It looks like you are adding a constant for noise, so it makes sense the envelope output is a constant offset from the clean. I would think you need to add gaussian noise to simulate more realistic noise. Guassian noise would be centered around the clean signal.

For more information on this, see the first paragraph of the SCI specification for Discovery Series. It is possible that your robot is one of the unlucky ones. Unfortunately, I'm not aware that the OSMO upgrade modules for ...

I don't think your code is doing what you think it's doing, so I would highly suggest you attach a debugger and step through your ...

I'm not sure if/how pyserial works with a bytearray, but the way it is typically done is with the struct library. Here is some sample code: import serial import struct ser = serial.Serial("/dev/ttyUSB0", 57600) # compute left and right wheel velocities right_vel = int(velocity + (rotation/2)) left_vel = int(velocity - (rotation/2)) cmd = struct....
