Hello, I've informed that MuJoCo is capable of simulating actuators upto 1st order dynamics with one actuator state. If necessary, would it be possible to increase the actuator system order to n-th order? To do so, I think I need to have access to a numerical integrator but it seems not. Do you have any plan to implement the feature? or could you guide me to customizing MuJoCo to implement that feature?
