 +**__Material selection__**
 +
 +The material selection for this workstation design was based on structural performance, durability, cost, and appearance. Each detail was selected for the functional and aesthetic requirements of an outdoor workstation. 
 +The foundation is a concrete base that has good stability and compressive strength. This ensures that the entire structure is well anchored in relation to the environment and can withstand environmental pressure like wind and uneven ground. The team then used wooden joists to construct wooden decking, which was chosen for its natural appearance and warm texture, with durable properties for a weathered and stable walking surface.
 +The table and benches- the seating surfaces are composed of **oak wood** for durability, exterior weather resistance, and appearance. The legs of each bench and the table are made of aluminium for its corrosion resistance and lightweight characteristics, which are required in the design of modular outdoor structures. One bench includes a back rest, which consists of oak wood slats supported by an aluminium frame on the top and bottom for rigidity and comfort.
 +
 +Another feature at the bottom of the structure is a custom **aluminium** footrest in a chargable, interesting, and atypical shape. The footrest contributes to user comfort, and adds to the overall appearance, by introducing a dynamic shape at the level of the ground.
 +The central structural column is made from **S355 structural steel**. While aluminium was initially considered for its lightness, S355 steel was ultimately chosen due to its superior strength and lower cost for structural applications.
 +
 +S355 steel provides the necessary load means for the central core to take the upper structures and the roof. The central structure has a cylindrical wooden form cover, the wooden form helps to provide warmth and softness visually, while also integrating the central core as part of the rest of the wood elements in the design.
 +The roof is also made from S355 steel to ensure it is able to safely support the loading of the photovoltaic system and retractable shade systems. The strength and stability of steel is important to manage wind load and the weight of the photovoltaic system.
 +
 +Lastly, at the nase of the central structure, a custom aluminium box is incorporated to hold electrical components like batteries, controllers, and other electronics. Aluminium is perfect for this purpose because of its properties such as corrosion resistance, machinability, and thermal properties, keeping sensitive components safe in an outdoor application.

 +The adjustable work surface is manually operated on the prototype.
  
 Some mechanical functionalities weren't implemented due to reflectivity with material paramaters and limitations of scaling. The automatic adjustment of benches and table surfaces, the team first intended to use a motor, however the limit of the prototype in scaling and mechanism access made this impossible. Leading to use of manual operation instead to simulate the intended adjustment capabilities. The smart control system is based on the ESP32 microcontroller which incorporates an OLED screen and built-in Wi-Fi module, as well as communication to TSL2561 luminosity sensor and HTU21D for temperature and humidity sensing and reproduction. Some mechanical functionalities weren't implemented due to reflectivity with material paramaters and limitations of scaling.

-//Provide here the conclusions of this chapter and make the bridge to the next chapter.//+ 
 +This chapter presented the overall development process of the Co-venient outdoor workstation, detailing its evolution from concept to practical implementation. Key activities undertaken in this process included defining design requirements, selecting material types and sources, structural and electrical design, packaging considerations, and creating a staged prototype that functioned. Specific consideration was given to incorporating sustainability, ergonomics, and user needs in every design decision. The smart control system, built using the ESP32 microcontroller platform was developed and examined to test responsive environmental sensing, automated lighting capability, and networking ability. Functional and software testing validated several of the anticipated use case scenarios, demonstrating both the feasibility and potential of the concept. The prototype served as a proof of concept that demonstrated how the final product would work in a real world application. The next chapter will provide a critical reflection on the project, including lessons learned and directions for future development.
