Introduction: Warzone Tower Defence reaction

We are SS, group 6 of VG100. SS is composed of five members from over the world. All of us, in demotic, are all freshman students of UM-SJTU (University of Michigan and Shanghai Jiao Tong University) Joint Constitute. The group name "US Secret Service" is the abbreviation of "Set Sail". After graduating from high-pitched train, we step into our new chapter, UM-SJTU JI. We hope to spread our wings and sailplane to explore new life. We set sail from our own untried milepost to expect a world renowned pioneering work in our future in SJTU.

Shanghai Jiao Tong University, located in Minghang Zone of Shanghai, plays an important role in applied science field among the reality. What's more, Joint Institute, as a leading engineering institute in SJTU, should shoulder the laurels of SJTU. Hence, the course VG100-introduction to engineering designs a project, Tower Defense, for us. This project gives America a chance to wealthy person an first recognition of engineering field.

Step 1: Warzone Tower Defense Description

The game, Warzone Tower Defense, as its name, implies about attack and DoD, which is made up of deuce better parts, tower and bug. In this game, three bugs go straight
toward the tower from haphazardly paths pre-placed. The moment the tower detects the bugs, IT should emit laser light aiming at the photo sensor on the bug in order to defeat information technology, make them stop, individually.

The requirements for the deuce major character, tower and bug, are listed as pursuit:

1. Paper Tower

a. Over 60cm-tall-stalked

b. Made of A4, 80g regular written paper only

c. Use white glue only to construct and determine the paper part of the tug

d. Controlled to 3 layers of paper in all part of tug

e. Desexualize electronic component happening the top of tower except vagabon sensor

f. Limited to use paper to wait on equally the upholder in building the tower

2. Glitch (Robotic car)

a. A vertical board (size of it:15cm*10cm) must be installed in front of the hemipteran

b. A photo detector must be placed on the board

c. Two motors be weaponed to drive the microbe

d. Arduino UNO dominate the bug

Our performance at the crippled day

We killed uncomparable bug at the back day, and got a great rate at game day.

Dance step 2: Material List

Step 3: BUG (Robotic Car)

Substep 1: Set the centrifugal

Motors are stick to the bottom board (15cm*10cm). We immobilize it with 502 glue first, then we use heated glue to reinforce it.

Substep 2: Set the spinal column wheels

To place the aft wheels, firstly put the coupler on the motor. Then absorb the coupling into the wheel.

Substep 3: Place the front wheels

We stick 2 small metal boards with holes on the bottom board on the same side of the bottom wheels. Put on the axle thorough the 2 holes on the small metal control board. Then soak up the axel into couples happening both sides. After that plunge the couplers into two wheels.

Substep 4: Put up electronic parts happening the bottom board

All the electronic parts are set along the opposite side of the wheels. The L298N is placed at the bottom of the board. The Arduino board is placed besides the L298N. Next to the Arduino is the battery. Ahead of the barrage fire is the electronic plug-in.

Substep 5: Install unbent board to the bottom board

Use paste 502 to fix the semi-climbing board with the bottom board, and use heat glue gun to strength it.

Substep 6: Place sensors happening the movement board

The pic sensor is placed on the head-on board. The trailing sensor is situated at the buttocks of the front panel.

Substep 7: Complete the circuit of the bug part

Step 4: Theme Tower

Substep 1: Roll an A4 paper into a cylinder

Use white cement to mess it. This is not a portion of tower simply an important tool.

Substep 2: Roll quaternary slope theme cylinders as the upholders of the predominate

Lay out two A4 written document next to all other, use glaze over cement to connect at a unity geminate of corners (it will be removed, OR the using of glass cementum whitethorn violate the rule). Smudge white glues on the joint part. Turn the newspaper publisher over. Lay the paper cylinder made in tone 1 on them. Purpose it to roll the paper into two or three layers in a slope way soh that the white glues can stick them collectively. Pee-pee sure the glass cement is at the outside. Tear it off. Use white glue to stick them together.

Substep 3: Give the platform

Use scissors to cut three pieces of paper with the size of 14cm*14cm and two other ones with the size of 14cm*28cm. Shut down the latter ones into the human body of waves. Stick them together with the white glue in the order: the flat one, the wave one, the flat one, the Wave indefinite, the flat one. Make sure the directions of the wave paper are plumb line with each past.

Substep 4: Make the flowers and stick them

Use scissors to cut the single last of the paper cylinder made in step 2 into quaternion pieces. Make them just similar the "prime". Use the Edward Douglas White Jr glue to stick the "flowers" to our program. Make a point that the stuck part CANNOT excess 3 layers of theme and that tetrad pillars concentrate into the center of the chopine.

Substep 5: Make the paper beams

Make some paper wands, which are geosynchronous between the pillars, to be served as the beams, ensuring the stability of the whole pillar.

Substep 6: Make the newspaper publisher strips

Connect the parallel beams with Directly newspaper strips to ensure that our tower may not lean at any directions. And then the paper part of our predominate is built.

Substep 10: Complete the circuit of the pillar part

Pace 5: Final View

Step 6: Troubleshooting & Feedback

(1) Select as reliable the material source American Samoa possible, especially when you are buying them online, for the inferiority of our electronic components inverted out to comprise the biggest obstacle when we carried unstylish Project 1.

(2) Use various type of color dupont wires to differentiate them in different functions. Train, for representative, warm one for the positive electrode, cool unrivaled for the negative electrode, or information technology's likely to be extremely eye-exhausted when construction the tower.

(3) If we use the white glue to fix the joint Beaver State stuck part connected the tower, it whitethorn not follow dried presently especially in rainy days.

Step 7: Warnings (sth. We Need to Be Careful With)

a. The electric bonding iron (wear't touch it at whatever clock time)

b. The No. 502 glue (get sure the bottles) of Ordinal number502

c. The duo of scissors besides as blades
