Surena-Mini is the first small-sized humanoid robot which is fabricated completely with 3D printing technology. Because of the flexibility of 3D printing technology, Surena-Mini can be assigned with both human proportions and aesthetic appeals. The choice of using 3D printed plastic parts for all mechanical components not only simplifies the mechanical design process and the manufacture of the robot, but also reduces the cost and the weight of Surena-Mini humanoid which are important characteristics in small-sized humanoid robots. Surena-Mini has a total of 23 degrees of freedom with a height of 53 [cm] and weight 3.3 [kg]. The main objective of Surena-Mini is to be a humanoid robotic platform for research and education purposes to accelerate academic research. Consequently, researchers can then focus only on the challenges in which they are interested. First of all, design concepts, specifications and mechanical design of Surena-Mini are presented. Furthermore, various experimental tests are investigated on fabricated robots in order to verify the performance of the implemented humanoid robot.

However, balancing the system's output (information presentation) and input (vehicle controls) has become a major challenge for automotive companies. To address the complexity and information overload, many have shifted from physical controls to embedded digital touchscreens, raising questions about how far this transition should go. This shift from physical to digital interfaces presents both benefits and drawbacks. On one hand, digital touchscreens can increase driver distraction due to the visual load and eliminate haptic feedback and muscle memory. On the other hand, they offer flexibility and modern aesthetics. The primary research question was: What are the pros and cons of physical and digital interfaces from a user perspective? The secondary question focused on how the context of use (driving vs. non-driving) impacts user experience with each interface type. To explore these questions, this thesis investigated user satisfaction with both physical controls and digital touchscreens. Online user interviews and a literature review were conducted to assess the pros and cons of each interface in different contexts. The findings revealed that no single interface type is universally preferred. Users favored physical controls while driving, due to the haptic feedback and ease of use, but preferred digital interfaces in non-driving situations, due to their modern appeal and functionality. The study also revealed that user preferences varied based on behavior and attitudes, with early adopters perceiving digital interfaces as more trendy, while conservative users viewed physical interfaces as more reliable. These insights led to the development of design guidelines and a hybrid interface concept, blending physical and digital elements. The concept was evaluated and deemed a better solution than existing systems, though some refinements were suggested. The results provide a foundation for balancing physical and digital elements in future IVI designs. The design guidelines, developed from user needs and research findings, aimed to balance the strengths of physical and digital interfaces. These guidelines led to a conceptual UI design that combined physical controls for driving tasks with digital touchscreens for flexibility in non-driving contexts. The hybrid design was evaluated by both original participants and a wider audience, receiving positive feedback as an improvement over current systems. However, some aspects, like balancing ease of use with digital complexity, needed refinement. Overall, the guidelines, impact map, and evaluations represent progress toward more intuitive and user-friendly in-vehicle interfaces
