05/07: Today we obtained more printed 3D parts and are now ready to start assembling some of them. However a crucial part we need to assemble them are M8 screws that are not available on accessible platforms such as shopee or Lazada. However we were able to find them in Jurong Point (Shout out to Kim Able Hardware Store) that have M8 screws in varying length.  We also decided to remove all use of brass inserts in our parts, and instead opt for a small gap in our models to insert a nut, for the screw to be secured in.

7/8: Soldering of PCA9685 and test soldering of the PCB was done! Some small changes was also made towards the 3D design of the seed disperser that was some problem with attaching the different parts during assembly.

Left: Combine the orange round part and black part, leave the hole for the middle m5 screw and change the screw hole size to M1 instead to fit metal servo motor coupler

Middle: The M3 screws initially used to secure the top and bottom piece together is not long enough (longest they have is M3x40). We needed to create a gap in the middle of this bottom red piece for us to insert the nut to hold the pieces together with a screw +Please combine the red top piece and green tubing together

Right: Create a hole on the black piece for us to put a screw and combine the green part together by putting a gap on the middle to insert a insert to secure the screw to

8~11/8: Use of Canva to do our A1 Poster: Including Title, Introduction, Function of & how different part works, as well as future opportunities & improvements. As space was limited, we have to pick and only include vital information and images in our poster. We decided to allocate the most space into the physical parts of the rocker bogie as it is the core of our idea.

2 & 3/8: Receive of PCB and soldering of it was done. 3D designing and printing of motor + servo housing to give it more support and make it longer so that it can navigate over rockier terrains. All of the motor was wired up and attached to PCB, and is able to run!

4/8: The hinge used to connect the legs have too much rotational force on it due to the compression on the metal hinge which causes the legs to bent in an outward angle when the wheels are rotating. We tried to use spacers such as nuts and washers to reduce the compression but it was ineffective. As such, further exploration on the types of hinges are available needs to be done to remove or reduce the rotational force.
