This bachelor thesis focuses on the design of a contactless control system for a robotic ultrasonic diagnostic workstation using hand gestures. The motivation is to create a more natural form of interaction between the operator and the robot, reducing the need for physical control devices and supporting smoother operation in an industrial environment. The proposed solution uses the MediaPipe library for hand landmark extraction and a TemporalConvBiLSTM model for dynamic gesture classification. A custom set of seven gestures was created according to the movement and functional requirements of robotic ultrasonic diagnostics. The model was evaluated using the TRUE LOSO strategy and achieved a global accuracy of 96.64 %. Real-time testing confirmed the practical usability of the proposed system, achieving an accuracy of 94.90 % under daylight conditions.
