無人航空機(UAV、ドローン)は、手のひらサイズの小型ドローンから、相当重い積荷を運んだり、娯楽や防犯用に静止画や動画を撮影したりできる業務用ドローンまで、設計上の用途に応じてさまざまな規模のものがあります。

ドローン設計における最大の課題は、飛行時間と積載重量の目標を満たすことです。このためには、プロペラ数、バッテリ容量、重量、センシング機能や通信機能に関して最善のバランスを考慮した機械・電子設計が必須です。

そこで重要になるのが内蔵電子機器です。この内蔵電子機器は通常、飛行制御ユニット(FCU)、プロペラを駆動する電子速度コントローラ(ESC)、搭載カメラ、およびジンバル制御に分けられます。

STは、ESCおよびジンバル制御用のモータ制御ソリューションや高性能なFCU設計を提供しています。STの製品ポートフォリオは、パワーMOSFET、モノリシック・モータ・ドライバ、高性能マイクロコントローラSTM32に加えて、各種モーション / 環境 / 測距センサ、通信ソリューション、すぐに使用可能なリファレンス・デザイン・ボードまで幅広く含み、対象アプリケーションに最適な飛行性能を備えたドローンの開発をサポートしています。
