Expose Telemetry Data

[joel-mb]

Description

This PR exposes the telemetry data to the client:

vehicle.get_telemetry_data()

This will return a VehicleTelemetryData structure with the following information

VehicleTelemetryData(
    speed  # [m/s]
    steer
    throttle
    brake
    engine_rpm
    gear
    drag  # [N]
    wheels  # list of WheelTelemetryData
)
WheelTelemetryData(
    tire_friction
    lat_slip  # [degrees]
    long_slip
    omega
    tire_load
    normalized_tire_load,
    torque  # [Nm]
    long_force  # [N]
    lat_force  # [N]
    normalized_long_force
    normalized_lat_force
)

Where has this been tested?

• Platform(s): Ubuntu 18.04
• Python version(s): 3.7
• Unreal Engine version(s): 4.26

Hi, I was able to implement this code for my project & I'm able to use the command

telemetry = world.player.get_telemetry_data

Inside this, I get a structure like you've mentioned & I can access the VehicleTelemetryData using operator. But when I try to get the WheelTelemetryData using telemetry.wheels (I'm a noob, I know), I get an error:

TypeError: No to_python (by-value) converter found for C++ type: class std::vector<class carla::rpc::WheelTelemetryData,class std::allocator<class carla::rpc::WheelTelemetryData> >

Can you help me with this issue?

Hi, is there a plan to merge this PR to dev? The telemetry info exposed here to the client is pretty useful.

Thanks in advance,
Akshay
