Excellent project. Have been mowing large areas with autonomous mowers for several years now and have often thought about monitoring engine RPM and reducing forward speed when it drops off by 10% or so and resume forward speed when it clears itself. Would be very useful for us. Perhaps a winter project…. Good luck!
PS - Those bumpers are an excellent idea.
