-Every project needed to be planned carefully because a project plan gave an overview of all the tasks and deliverables that needed to be completed. Having a good project plan and following it well allowed the smooth running of the project, and kept the project running on schedule. Table {{ref>tpjctpn}} shows the planning used for this project. In [[report#time|Chapter 3.3]] there is a comprehensive project plan including a Gantt chart.+Every project needed to be planned carefully because a project plan gives an overview of all the tasks and deliverables that need to be completed.

 To begin with the architecture of the prototype, a cardboard model was made as a first approach to find out the optimal dimensions and opening system of the "EscarGO" that did not require an extra amount of free space around for its movement. The Team also used it to show the curtain system. It can be seen in Figures {{ref>fcard1}}, {{ref>fcard2}} and {{ref>fcard3}}. To begin with the architecture of the prototype, a cardboard model was made as a first approach to find out the optimal dimensions and opening system of the "EscarGO" that did not require an extra amount of free space around for its movement.

 The Team had to do some brainstorming in order to fix the flaws found in the first design. The original pivoting opening system was not very likely to be long lasting, and therefore unsustainable. In order to keep the cover removal simple, the group decided not to host the technologies inside the cover and add a chamfer instead for that purpose. These changes in the product (see Figure {{ref>ffinal}}) were intended to make the "EscarGO" more user friendly. The Team had to do some brainstorming in order to fix the flaws found in the first design.

 In this sub-section, the final 3D model is shown. The Team decided to use another technique for opening the terrarium instead of the pivoting system. The dimensions of the "EscarGO" would be 400 mm x 300 mm x 375 mm. Figure {{ref>f3d2}} shows an overview of the whole product. In this sub-section, the final 3D model is shown.

 Another addition that the Team considered is adding controls so that the humidity and temperature can be changed to suit different insects or reptiles. Controls for the time function, such as a real-time clock, would also be included in the final product, but for the prototype the Team was limited by cost so these details couldn't be added. Another addition that the Team considered is adding controls so that the humidity and temperature can be changed to suit different insects or reptiles.

-In the prototype, there is a water tank included to keep the soil moist. The team did some tests with poly-acrylate and microspheres. The microspheres are an improved solution compared with the water tank so for the future the Team wants to include the microspheres in addition to the water tank. These are not harmful for the snails and the family can make those Microspheres together to make the family bond stronger.+In the prototype, there is a water tank included to keep the soil moist.

This was necessary because they need to live in the "EscarGO". The team did not have time to test the prototype with the snails because to monitor the growth and quality of life of the snails would require a minimum of 3 months of living within "EscarGo".
