Octocopter motor failure testbench to test Nominal Instrumentation Package

I built a small octocopter motor failure testbench in Streamlit to try out the new open source Nominal Instro package.

  • Streamlit = mission console (motor controls, hardware visualizations).
  • Instro = instrument layer (InstroDAQ reads/writes, channel aliases, etc).

I’m new to hardware engineering, and I’ve been finding it frustrating that I need to relearn how to use each hardware driver. Instro seems cool because it gives me a hardware abstraction so that I can write my testing code once and swap out the underlying hardware later.

Moving to my real LabJack driver is just swapping out this one line of code below.

from instro.daq import InstroDAQ

driver = SimulatedLabJackT7(device_id="470010000")
# driver = LabJackTSeriesDriver(device_id="470010000")  # real bench

daq = InstroDAQ(name="drone_bench", driver=driver)
daq.write_analog_value("m1_cmd", 0.5)
measurement = daq.read_analog()

This looks great! It would be really cool to visualize the octocopter’s position (x, y, z) throughout the entire process.

I’d love to see this in action with multiple different types of sensors/hardware. I’m currently working on an RC submarine build, and have been thinking about implementing a recovery feature in the event of a pump or motor failure. Something like this would definitely help with designing.

Sick!
