+<your_obj_name>.send_power_on()

+<your_obj_name>.set_power(power_state_command=<True/False>)

+Turn on/off a WHILL. `power_state_command` is a bool with `True` to power WHILL on.

+Manipulate a WHILL via this command.
+Both `front` and `side` are integer values with range -100 ~ 100.

-Both `front` and `side` are integer values with range -100 ~ 100.
+Control the speed of a WHILL directly via this command. (Available since v1.3.0)
+`front` is  integer values with range -500 ~ 1500 [0.004km/h].
+`side` is integer values with range -750 ~ 750 [0.004km/h].
+**Attention:**
+WHILL moves so quickly using SetVelocity command and so pay enough attention to use SetVelocity command. Basically, send this command to increase speed gradually.
