Open Source Garden/Generic Autonomous Robot (Python library)
OSGAR is lightweight multi-platform library targeting record and replay of
nodes (modules = sensors, robots, applications) logged into single file. It
has similar goals as ROS or ADTF, but is minimalistic. It should run on
different operating systems and also low end devices like Raspberry PI Zero.

Robot is set of modules. Every module has input and output ports, described
together with the connections in the config file. All ports are logged with
timestamp (microsecond resolution). The module is typically an instance of a
driver, whose init arguments are also in config file.

Collect data from sensor(s)
There is a osgar/record.py to run data collection based on given configuration file. If you would like to collect GPS data available on serial port use modified version of test-windows-gps.json for Windows or test-gps-imu.json for Linux.
python -m osgar.record config/test-windows-gps.json
To replay existing log use:
python -m osgar.replay --module <module name> <log file name>
