When you are a child, do remote control cars in the shop attract you? Do you feel sad when you can’t own a car and play with it? If the answer is “yes”, why not build your own remote control vehicle—a hovercraft now? You can make a hovercraft as long as you follow our manual. This task was initiated from course Vg101: introduction of Engineering at UM-SJTU Joint Institute. 5 freshmen students formed a team called "Angelnearing" to build a wireless control hovercraft. It will take two people 4 hours to finish the hovercraft.

Step 1: Preparing materials
· Blower Knife
· Ducted fan Scotch tape
· Servo Pencil
· Electronic speed controller Compass
· Conversion interface Double-sided foam tape
· Arduino and breadboard shield Screwdriver
· Dupont Line
· Plastic bag
· Insulation foam
· Rigid foam
· Cellphone with Bluetooth
· M3 screws and nuts
Step 2: Programming
Download the controlling program to your Arduino
- Download Arduino software into your PC; the website address is http://arduino.cc/en/Main/Software#toc1
- Connect your Arduino Uno singlechip with your computer. If the LED light on the singlechip isn’t lit, reconnect the singlechip.
- Warning：If your PC has never connected with a Aruduino before, install a plug-in.
- Paste the code into your arduino software. Click upload bottom on the interface. The code is in the appendix.
Step 3: Cutting boards to build main structure
Cut two 25cm*30cm baseboards.
- Draw a 5.8cm*3.3cm rectangle 3cm away from one of the shorter sides of the baseboard.
- Draw another 4.3cm*2.0cm rectangle 2.5cm away from the other shorter side of the same baseboard.
- Cut along the edge of these two rectangles by a knife and remove them.
- Dig four holes around the 4.3cm*2.0cm rectangle (two holes on each side).
- Waring: The size of the holes should be smaller than the size of the nuts.
The figure 2 is the size of each part on Baseboard 1.
- Cut two 18cm*3cm bars from the other baseboard. Cut the corners of the board as 4 4cm*4cm triangles
The figure 4 is the size of each part on Baseboard 2.
