You can load the roli project and view the init script. Here is the init script as of today (2016/04/14):

Code:

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
Set the max and min positions of some servos so
they cannot move past their limitations
Left Gripper
SetServoMin(d16, 30)
SetServoMax(d16, 90)
Right Gripper
SetServoMin(d12, 30)
SetServoMax(d12, 90)
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)
This sets up variables for use within the mobile interface
as a toggle for using the sliders for movement and to keep
of the direction currently moving
$DirectionMobile=""

yes i now that.i want to let go the servo slower a start up. so do i need to set the speed to 4 instead or $speed ?

i want the arms and head/neck go slower

think i have it

servospeed(D12,$speed=4)

$speed is a variable, it holds values. Change the value that is assigned to $speed

Code:

$speed = 4

The description of $speed is right there in the code. The code has a big chunk that explains $speed is a variable. Read the descriptions in the code, it will help make sense.

okay dj thanks

1 is fast and 4 is slower
