Opening our doors

You can start looking at our product , but we shall be opening our doors on March 2019.

What we do.

We design and build drones for amateurs and professionals alike, who wants to use drones in their private capacity.

Trinity-MK-II

This is a quad-copter using the 450 frame-size. It is fully programmable with many manual and automated flight modes. Also included, are all the safety features as mentioned in the safety section.

Trinity-MK-III

This is as hexa-copter using the 550 frame-size. It is fully programmable with many manual and automated flight modes. Also included, are all the safety features as mentioned in the safety section.

Our drones has the following features (model dependant )

  • Manual and fully automated flight modes
  • Automated flight modes include GPS based waypoint flights ( GEO , UTM , MGRS )
  • Automated flight modes include “Return to home” , Position-hold , Auto-landing
  • Dual radio ( short range & long range )
  • Dual GPS
  • Fully automated failsafes ( Battery , Radio , GCS , EKF , Geo-fence )
  • GPS is based on M8N chip ( GNSS GPS , GLONASS , Galileo , Beidou , QZSS and SBAS )
  • Flight controller is an industrial controller with triple redundant sensors ( accelerometers , gyroscopes , barometers ) which are vibration damped
  • Dual compasses ( one internal, one external )
  • Camera option 1 : 1200 TVL daylight
  • Camera option 2 : 800 TVL , 0.00001 lux Infra-red assisted night
  • Camera option 3 : TBA

Safety

Safety features on our drones

Every drone has a flight controller that is advanced in many ways. Amongst these features , are a comprehensive set of safety features. These features are configured in such a way that the chance of a lost or fly-away drone is minimal. The safety-features are however not a replacement for a well informed and trained user. We therefor recommend a training-cycle for any user wanting to fly a drone.

Before releasing a drone from the factory, every drone is also tested on the testing field to check , not only its safety features, but also its flight modes.

Rules for flying drones in South Africa

To use a drone in a private capacity, there are some rules that are important to take not of. On the right hand side , are two links that will list these rules.

The rules can be found HERE and HERE.

 

Where can I fly my drone

 

Based on the rules of flying , a map was created to assist in guiding people to safe places where they can fly their drones. This is only a guide and users are urged to do their own research based on their own situation.

The map can be found HERE .

Battery safety

  • Pick up a LiPo battery by its body, not the leads – the wires could be pulled off from the fragile solder joints.
  • Charge at safe places – It’s very important to find a fire-proof location to charge your batteries. Using a Lipo-safe bag is a good option, some even build a bunker for it. An ammo box is a cheap yet effective solution.
  • Don’t charge your battery immediately after using it, wait until it has completely cooled down.

The points on the left are only a few taken from the link HERE .

On the link above there is a comprehensive list together with an explanation of some of the terms used when dealing with batteries.

Technical information about drones

Many people tend to stay away from drones because they are not sure about how-and-why.  In an attempt to shed some light on this, we have provided some information about how drones fly.

Very basically a drone consists of a frame , a controller and a propulsion system. ( We will leave out the receiver , GPS , telemetry system and camera system for now ).  In the controller is a gyroscope and accelerometers which detects the attitude and movement of the drone. This tells the controller what the drone is doing. This information is then combined with the instruction from the pilot ( via the radio ) so that the controller can determine what signals to send to the motors. During this process there is also a controller called a PID-controller involved, to “smooth-out” this action.

The basics of motor-control to achieve flight in certain directions , is explained HERE .

The PID-controller is there to smooth-out the control of the motors to ensure that the drone flies smoothly. The theory behind the PID-controller and its design is rather complex and it includes complex maths. But the link HERE should give someone an idea of its actions. 

In the link above it also explains how these parameters are tuned.  We use the automated tuning process where the drone actually adjusts these parameters automatically based on the actual response of the drone.
