Maintenance

Proper maintenance is vital for keeping your CoDrone happy and healthy.  Here are some tips to help you maximize your CoDrone’s life:

Battery

The CoDrone uses a 3.7V, 300mAH, 15c Lithium-Ion Polymer battery.

Functionality:

To charge your CoDrone battery, slide it in to the BYROBOT charger and connect the charger to a USB port.

If the battery is charging or idle, the BYROBOT charger will show two red LED’s.  If the battery is fully charged the LED’s will turn off.

Maintenance:

LiPo batteries are very picky when it comes to maintenance.  Follow these rules to maximize your battery life:

  1. Don’t leave the battery in the charger if you don’t plan to use it.
    • LiPo batteries are not meant to be fully charged for too long.  They will overheat and are unsafe when charged for extended periods.
  2. Don’t store your batteries fully charged
    • LiPo batteries that are fully charged will deteriorate more quickly.  It is best to store LiPo batteries with about half charge.
  3. Keep your batteries in a temperature controlled environment
    • Like most batteries, LiPo batteries will prone to heat and moisture damage.  Keep your LiPo in a safe, room temperature environment.

Propellers

The CoDrone uses two UNIQUE propeller designs.  One spins clockwise, and the other spins counter-clockwise.

Functionality:

The CoDrone’s propellers are oriented in a very specific format.  Two of the four propellers spin clockwise, and the other two spin counter clockwise:

The reason for this goes into some complicated physics.  The main thing is that the opposing motors cancel out each other’s net torque.  This prevents the drone from constantly yawing (rotating sideways).  Failing to follow this setup will result in your drone not flying properly, and likely not flying at all.

Maintenance:

Propellers are the most vulnerable component on the CoDrone because of their high relative velocities to anything they might crash into.  Keep yours in top condition to avoid any problems:

  1. Propellers are extremely aerodynamically sensitive.  If your propeller has a crack or chip in it, it may cause your CoDrone to lean to one side or become unbalanced.  Make sure to inspect and replace your propellers as often as possible.
  2. Make sure your propellers are clean.  Avoid hair and fibers.
  3. Try not to fly into stationary objects…

Replacing your Propellers:

The CoDrone propellers are designed to be easily pulled off:

  1.  To remove your propellers, just pinch the motor with one hand and pull the propeller off with the other.
  2. To replace a propeller, just align the through hole with the shaft and squeeze the propeller back on.
  3. Remember that propellers are DIRECTIONAL, and must be placed in the format shown above.

Motors

CoDrone motors are two-way DC motors.

Functionality:

DC Motors are controlled entirely by voltage.  A DC motor will run faster with a large voltage, slower with a small voltage, and reversed with a negative voltage.

Maintenance:

CoDrone motors are easily detachable from the main body.  Just pull it off to detach.  Inspect your motors often to clear away any obstructions or buildup:

  1. Hair can easily get caught in the shaft and wound tightly.  Be sure to pull of your motors and inspect the shafts carefully.
  2. A bent shaft can cause a lot of problems.  When adding and removing propellers, be careful not to push too hard.

Base

The CoDrone controller has an array of sensors and circuits.  Take good care of it to not damage any of the on-board components.

Maintenance:

  1. The base contains the majority of your CoDrone’s vital hardware.  Keep it in a safe, dry place at all times.  Don’t fly outdoors or over wet ground.
  2. The base also contains multiple IR sensors and an low resolution distance camera.  Keep these surfaces clean to ensure proper operation.
  3. Keep the base away from any magnetic objects.
  4. The top and bottom of the base separate easily when pulled apart.  Use this to remove any debris that might be stuck inside the body.
