Roli H-Bridge Question Too

Did you set the pwm speed?

Modifying the project did you accidentally miss the speed initialization script for the hbridge in the connection control?

here is the init script :

# This is the initialization script for your Roli robot
# This script is called from the Connection Control when a connection
# is made to the Roli EZ-B

# Move the servos into the calibration position
# All servos will be set to 90 degrees
ControlCommand("Auto Position", AutoPositionFrameJump, "Calibrate")

# Pause for a brief period of time to ensure the servos have been initialized
sleep(500)

# We want the arm and neck servos to move smoothly
# To do this, we will set the speed of each servo
# The speed is how quickly a servo will move between positions
# We set a variable for the speed, and then use that variable for
# every speed command.
# This is an effecient way to reuse a value numerous times
$speed = 1

servospeed(d12, $speed)
servospeed(d13, $speed)
servospeed(d14, $speed)
servospeed(d15, $speed)
servospeed(d16, $speed)
servospeed(d17, $speed)
servospeed(d18, $speed)
servospeed(d19, $speed)

# This sets the speed for the HBridge Motor Controller
# The speed is a number between 0 and 255
# Setting this speed will initialize the PWM on the motor controller
SetSpeed(255)

# Even though we set the speed, we will also enable the PWM
# on the speed pins that connect to the HBridge Motor Controller
# The number is 100, which means 100%
pwm(d0, 100)
pwm(d5, 100)

Hello,

Sorry, I did not have time to see my problem.

Maybe I could during the Christmas holiday;)
