Reflection:

Recently, the class “Robotics and coding” has started a new unit. We will make robot animals that will react to what we do. We learned to use the Microbit. It is a device that can be programmed to complete simple tasks such as turning a motor, detecting light, or, say, show a smile. The Microbit can be programmed online. We are supposed to use the microbit and its motors to create a moving animal (My motors work but the light sensors don’t). My animal is a turtle. It includes a head (detachable), a shell (the front can be opened), two front arms, and two back legs (or…maybe feet?). My code basically says that if a light=less (because the hand will block light when petting the turtle), the turtle’s head will look left and right (my servo still doesn’t work, although I can use my hand to conduct the currents from the Microbit to the “2”…This does work).

The turtle includes a flat shell (I didn’t have time to work out the dimensions of a round shell). Two arms stick out of the middle body part. They can move due to a thin layer of solidified hot glue. The arms are two layers thick while the legs are only one layer thick. If the Microbit is standing up (logo up), the 5×5 display will show a smiley face with eyes that look left and right. If the head is pressed hard enough, one of the buttons would be pressed. This would make the turtle’s arms move up and down.

I began to design the turtle by carving out an oval (24′ by 12′ (I Think ‘ means inch)). Next, I designed the 1 layer arm (*4). The top shell was actually broken into eight pieces as I thought there wouldn’t be enough cardboard left (there was). The Head was the last part to be designed.

One thing I learned about hydraulics is that water is better to use than air as it can not be compressed.

One piece of advice would be that they should make sure they have all they need as we had to change plans due to a lack of a properly sized spring.

my greatest success in this class was that I successfully made the launcher even though I had to change the plan.

Precious plastic recycles the plastic that is not used. Plastic is very bad for the environment. Most of the plastic is released into the oceans and moved into some of the garbage patches. Plastic causes a lot of deaths of fish and makes the surviving marine life unsafe to eat. Plastics also cause the ocean to become more acidic which make the water unsafe to drink.  My idea is to make a helmet using plastic. I began by searching up some helmets but most helmets have holes in them so they won’t work. Then, I decided to search for round helmets which are most commonly military helmets but when I asked the teacher, she said that there are no round molds so I decided to use a hexagonal mold, then I will cut the plastic so it will be round.
