Init Script

How would I write an init script that would allow me to set the min and max and speed before it moves a servo to its starting position?  I want to be able to have the robot move slowly when it initializes each servo.

I also want to be able to initialize each servo individually so I can keep the current draw to a minimum.    After the initialization is complete, I want to set the speed to a desired speed for each servo.

To create an initialization script that sets the minimum and maximum positions, as well as the speed for each servo before moving them to their starting positions, you can use the EZ-Script language in the Script skill. This script will ensure that each servo moves slowly during initialization to minimize current draw. After initialization, the script will set each servo to a desired speed for normal operations.

Here's an example of how you might write such an initialization script in EZ-Script:

# Define servo ports
$ServoPort1 = D0
$ServoPort2 = D1
# Add more servo ports as needed

# Define min and max positions for each servo
$MinPosition1 = 1
$MaxPosition1 = 180
$MinPosition2 = 1
$MaxPosition2 = 180
# Add more min and max positions as needed

# Define slow speed for initialization
$InitSpeed = 1

# Define desired speed for normal operations
$NormalSpeed = 5

# Set min and max positions for each servo
Servo.SetMinPositionLimit($ServoPort1, $MinPosition1)
Servo.SetMaxPositionLimit($ServoPort1, $MaxPosition1)
Servo.SetMinPositionLimit($ServoPort2, $MinPosition2)
Servo.SetMaxPositionLimit($ServoPort2, $MaxPosition2)
# Repeat for additional servos

# Set speed to slow for initialization
Servo.SetSpeed($ServoPort1, $InitSpeed)
Servo.SetSpeed($ServoPort2, $InitSpeed)
# Repeat for additional servos

# Move each servo to its starting position slowly
Servo.SetPosition($ServoPort1, ($MinPosition1 + $MaxPosition1) / 2) # Example starting position
Servo.SetPosition($ServoPort2, ($MinPosition2 + $MaxPosition2) / 2) # Example starting position
# Adjust starting positions as needed and repeat for additional servos

# Wait for servos to reach their starting positions
sleep(2000) # Adjust sleep duration as needed

# Set each servo to the desired speed for normal operations
Servo.SetSpeed($ServoPort1, $NormalSpeed)
Servo.SetSpeed($ServoPort2, $NormalSpeed)
# Repeat for additional servos

# Initialization complete, robot is ready for normal operations
print("Initialization complete")

This script sets the minimum and maximum positions for each servo, moves them to their starting positions at a slow speed to minimize current draw, and then sets each servo to a desired speed for normal operations. Adjust the servo ports, min/max positions, speeds, and starting positions as needed for your specific robot configuration.
