2. Final project design
I started with the design of load cell. Since the structure will revolve around it, I am using SolidWorks multibody method to make the process seamless.
I then designed (metal) frame around the load cell.
Since the top and bottom frame must not touch each other, however it is not necessary to keep them far apart. Therefore, I reduced the distance between the. I used move mody method.
At the bottom frame, I extended it by adding a frame to support the vertical stand.
I then added vertical stand of 2.1m.
Since this stand is tall, I splitted it into 3 sections. This not only easy the assembly, it also ease its packaging and transportation
I then added support structure inside. This will also guide me during assembly.
I then added cutout for screen as well as that of Ultrasonic Sensor
