In our recitation 4, we’re required to build a mechanism out of cardboard. I’m in a group with Joy Yang, at first we decide to divide our work, I set the code and build the circuit while she use cardboard to complete the part of the handmade shell， then we worked together to put the actuators provided into the shell and connected them with my circuit and the computer which was protected by the USB protector.
Here is my work, first I use the USB protector, then build the circuit, then connected wires with the H-bridge, and then connected them with the motor, however, the motor didn’t work well, so I asked the professor and figured it out– the reason is that I didn’t use the 12 VDC power supply and it results that the power was not enough.
Here is Joy’s work, we cut the board together and then she build the shell, finally we taped those paper on the shell to point out the different parts of the machanism’s shell, she also met a problem that when we finish our build, she found that the machine’s arm didn’t act correctly, professr told us that it’s because we put our top rail in wrong place.
After professor and teaching assisstant’s help and guide, we finally successfully complete the mechanism, I feel really proud about it because it’s the first mechanism built by me, by the way, my drawing is based on a character named Bronya in Honkai Impact 3rd, and when the mechanism working, it looked exactly like she is jumping, and I think that’s cute and also funny.
Answer to question 1:
I choose Danniel’s installation waves, it clearly use motor and elastic rope, although his work is much complicated and bigger then mine, but I think our basic are the same, we both decide to use a motor to act the mechanism, and I think the artist really did a nice job by using the motor, because motor can really made a mechanism powerful, and that’s exactly the artist want–to make his creation lively.
Answer to question 2:
Our project will be a simple tone player which can play seven scale, you can push one of the button, and the tone corresponding to it will ring, also lights the LED attached to it, in that way the operator can play some simple music and have fun with it. And here is basically what we gonna used in our project, also with the cardboard.
I think compared with animation, our project is more interactive because paople can play music they like, and by hand, rather than just listen to the program or touching the screens.
In all, this recitation meant speacial to me because it’s the first time that I complete a mechanism in group, which will obiviously impressed me for a long while.
