Published methods of linear actuation via string transmission are discussed. A novel twisting string actuator design named Mini Twist is introduced. The design and components of the Mini Twist are thoroughly explained, and a theoretical model for its transmission method is discussed. The experimental set-up is defined. Experimental data regarding the relationship between string diameter, string tension, strand count, and strand type is presented, and analysis of the data is provided. The features of the actuator and the validity of the theoretical model are summarized.
