Re: Ultrasonic Interference
Hmm that is interesting, havent seen that before. Couple ideas for additional tests.
Have you tried placing a shield between the motor and the sensor (and any wall the sensor is using) to reflect or absorb any interfering sound?
Have you tried running a different RS-775 directly off a separate battery (using a breakout box or something) while using the sensor on the robot? (if you don't get interference in this case the RS-775 are likely interfering with the electrical system on your robot)
This is an interesting case to investigate, but ultimately I would just pulse the ultrasonics a couple times to check/adjust my distance (at the end of an encoder segment) and not run the RS-775 during these readings.
