This box is a rectangular container which will define the main geometry of the tendon module. It has an approximate width of 4 cm, depth of 5 cm and height of 3cm. These values are mainly determined by the LiPo battery size and the stacking of electronic components. Considering the tendon pulley and the tendon wire will require enough space to avoid tangling, this size of the box can be considered small for its intended usage. |

The interior configuration aims to have the LiPo battery on the bottom, the electronic parts on its top, and the DC gear motor on the level with the highlighted wall section shown on the right. This section has indents so that the motor holder part can easily slide through while holding the motor hanging on the wall. The tendon cable, which is attached to the pulley at the end of the motor shaft, goes through the hole on the wall which is located next to the motor holder hole. |

The remaining important features of the container are the power switch outlet and the lid placing indents. The highlighted rectangular hole on the lower part of the front wall is designed to let the power switch go through while keeping the rest of the electronics hidden behind the container walls. In order to avoid using screws to close the lid, two indents which are placed on the opposite side of a support column are placed as highlighted on the picture. These allow the lid to slide through the indents and stand securely on the support column. |
