Why my Makeblock robot doesn't move when I set low
motor speed
This article applies to: mBot, mBot Ranger, Starter, Ultimate, Ultimate 2.0
For example, we set the speed value 50 for mBot, here the "50" is not the real speed value. The
real running speed depends on the voltage and speed value.
Here we take mBot as an example:
The setting speed is 50, and the maximum speed is 255.
The battery is 3.7V, and it is fully charged.
The rated voltage is 6V for TT Geared Motor, and the no load speed: 200RPM±10%
)
Thus, setting speed to 50 might be too slow for TT Geared Motors to run. Try 100 above to have a
look.
For other robot kits, setting speed at 20 will not let it move.
