rosmessage

ROS メッセージの作成

ページ内をすべて折りたたむ

構文

msg = rosmessage(messagetype)

msg = rosmessage(pub)

msg = rosmessage(sub)

msg = rosmessage(client)

msg = rosmessage(server)

msg = rosmessage(___,"DataFormat","struct")

説明

msg = rosmessage(messagetype) は、メッセージタイプをもつ空の ROS メッセージオブジェクトを作成します。messagetype string スカラーでは、大文字と小文字が区別され、部分一致は受け入れられません。rosmsg list を呼び出すことで与えられたリスト上のメッセージと一致していなければなりません。メッセージタイプがリストにない場合は、rosgenmsg 関数を使用して追加します。

メモ

将来のリリースでは、ROS Toolbox は ROS メッセージ用のオブジェクトではなくメッセージ構造体を使用します。

現時点でメッセージ構造体を使用する場合、名前と値の引数 "DataFormat" を "struct" に設定します。詳細については、ROS メッセージ構造体を参照してください。

例

msg = rosmessage(pub) は、pub によってパブリッシュされたトピックで決定される空白のメッセージを作成します。

例

msg = rosmessage(sub) は、sub のサブスクライブされるトピックで決定される空白のメッセージを作成します。

msg = rosmessage(client) は、client のサービスタイプまたはアクションタイプで決定される空白のメッセージを作成します。

msg = rosmessage(server) は、server のサービスタイプまたはアクションタイプで決定される空白のメッセージを作成します。

msg = rosmessage(___,"DataFormat","struct") は、前述の構文にある任意の引数を指定して、空のメッセージをメッセージ構造体として作成します。詳細については、ROS メッセージ構造体を参照してください。

空の string メッセージの作成

ライブスクリプトを開く

ROS メッセージを std_msgs/String メッセージタイプの構造体として作成します。

strMsg = rosmessage("std_msgs/String","DataFormat","struct")

strMsg = struct with fields:
    MessageType: 'std_msgs/String'
           Data: ''

ROS パブリッシャーを作成してデータを送信

ライブスクリプトを開く

ROS メッセージの配列の作成とアクセス

ライブスクリプトを開く

複数のメッセージを保存する構造体配列を作成できます。配列は他の配列と同様にインデックス可能です。各オブジェクトのプロパティを変更するか、ドット表記を使って各要素から特定のプロパティにアクセスすることができます。

2 つのメッセージの配列を作成します。名前と値の引数 DataFormat を指定して、ROS メッセージ構造体を使用します。

blankMsg = rosmessage("std_msgs/String","DataFormat","struct")

blankMsg = struct with fields:
    MessageType: 'std_msgs/String'
           Data: ''

msgArray = [blankMsg blankMsg]

msgArray=1×2 struct array with fields:
    MessageType
    Data

データを配列の個々のメッセージフィールドに代入します。

msgArray(1).Data = 'Some string'; 
msgArray(2).Data = 'Other string';

メッセージのすべての Data フィールドを cell 配列に読み取ります。

allData = {msgArray.Data}

allData = 1×2 cell
    {'Some string'}    {'Other string'}

ROS メッセージ配列の事前割り当て

ライブスクリプトを開く

ROS メッセージをオブジェクトとして使用して配列に事前割り当てを行うには、関数 repmat の代わりに関数 arrayfun または cellfun を使用します。これらの関数は、ハンドルクラスのオブジェクトまたは cell 配列を正しく作成します。

メモ: 将来のリリースでは、ROS メッセージオブジェクトは削除されます。ROS メッセージを構造体として使用し、構造体配列を利用するには、関数 rosmessage を呼び出すときに名前と値のペア DataFormat を指定します。

ROS メッセージのオブジェクト配列に事前割り当てを行います。

msgArray = arrayfun(@(~) rosmessage("std_msgs/String"),zeros(1,50));

ROS メッセージの cell 配列に事前割り当てを行います。

msgCell = cellfun(@(~) rosmessage("std_msgs/String"),cell(1,50),"UniformOutput",false);

入力引数

すべて折りたたむ

`messagetype` — メッセージタイプ
string スカラー | 文字ベクトル

メッセージタイプ。string スカラーまたは文字ベクトルとして指定します。string は大文字と小文字が区別され、部分一致は受け入れられません。rosmsg("list") を呼び出すことで与えられたリスト上のメッセージと一致していなければなりません。

`pub` — ROS パブリッシャー
`Publisher` オブジェクトハンドル

ROS パブリッシャー。Publisher オブジェクトハンドルとして指定します。rospublisher を使用してオブジェクトを作成できます。

`sub` — ROS サブスクライバー
`Subscriber` オブジェクトハンドル

ROS サブスクライバー。Subscriber オブジェクトハンドルとして指定します。rossubscriber を使用してオブジェクトを作成できます。

`client` — ROS サービスクライアントまたはアクションクライアント
`ServiceClient` オブジェクトハンドル | `ActionClient` オブジェクトハンドル

ROS サービスクライアントまたはアクションクライアント。ServiceClient または ActionClient オブジェクトハンドルとして指定します。それぞれ rossvcclient またはrosactionclient を使用して、サービスクライアントオブジェクトまたはアクションクライアントオブジェクトを作成できます。

`server` — ROS サービスサーバーまたはアクションサーバー
`ServiceServer` オブジェクトハンドル | `ActionServer` オブジェクトハンドル

ROS サービスサーバーまたはアクションサーバー。ServiceServer または ActionServer オブジェクトハンドルとして指定します。それぞれ rossvcserver またはrosactionserver を使用して、サービスサーバーオブジェクトまたはアクションサーバーオブジェクトを作成できます。

出力引数

すべて折りたたむ

`msg` — ROS メッセージ
`Message` オブジェクトハンドル | 構造体

ROS メッセージ。Message オブジェクトハンドルまたは構造体として返されます。

拡張機能

すべて展開する

C/C++ コード生成
MATLAB® Coder™ を使用して C および C++ コードを生成します。

使用上の注意および制限:

struct メッセージでのみサポートされます。
sensor_msgs/JointState のように string の cell 配列を含むフィールドがあるメッセージについては、MATLAB 関数でこれらのフィールドにアクセスすることはサポートされていません。

R2021a: ROS メッセージ構造体

これで、メッセージオブジェクトのプロパティと一致するフィールドをもつ構造体としてメッセージを作成できます。通常、構造体を利用すると ROS メッセージの作成、更新、使用のパフォーマンスが向上しますが、設定時にメッセージのフィールドが検証されなくなります。メッセージタイプと、構造体から取得した対応するフィールド値は、ネットワーク経由で送信されたときに検証されます。

ROS メッセージを構造体として使用するには、パブリッシャー、サブスクライバー、またはその他の ROS オブジェクトの作成時に名前と値の引数 "DataFormat" を使用します。これらのオブジェクトから生成されたすべてのメッセージで構造体が利用されます。

pub = rospublisher("/scan","sensor_msgs/LaserScan","DataFormat","struct")
msg = rosmessage(pub)

また、メッセージを直接構造体として作成することもできますが、パブリッシャー、サブスクライバー、またはその他の ROS オブジェクトについても必ずデータ形式を "struct" として指定してください。現時点では、ROS オブジェクトは既定でメッセージオブジェクトを使用します。

msg = rosmessage("/scan","sensor_msgs/LaserScan","DataFormat","struct")
...
pub = rospublisher("/scan","sensor_msgs/LaserScan","DataFormat","struct")

将来のリリースでは、ROS メッセージは既定で構造体を使用し、ROS メッセージオブジェクトは削除されます。

詳細については、Improve Performance of ROS Using Message Structuresを参照してください。
