我试图通过改变速度来移动车辆.我已经能够在

Python中成功执行操作,但对于我的项目,我不能使用Python,所以我使用

Android来尝试进行相同的操作. Python中的工作功能是：

def send_ned_velocity(velocity_x, velocity_y, velocity_z):

"""

Move vehicle in direction based on specified velocity vectors.

"""

msg = vehicle.message_factory.set_position_target_local_ned_encode(

0, # time_boot_ms (not used)

0, 0, # target system, target component

mavutil.mavlink.MAV_FRAME_BODY_NED, # frame

0b0000111111000111, # type_mask (only speeds enabled)

0, 0, 0, # x, y, z positions (not used)

velocity_x, velocity_y, velocity_z, # x, y, z velocity in m/s

0, 0, 0, # x, y, z acceleration (not supported yet, ignored in GCS_Mavlink)

0, 0) # yaw, yaw_rate (not supported yet, ignored in GCS_Mavlink)

# send command to vehicle

vehicle.send_mavlink(msg)

vehicle.flush()

我想要做的是Android中的等效代码：

// Create the message

msg_local_position_ned msgMessageInterval = new msg_local_position_ned();

msgMessageInterval.x = 0;

msgMessageInterval.y = 0;

msgMessageInterval.z = 0;

msgMessageInterval.vx = 10;

msgMessageInterval.vy = 0;

msgMessageInterval.vz = 0;

msgMessageInterval.time_boot_ms = 0;

MavlinkMessageWrapper mavlinkMessageWrapper = new MavlinkMessageWrapper(msgMessageInterval);

// Send the message to MavLink

ExperimentalApi.getApi(drone).sendMavlinkMessage(mavlinkMessageWrapper);

// Listen for the message received

drone.addMavlinkObserver(new MavlinkObserver() {

@Override

public void onMavlinkMessageReceived(MavlinkMessageWrapper mavlinkMessageWrapper) {

System.out.println("MESSAGE RECEIVED="+mavlinkMessageWrapper.getMavLinkMessage().toString());

}

});

我错过了什么？任何帮助将不胜感激.

谢谢.
