If you're asking whether you can provide speed in tacho counts per second, yes you can; you should use SpeedNativeUnits
. So something like:
tank_pair.on (left_speed = SpeedNativeUnits(speed + error), right_speed = SpeedNativeUnits(speed - error))
The units are documented here for more info: https://python-ev3dev.readthedocs.io/en/ev3dev-stretch/motors.html#units
Hello WasabiFan,
Thank you for your prompt answer. but it is not exactly what I mean. What I like to know for both motors ( f.i large_motor_B and large_motor_C) is the tacho_counts/ time_unit.
With f.i. the following routine I will control the both motors large _motor_B.on(SpeedRPM(30)) large_motor_C.on(SpeedRPM(30))
How can I be informed about the tacho_counts/time_unit ?
I hope You can help me
Thank you in advance mario
Ah, sorry, I misunderstood. To read the current motor speed you can use the .speed
attribute of a Motor: https://ev3dev-lang.readthedocs.io/projects/python-ev3dev/en/ev3dev-stretch/motors.html#ev3dev2.motor.Motor.speed
If you are using a pair of motors (e.g. MoveTank
), you can use tank_pair.right_motor.speed
(or equivalently for left_motor
).

Problem solved. Thank you very much
kind regards Mario
Glad to hear it!
Question
How do you ...?
I have a question about tacho counts.
Is it possible to run the tacho motors based upon the tacho counts. for instance:
count_left = tacho_count_left count_right = tacho_count_right error = count_left - count_right tank_pair.on (left_speed = speed + error, right_speed = speed - error)
thank you in advance mario
