I am trying to control a servo on my BB Blue with the rcpy library with the following script but the simple set servo1.set(duty) does not move the servo but the clock instruction does. I am sure it’s something obvious but I can’t see why it doesn’t work. Any suggestions greatly appreciated. The rc_test_servos -c 1 -p 1.5 bash script works on the servo.
bash script works
import rcpy import time import rcpy.clock as clock import rcpy.servo as servo from rcpy.servo import servo1 state = rcpy.get_state() print("state is ", state) run = rcpy.run() print("run is ", run) rcpy.idle() print("State is ", rcpy.get_state()) rcpy.run() print("State is ", rcpy.get_state()) servo.enable() duty = -1.5 # Send the servo to -1.5 print("Duty is ",duty) servo1.set(duty) time.sleep(2) # Send the servo to 1.5 duty =1.5 print("Duty is", duty) # Use period option to move the servo period =0.1 clk = clock.Clock(servo1, period) clk.start() time.sleep(2) print("Finish") servo.disable() rcpy.exit() print("Good bye")
