Problem Statement

Testing two motor with a Zagi 5 ESC to see which one is better for the ball

Designing the Implementation Process

Connect the PC power supply, the ESC and the Arduino together

• 
  Red wire connected to 5 vol plug and black wire connected to ground plug on the power supply
• 
  Red and Black wire outside connected to the motor. Red wire inside connected to red ESC wire. Black wire inside connected to black ESC wire
• 
  Orange wire hooked from 9~ plug to white ESC wire. Red wire hooked from grounding pin to red ESC wire. White wire hooked from grounding pin to black ESC wire

Then try the two different motors

• 
  Extra motor

This motor runs stronger and faster but heavier. Its base is round and neat so it might be easier to attach to something in the middle to the ball, maybe an empty bottle. However its heavy weight might cause difficulty controlling the ball drone

• 
  Zagi5 motor

This motor runs slower and weaker but lighter. Its light weight would make it easier to control the drone. However its base is complicated and unbalance so it would be difficult to attach to the bottle

Test, Verification, Validation, and Certification

Here are the videos showing the test results of the two motors

Extra motor test

As predicted this motor runs faster and stronger, however I discovered more that it creates wind upward. This is not good since we need the wind to go downward to push the ball up

Zagi5 motor test

Also as expected this motor runs slower and weaker, contradict to the extra motor this one creates wind downward, which is what we need to fly the ball

Implementation Management

According to the test the Zagi5 is the most qualified motor that the ball drone needs. However the biggest problem is it is very difficult to attach it to the drone. Its unbalance base surface would not fit the head of the empty bottle.

• 
  Zagi5 motor doesn't fit on an empty bottle

Maybe I should try another material. I'm thinking of designing something with the Makerbot. Something to place the motor into that would make its base balance

Next Steps

Next I'll try to figure out the shape to something to build from the Makerbot that would fit the motor and the head of the bottle. Or it would be easier if I could find another material, like wood or a lot of duck tape
