nodes
Speech server
Navigation server
Vision processing server
VideoOdometry server
bin: command line programs
topic reader/creator
bag play/record
image viewer
mjpeg streamer
keyboard controller
pygecko: mostly classes
bag
camera calibrator
chatbot
file storage
messages
pywit
audio
zmq
Tools
This directory contains several tools for the robot:
Executable |
Stable |
Description |
|---|---|---|
camera_calibrate.py |
Y |
performs camera calibration using either a chessboard or asymmetric circle target. Target patterns are in the patterns folder. |
topic.py |
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) |
video.py |
Y |
capture images or a video clip from a camera |
webserver.py |
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.
ToDo
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
quaternions - use/update
implement a simple dynamic html server that takes json data in and produces webpages of diagnostic/status info
History
pyGecko comes from my previous robotics projects that I have been working on for years. Why gecko?? I am from Florida and I remember seeing a lot of geckos running around when I was at college … my cats were scared of them.
