About ScriptController parameter model

[Wei Wang]

Hi,

We revised 0914 model with an ideal ankle actuator called <CoordinateActuator name="Ankle_Exoskeleton_r">.

Then we want to use it in the ScriptController by command :
target_actuator = model:find_actuator("Ankle_Exoskeleton_r")

but an error shows that "Could not find 'Ankle_Exoskeleton_r'".

How can i solve this problem?

Thanks!

If I am correct you can find the actuator just by using the actuated dof's name, thus:

target_actuator = model:find_actuator("ankle_r")

Another way to check which actuators are present, you can loop over the actuators in a lua script and display the names

Code: Select all

	scone.debug("\nActuators:")
	for i = 1, model:actuator_count(), 1 do
		scone.debug(model:actuator(i):name())
	end

which could be in a ScriptController file for instance:

Code: Select all

function init(model, par)

	scone.debug("\nActuators:")
	for i = 1, model:actuator_count(), 1 do
		scone.debug(model:actuator(i):name())
	end
	
end

function update(model)
	t = model:time()
	return false
end

The output with the names will show up in the console of SCONE

You are correct! It's ok now.

Thank you very much for the answer and suggestion!
