Conceptual and user-centric design guidelines for a plant nursing robot

Summary in the original language of the document

Current service robots have relatively primitive behaviours and limited interaction with the environment. Technological foresights have indicated that the next generation of service robots will demonstrate a high degree of autonomy and reliability, have minimal impact on the environment, and will interact in a flexible way with the user. It is necessary therefore, to determine the functional requirements for a future energy-efficient robotic bioproduction system from the perspective of various stakeholders, together with the development of a high-level framework for designing and prototyping the common functionalities of mobile robots. This study presents technical guidelines for the design of a plant nursing robot. The methodology uses Quality Function Deployment (QFD) functionalities involving the identification of relationships between identified user requirements and the derived design parameters. Extracted important user requirements included: 1) adjustable to row distance and parcel size, 2) profitable, 3) minimize damage to crops, and 4) reliable. Lower ratings were attributed to requirements such as: 1) affection value, prestige, 2) look attractive, 3) out of season operations, and 4) use of renewable energy. Subsequent important derived design parameters included: 1) PreparedForModularTools, 2) ControlableByExternalModules, 3) SemiAutonomous, and 4) Local- and GlobalPositioningSystem. The least important design parameters included: 1) OpenStandardSoftware, 2) Well-builtAppearance, 3) Wheels- With Infinite Steering Rotation, and 4) Internal Safety System. The study demonstrates the feasibility of applying a systematic design technique and procedures for translating the ‘consumer’s voice’ into the design and technical specifications of a robotic tool carrier to be used in bioproduction.
