     For the work period of September 10th-23rd, Team 8 has successfully acquired the required materials for the connecting parts. The materials have been delivered to the UH machinist where the fabrication process has been scheduled for October 1st-October13. Additionally, the team has made slight design decisions to the intermediate connecting part, due to budget constraints. Instead of utilizing a 1.10inch thick aluminum plate to construct the intermediate connecting part, the team has instead opted for an aftermarket "hat channel" composed of fiberglass. The fiberglass component can be seen in Figure 1 below. Its dimensions are similar to those of our initially designed aluminum component, with a width reduction of 2 inches, length reduction of 3 inches, and thickness reduction of  1/4''.  Figure 1: Fiberglass Intermediate Connecting Part Furthermore, the team has also made progression with the validation plan of the project. To further analyze the performan...

       Over the work period of August 21- September 9, Team 8 has finished the f itment testing of the required parts as well as the system motion testing. The fitment assembly was completed by a combination of 3D printed components and cardboard made components as shown in the figures below. Fig. 1 Seat and Seat Frame Fig.2 Intermediate Connecting Part As observed in the images above the H support and top intermediate connecting part were 3D printed, whereas the seat and seat frame were made out of card-board.  All components were made following the real measurements from the Solid works model. A final assembly is shown below, where each prototype part has been temporarily fixated to its corresponding location. Figure 3 shows the "neutral" sitting position of the Wheelchair Lifting Aid, and Figure 4 shows the seat with the fully extended linear actuator.  Figure 3: Neutral Position of Wheelchair Lifting Aid Figure 4: Final seat position of Wheelchair Lifti...
