Introduction: Germ Tower Defence

We are Team HUAJI, from the UM-SJTU Joint Establish (JI) and this was a plan made for our VG100 course of study. The JI was recognised between Shanghai Jiao Tong University and the University of Michigan in 2006. The university is located in the Minhang district of Shanghai, China, with one of the best engineer professors and instructors in the cosmos. The tap tower defense was the first project of VG100 and information technology aimed to develop our group operative skills and served as an introduction to engineering.

The Bug Tug Defense is a competition composed of two primary sections- the loom and the pester (robotic elevator car). The target of the game is to putting to death the bugs in the shortest period of time with a optical maser that is placed connected the tipto of the pillar. The laser is programmed with an arduino to scan the light sensors on the bugs in order to kill them. The bugs are also intentional and tested aside every group.

Below are the challenger regulations:

Track:

- 2.5m abundant

- Shelter area to prevent the bugs from getting killed in the 2-2.5m surgical incision inaccurate from the tower

- Colourless line midmost of the track paralleled to both sides of the path

- White line in front the predominate vertical to the sides of the path

Bug:

- Mustiness include a vertical board (15cm*10cm) in the front of the bug

- Light sensing element mustiness be placed in the center of the vertical board 5 cm above the soil

- Must stop when killed (scanned by laser)

- Mustiness go around in a straight line

- Must end for 2-4s happening the white line of reasoning settled before the pillar and can not be killed when stopped up for this duration

- Fastness in range of 0.2-0.3m/s

Tower:

- Made of lax A4 ninepenny newspaper publisher (80g) and hot wood glue

- Maximum 3 sheets of paper stacked allowed anywhere on the tug

- Electric components mustiness be placed on top of the inning the loom except for sensors (allowed at the bottom if required)

- No other materials are allowed to support the tower other than paper

- Must be leastwise 60cm grandiloquent

- Needs to be able to kill the bugs by turning the optical maser to whatever angle

Step 1: Groom Materials

Step 3: Circuit Diagram for Bug

Figure 2.1 shows the lap diagram for the bug.

Step 4: Component Fabrication for Bug

  1. Cut the acrylic board into a 15cm*20cm rectangle as the basis (Board A)
  2. Cut another acrylic board into a 10cm*15cm rectangle atomic number 3 the front (Board B)
  3. Recitation holes with 3mm diameter 1.5cm separated from for each one other straight along the sides of instrument panel A 5mm away the 20cm edge and 1cm absent the 15cm edge (figure 3.1) (for easy adjustment in the ulterior)

Step 5: Assembly for Bug

  1. Solder a wire on some the positive and the negative end of the motor for both motors (figure 4.1)
  2. Connect both wheels with the motors and fix with screws (figure 4.2)
  3. Chute the motors into the efferent holders and screw them into two of the holes at the end of circuit card A with screws and drive in caps (figure 4.3) (make a point the two wheels are parallel)
  4. For the following steps stick the components with double-sided tape
  5. Stick the arduino UNO on top of Board A 9cm from the front of the germ and 2.5cm from the remaining side of the bug (work out 4.4) (the side with the wheels is the cover of the bug)
  6. Joint the bread board happening top of Board A 9cm from the front of the bug and 3cm from the right side of the bug (see 4.5)
  7. Stick the driver board happening upper of Circuit card A 3cm from the back of the wiretap and 5cm from the right English of the bug (figure 4.6)
  8. Stick the battery on transcend of Board A 3cm from the front of the tap and 5cm from the right side of the bug (public figure 4.7)
  9. Stick the two turn wheels on the bottom of board A face-to-face the motor-wheels 3cm from the front of the germ and some 5cm from the sides of the bug (figure 4.8) (pretend sure the wheels are parallel)
  10. Stick the board B vertically against board A with double-sided tape (15cm go with against 15cm face)
  11. Stick the tracing sensors on the bottom of board A two at the center 2cm apart and one at the very socialistic end (at the ending with the hierarchic circuit board and with the sensors sticking outwards)
  12. Stick the light sensor at the centre of board B pointing in front of the hemipteron (digit 4.9)
  13. Connect all components to the arduino UNO with wires (hold up wires in lieu with sticky tape)

Step 6: Circle Diagram for Tower

Figure 5.1 shows the circuit diagram for the tugboat.

Step 7: Paper Collapsable for Hul

  1. Draw three vertical lines 6.8cm apart from each other and the long edge of the paper (figure 6.1) (should end up having three even rectangles and some other selfsame thin rectangle with 7mm breadth)
  2. Fold the paper from step 1 on for each one credit line in the synoptical direcion
  3. Brush the smallest rectangle with mucilage and puzzle out it tight to the edge of the furthest rectangle (figure 6.2) (should finish with an equilateral triangle prism and make sure the side with gum is on the inside layer)
  4. Ingeminate steps 1 to 3 eleven more multiplication (end up with 12 trilateral prisms)
  5. Fold a paper from the shorter edge in a zig-zag all 1cm (figure 6.3)
  6. Glue a piece of paper on some sides of the undulation-wish newspaper publisher from step 5 (figure 6.4) (don't use too overmuch glue, only skirmish some against the pointy ends of the brandish-like theme)
  7. Repetition steps 5 to 6 twice Thomas More
  8. Cut a paper into a strip with 10.5cm breadth (figure 6.5)
  9. Fold the wallpaper into a polygonal shape optical prism with 6.8cm sides and glue into form (calculate 6.6, 6.7) (use up the unexpended percentage for gluing)
  10. Repeat step 9 iii more times
  11. Roll a newspaper publisher vertically into a cylinder with 6cm diameter and glue into shape
  12. Repeat step 11 three more times
  13. Glue the short sides of deuce pieces of paper together by 5mm (figure 6.8) (should close upwards with a report with length around 70cm)
  14. Track the newspaper from ill-use 13 into a strip with width 10.5cm (figure 6.8)
  15. Glue the strip from step 14 into a cylinder (visualize 6.9)
  16. Cut composition into hexagon with 7.3cm sides and cut out small triangles 5mm bass at every edge (figure 6.10)

Step out 8: Forum for Tugboat

  1. Place 6 of the triangle prisms put together into a hexagonal prism (figure 7.1)
  2. Halt the triangle prisms in put down with the hexagon strip (cypher 7.2) (make secure the hexagonal prism is tight away adjusting the size of the striptease)
  3. Stick the hexagon paper connected both ends of the hexangular prism (figure 7.3)
  4. Repeat steps 1 to 3
  5. Stick the cardinal hexagonal prisms in concert end to end (figure 7.4)
  6. Stick two of the wave paper onto the bottom of the tower from step 5 Eastern Samoa the base and one wave paper on the lead of the tower as the stand (figure 7.5) (make sure the tug is at the midpoint of the A4 paper)
  7. Stick the 4 paper cylinders around the bottom of the tower on the base from step 6 and make sure the cylinders are fashioning liaison with the tower (figure 7.6) (the cylinders take to be even spread into the 4 corners of the tower)
  8. Wrap the tetrad cylinders put together with the report discase (make believe for certain they are skin-tight jointly by adjusting the size of the strip)
  9. Connect arduino UNO with the extension board (compute 7.7)
  10. Bind the optical maser Spanish pointer on top of the step motor with sticky tape (make sure the laser is straight and in the center of the step motor)
  11. Stick the step motor along summit of the extension board from step 10 with double sided tape
  12. Stick the arduino UNO from step 11 to top of the tower with sticky tape
  13. Connect wires to the 4 motion sensors (make a point the wires are long enough to elongate from the extension board to the bottom of the tower)
  14. Stick the 4 motion sensors onto the paper strip on the bottom of the tower between the cylinders on all 4 directions with sticky tape (make a point the motion sensors are all at the center between the cylinders and at the same height with each opposite)
  15. Join wires from all components to the extension circuit card Stick the stamp battery on the top of the tower closely next to the arduino UNO with sticky tape
  16. Stick the battery on the top of the tower closely next to the arduino UNO with mucilaginous magnetic tape

  17. Trim the roll paper on the top of the hul to the shape of the column (figure 7.8) (make doomed totally components are non hanging out of the paper)
