RPVD-3T - Getting Started
RPVD-3t is an Intelligence & flight controlling system in using PIC Base, Arduino & Java and SE & Web Base Controlling System.

RPVD-3T Stand for Remote Pilot Vehicle Drone 3 TravelingThis drone can controlling system in itself.

This drone has many fighting mode and specifications.

1. Attitude Mode

2. GPS Flight mode

3. Return to home

4. Intelligent Orientation Control

5. Lost control protection

6. Sports Mode

Flight mode

1. GPS Flight Mode

2. Headless mode/ Intelligent Direction mode

3. Lost Control Protection, hovering and auto pilot home

4. Low voltage protection

Drone specification

1. General Characteristic

2. Function Support PPM, PWM, S-BUS receiver

3. Superior Stable flight against strong wind

4. Gentle throttle setting

5. Precise spot hovering

6. Low voltage protection

7. Lost control protection

Maximum vertical speed: 6m/s

Maximum horizontal Speed: 118km/h

Attitude Mode

Switch the remote controller CH5 to Hovering mode, disarm the aircraft, and increase the throttle to 50% or the aircraft lift up the ground (depend on your throttle setting), the aircraft should be take off by now.

GPS Mode

Choose an area where do not have any high-rise building and no magnetic interference environment, connect with power, red LED light shall blink twice to entering in to satellite search mode, warm up around 1 minute, when the red LED light change from blink twice to slow blinking, the satellite searching is completed and the position locating is successful. Switch the remote control CH5 flight mode to GPS mode position (user can also switch to this mode during the flight), disarm your aircraft, increase the throttle to 50% and above level to make the aircraft lifting from the ground, aircraft shall be lifting vertically. After the aircraft reached the desired altitude, decrease the throttle to 50% level, the aircraft shall hovering at the height automatically, if the user adjust the aileron and elevation, the aircraft will keep flying at the height.

Return to home

This Drone will memorize the location where the user disarm the aircraft as home location, switch your remote controller to CH6 ( One button home mode), the aircraft shall automatically lifting to 20 meter height, keep the previous flying course, during the return flight, only the flying course can be control. Once the aircraft reach the home point, it will hover at the air for 2 seconds before descending slowly. During this time, user still can interfere with the remote control (but the throttle is being barred), this is to ease user to look for a suitable place for landing. After the aircraft landed, the motor shall spin slowly and stop. User shall put the throttle t minimum level, the flight controller will automatically arm after 3 seconds. Along the return flight, the remote control shall be restart and the flight mode switch shall be switching on-off from hovering mode and GPS mode, at the same time you should ensure the throttle lever is not at the lowest level in order to regain control over the aircraft again. If the remote control receiver encounter signal lost under the bad GPS signal, the aircraft shall landing at original ground.

Sports Mode

This Drone controller built in with two type of operation mode ?gentle mode and sport mode, the default mode is gentle mode. Only PPM and S-BUS receiver are able to switch between this two modes, CH7 will be used as the switch for gentle and sport mode. During the flight, you can switch between two modes in order to have different flying pleasure. Precaution: it is advisable that beginner user shall not change to the sport mode during the flight, shall only switch to this mode once the user flying skill become mature.

Intelligent Orientation Control

During the flight, switch the remote controller CH5 to Intelligent Orientation Control, and front direction is always the direction of nose when the aircraft take off. Detail as below: Red arrow represent the aircraft head direction, the green arrow represent the aircraft intelligence recorder direction.

Lost control protection

This Drone support lost control, first of all your receiver must support FS setting, after that you need to adjust the CH5 setting in the configuration software for the receiver lost control output value. Adjust the CH5 remote control transmitter green progress bar to ?lost control?, after that follow the Remote control instruction manual, do the proper setting on receiver lost control FS, then adjust the CH5 remote control back to the original range. After that switch off the remote control, the green progress bar shall be showing ?Lost Control?, with this, the FS setting is successfully configured. With the good GPS satellite signal, even if the receiver lost the signal, the drone Controller shall activate the auto pilot and return to home location (even in hovering mode or GPS mode). The auto pilot home will be same with the one button home mode.

This drone has a many sensors.

1. Accelerometer sensor

An accelerometer is an electromechanical device used to measure acceleration forces. Such

forces may be static, like the continuous force of gravity or, as is the case with many mobile

devices, dynamic to sense movement or vibrations. Acceleration is the measurement of the

change in velocity, or speed divided by time.

2. Gyro sensor

Gyro sensors, also known as angular rate sensors or angular velocity sensors, are devices that sense angular velocity. Angular velocity. In simple terms, angular velocity is the change in rotational angle per unit of time.

3. Ultrasonic sensor

Ultrasonic sensors use sound waves rather than light, making them ideal for stable detection of uneven surfaces, liquids, clear objects, and objects in dirty environments. These sensors work well for applications that require precise measurements between stationary and moving objects.

4. Motion sensor

A motion detector is a device that detects moving objects, particularly people. A motion detector is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area. Motion detectors form a vital component of security, automated lighting control, home control, energy efficiency, and other useful systems.
