I am trying to run Jmavsim in HITL mode. I follwed the link
https://pixhawk.org/dev/hil/jmavsim
and used /dev/ttyACM0(Pixhawk connected through usb(serial)) and /dev/ttyUSB0(Pixhawk connected through radio telemetry(udp)) and as mention in link ttyusbmodem1 but every time it throws serial port exception either port not found or port busy.
Thanks.
I am trying to communicate to vagrant through udp , but I get the below message:

How much work is actually needed to change it into fully-working SITL for Pixhawk (or ArduPilotMega?)
I am really looking forward finding an alternative for heavy Gazeboo simulator.
What do you think needs to be done and what are barriers?
it looks like rc should be 1/tau but it is set to 1/(2 pi tau)
Also, tau = 5msec seems far too small a delay to model realistic ESC/motor/prop impulse response.
I installed Cygwin v2.3.0, Apache Ant v1.9.6 and Java JDK v1.8.0u66 (8 Update 66) on Windows 10.
Ran git clone git://github.com/DrTon/jMAVSim
.
Then changed
serialMAVLinkPort.open("/dev/tty.usbmodem1", 230400, 8, 1, 0);
to
serialMAVLinkPort.open("COM3", 115200, 8, 1, 0);
(I will use it with APM) in Simulator.java
Then ran:
cd jMAVSim
git submodule init
git submodule update
Then compiled it, ran ant
.
Then ran the jar file with:
java -Djava.ext.dirs= -cp lib/*;out/production/jmavsim.jar me.drton.jmavsim.Simulator
And got this error, any idea why?

I've a px4 working with JmavSim.
I've understood that I can connect using udp port ( 14556 ) only before this error
ERROR [Unknown] WARNING! TIME IS NEGATIVE! 16203872 vs 16203873
(each time, the time value changes)
When I get this error the comunication with my virtual drone stops.
What is this error ?
How can I solve ?
it happens every time after few minutes or seconds
Hi,
I have an issue when I start jMAVSim to communicate with px4 by running:
java -Djava.ext.dirs= -cp lib/*:out/production/jmavsim.jar me.drton.jmavsim.Simulator -serial /dev/ttyACM0 921600 -qgc
it shows the blow log:
WARNING: Got heartbeat from system #2 but configured to only accept messages from system #1. Please change the system ID parameter to match in order to use HITL/SITL.
is that related to MAV_SYS_ID?
Every time i start simulator i should wait almost minute, only after that time it writes
Init MAVLink
and other messages and i am able to flight.
Hello group members,
I am trying to carry the flight simulation in jMAVSim using Pixhawk controller,
but i have some problem
I want to hexacopter simulation in jMAVSim and edited the 'Simulator.java'
There is a hexacopter code in vehicle folder, and i applied in Simulator.java source code.
But when i shoot the flight simulation in jmavsim, it cannot maneuver well
(altitude change works, but heading change does not work)
did i miss some steps ?
I didnot changed anything in QGC (including frame setting as 'HIL quadroter x')
Actually it worked well w/ the quadcopter code
The only thing i have changed is the Simulator.java code
If someone has some clue for this, I really appreciate it
Thank you :)
ps. Firmware PX4 1.4.4 is used
Hello all,
Im using the qgroundcontrol (version 2.9) and update the firmware, then disconnect, then open up jMAVSim. Up to this point, from the terminal I can see the following:
Init MAVLink
MSG: [inav] GPS timeout
MSG: [inav] GPS signal found
After that, Im trying to turn off the safety switch to enable the motor on my drone (IRIS 3DR), but no respond. I also tried to disarm it from my RC, but also no respond.
Im using Ubuntu 14.04
The lines I used to run jMAVSIM were:
Any help will be appreciated! Thanks!
I use the pixhawk, and connect via USB (/dev/ACM0), and then the jMAVLink can't dispaly the status, just on the ground,
and i try to connect the QGC via udp, the QGC display No Rules.
Thanks.
Hi.
I'm trying to use your simulator, but I'm getting this error when I run mavros (rosrun mavros px4.launch). On mavros I get one heartbeat, and then mavros looses connection with the simulator.
Can you help me?

HI
Can someone please guide me how can I get two vehicles on qgroundcontrol using jMAVSim?
Currently jMAVSim is simulating a single vehicle on qgroundcontrol. WHat I want is simulating two vehicles using a single jMAVSim simulator. Can anyone please guide me how can I proceed with this issue?

Omar
Hi,
I have a working Matlab Simulink model of a Quadcopter and would like to connect it to the HITL Simulation of PX4. My plan is to modify the jMAVSim in a way that instead of calculationg all the Forces etc. whithin the jMAVSim it actually calculates them in Simulink and passes (using UDP) the information to the jMAVSim (which will still handel all of the MAVLink communication with PX4).
Can you tell me where exactly in the code of jMAVSim are you calculating the accelerations, forces etc. of the copter and where does the desired signal of the PX4 act on the system?
Would be great if you could help me!
regards
Dominik

I'm trying to compile jMAVSim for the first time.
Some mismatch with arguments/return values to/from MAVLinkStream in jMAVLib.
Constructor, read and write methods seem to be affected
Hi Anton, is there anyreason why you chose to use Java3d? It seems like it is on it's way out, I was considering trying to convert your source code to Opengraphscene/C++. Would you be availible for questions while I was attempting this undertaking? Thanks
I'm getting an odd error with jmavsim, but only when running remotely using x11 forwarding. Any suggestions much appreciated.

Hi!
I am trying to simulate a Dodecarotor Cox multicopter. I started my mod from your hexacopter vehicle, and followed the numbering so that it matches the PX4 - QGC numbering found here (https://docs.px4.io/master/en/airframes/airframe_reference.html).
Dodecarotor.java:
package me.drton.jmavsim.vehicle;
import me.drton.jmavsim.Rotor;
import me.drton.jmavsim.World;
import javax.vecmath.Matrix3d;
import javax.vecmath.Vector3d;
/**
Generic Dodecarotor model.
*/
public class Dodecarotor extends AbstractMulticopter {
private static final int rotorsNum = 12;
private Vector3d[] rotorPositions = new Vector3d[rotorsNum];
// private int[] rotorRotations = new int[rotorsNum];
/**
Generic Dodecarotor constructor.
@param world world where to place the vehicle
@param modelName filename of model to load, in .obj format
@param orientation "x" or "+"
@param armLength length of arm from center (m)
@param rotorThrust full thrust of one rotor (N)
@param rotorTorque torque at full thrust of one rotor (Nm)
@param rotorTimeConst spin-up time of rotor
@param rotorHeight height of propeller from center point (m)
@param rotorsOffset rotors positions offset from gravity center
@param showGui false if the GUI has been disabled
*/
public Dodecarotor(World world, String modelName, String orientation, double armLength,
double rotorThrust, double rotorTorque, double rotorTimeConst, double rotorHeight,
Vector3d rotorsOffset, boolean showGui) {
super(world, modelName, showGui);
rotorPositions[0] = new Vector3d(0.0, armLength, -rotorHeight);
rotorPositions[1] = new Vector3d(0.0,-armLength, -rotorHeight);
rotorPositions[2] = new Vector3d(armLength * Math.sin(Math.PI / 3),
-armLength * Math.cos(Math.PI / 3), -rotorHeight);
rotorPositions[3] = new Vector3d(-armLength * Math.sin(Math.PI / 3),
armLength * Math.cos(Math.PI / 3), -rotorHeight);
rotorPositions[4] = new Vector3d(armLength * Math.sin(Math.PI / 3),
armLength * Math.cos(Math.PI / 3), -rotorHeight);
rotorPositions[5] = new Vector3d(-armLength * Math.sin(Math.PI / 3),
-armLength * Math.cos(Math.PI / 3), -rotorHeight);
rotorPositions[6] = new Vector3d(0.0, armLength, rotorHeight);
rotorPositions[7] = new Vector3d(0.0,-armLength, rotorHeight);
rotorPositions[8] = new Vector3d(armLength * Math.sin(Math.PI / 3),
-armLength * Math.cos(Math.PI / 3), rotorHeight);
rotorPositions[9] = new Vector3d(-armLength * Math.sin(Math.PI / 3),
armLength * Math.cos(Math.PI / 3), rotorHeight);
rotorPositions[10] = new Vector3d(armLength * Math.sin(Math.PI / 3),
armLength * Math.cos(Math.PI / 3), rotorHeight);
rotorPositions[11] = new Vector3d(-armLength * Math.sin(Math.PI / 3),
-armLength * Math.cos(Math.PI / 3), rotorHeight);
if (orientation.equals("x") || orientation.equals("X")) {
Matrix3d r = new Matrix3d();
r.rotZ(-Math.PI / 2);
for (int i = 0; i < rotorsNum; i++) {
r.transform(rotorPositions[i]);
}
} else {
throw new RuntimeException("Unknown orientation: " + orientation);
}
for (int i = 0; i < rotors.length; i++) {
rotorPositions[i].add(rotorsOffset);
Rotor rotor = rotors[i];
rotor.setFullThrust((i > 5) ? 0.9*rotorThrust : rotorThrust); //Lower propeller reduced efficiency
rotor.setFullTorque((i == 6 || i == 3 || i == 4 || i == 6 || i == 8 || i == 11) ? -rotorTorque : rotorTorque);
rotor.setTimeConstant(rotorTimeConst);
}
}
@OverRide
protected int getRotorsNum() {
return rotorsNum;
}
@OverRide
protected Vector3d getRotorPosition(int i) {
return rotorPositions[i];
}
}
I am calling it from Simulator.java using these specific values :
private AbstractMulticopter buildMulticopter() {
Vector3d gc = new Vector3d(0.0, 0.0, 0.0); // gravity center
AbstractMulticopter vehicle = new Dodecarotor(world, DEFAULT_VEHICLE_MODEL, "x",
0.6096, 306.26, 19.07, 0.005, 0.114, gc, SHOW_GUI);
Matrix3d I = new Matrix3d();
// Moments of inertia
I.m00 = 39.0; // X
I.m11 = 39.0; // Y
I.m22 = 52.0; // Z
vehicle.setMomentOfInertia(I);
vehicle.setMass(100);
vehicle.setDragMove(2);
SimpleSensors sensors = new SimpleSensors();
sensors.setGPSInterval(50);
sensors.setGPSDelay(200);
sensors.setNoise_Acc(0.05f);
sensors.setNoise_Gyo(0.01f);
sensors.setNoise_Mag(0.005f);
sensors.setNoise_Prs(0.1f);
vehicle.setSensors(sensors, getSimMillis());
//v.setDragRotate(0.1);
return vehicle;
}
The build of the code is successful, however, my drone does not take off. I believe the error might lies in AbstractMulticopter.java . Can you help me? Or is there resources anywhere to help me build my own airframe configurations?
Is there anyreason why I got a warning
MSG: [inav] GPS timeout
or
MSG: [inav] init ref: 55.7533950, 37.6254270, 0.0000
MSG: home: 55.7533950, 37.6254270, -0.01
then
(MAV 001:50) [inav] GPS signal found
(MAV 001:50) [inav] GPS signal lost
these two warnings when I started jMAVsim and keep warning all the time even though I armed the plane with RC.
My setting up are
I tried both RC_MAP_OFFB_SW = 8
and rosrun mavros mavsys mode -c OFFBOARD
method, but still got
(MAV 001:50) REJECT OFFBOARD
I checked the ros topic /mavros/setpoint/local_position
worked fine but only send (0, 0, 3) for climbing.
My setting up are
./setpoint_demo.py
as mentioned at https://pixhawk.org/dev/ros/hil.Hi all,
This is definitely a great piece of work. However for non-Java user the usage is unclear. Could anyone give some instructions?
How can we simulate multiple vehicles communicating with jMAVSim via MAVLink messages?
I am able to download and compile the jMAVSim directory using ANT. When I run "java -Djava.ext.dirs= -cp lib/*:out/production/jmavsim.jar me.drton.jmavsim.Simulator -udp 127.0.0.1:14560" I get the error could not find or load main class me.drton.jmavsim.Simulator. Am I not doing something correctly with the build.xml file? Is there something else that I am missing here?
Thanks,
I'm trying to connect qgroundcontrol with jMAVSim as specified in
http://pixhawk.org/dev/hil/jmavsim but clicking on the connect button does not work.
Also tried with APMPlaner and has the same problem.
These are impulse response models constructed from log data collected using MatrixPilot firmware in an AeroQuad frame. 3S battery, 1000KV 2212 motors, 10x4.7 props, 680mm between motor centers.
The Pitch moment of inertia is a little higher than the Roll moment.
Impulse response model: A exp(-t/tau) sin(omega t)
Delay values in plot headers are the estimated command->response latency for thrust and rotation rate, respectively.
This plot is for a HobbyKing microQuad with motor spacing of 220mm:
How does jMAVSim perform IRIS simulation with qgroundcontrol? Does jMAVSim has a build-in IRIS dynamic model or get the model from somewhere else?
It seems to me that the default modeling parameters in Simulator.java is quite different to IRIS specs.
Hello I am getting a compile error this file seem to be missing in the master:
me.drton.jmavlib.geo
Hi all,
I found that I could't adjust the way to view the quadcopter in jMAVSim, any idea to change it?
Thanks in advance!

Hey there!
Just curious if you had ever considered creating a headless version of the simulator. It looks like Java3d is tightly coupled though.
This is my first time using any of these. Please tell me if I did anything wrong.
I started jMAVSim using
sudo java -cp lib/*:out/production/jmavsim.jar me.drton.jmavsim.Simulator
Then, I connected the quad. I run
roslaunch mavros px4.launch
Then I armed it by
rosrun mavros mavsafety arm
I pressed the safety switch and armed it. Then I run the ./setpoint_position_demo.py from https://pixhawk.org/dev/offboard_control/testing
Then, I change it to Offboard mode using
rosrun mavros mavsys mode -c OFFBOARD
There was no change in the simulator window. The output of the jMAVSim Terminal is
3D [dev] 1.6.0-pre12-daily-experimental daily

Hi,
I'm trying to get jMAVSim to work with PX4FMU, PX4 flight stack. I was able to get jMAVSim running and connected to PX4 via USB. I can also connect with qgroundcontrol to jMAVSim via UDP successfully.
The problem is, jMAVSim only receives mode changes, but nothing happens in simulator window (motors also don't spin).
Here is what's printed in console of jMAVSim:
$ java -Djava.library.path=./ -cp out/production/jmavsim.jar me.drton.jmavsim.Simulator
Init MAVLink
MSG: Switched to ON hil state
MSG: detected RC signal first time

Maybe I am missing some obvious configuration steps and this is not a bug, but an error on my side?
I would also welcome any tips on how to debug this issue.
