📱Common Applications

RoboDot offers a range of applications, prominently featuring its integration with drones as a local RTK base station, eliminating the need for an internet connection while providing very short baselines. Additionally, RoboDot supports long-range operations through its repeater mode. It facilitates the collection of ground control points in three different methods, allowing for versatile and adaptive workflows that can be combined based on specific application requirements.

RTK Drone Integration

Flying drones with RTK GPS has benefits in surveying and navigation. When surveying, images will be geotagged with accurate images relative to the base position.

First connect the controller to the RoboDot wifi, then connect or configure the Custom RTK network in the controller. Use the following credentials:

• Host: The IP on your RoboDot screen, typically 192.168.4.2

• Port:10,000

• Mount Point: X

• User: X

• Password: X

Reference this YouTube for an example with the DJI M3E.

Drone controllers with web browsers can be used to access the Web UI.

Benefits

• Accurate image geotagging

• Enhanced navigation

• Local base advantages over online VRS

Setup Options

1. Relative Positioning:

   • Place RoboDot

   • Connect drone controller to RoboDot Wi-Fi

   • Use Auto Survey or Average from GPS

2. Absolute Positioning:

   • Follow relative steps

   • Add base position coordinates

   • Option: Connect via shared access point

3. Shifting:

   • Operate under Relative Positioning steps

   • Post flight shift images using RoboDot Utility

Long Range Operations

When a project's scope is too vast to be managed from a single point, mobility around the site becomes beneficial. However, relocating a local base station and re-establishing it at a new site can be cumbersome. Moreover, moving the base station may introduce errors into the project. Therefore, it is often better for all rover and drone data to refer back to a single base point. In such instances, RoboDot can be utilized in Repeater mode to increase the operational range to up to 1km.

Reference this Youtube on how Repeater mode works.

Ground Control Points

Ground control points are commonly used in photogrammetry for map correction and referencing. GCP coordinates can be obtained in many ways including:

Static Observations

RTK Rover Mode

RTK Drone and GCP Collection Combined

Example: RTK Flight with GCP Collection post flight

1. Follow the RTK drone integration steps

2. Complete drone flight

3. Select the appropriate Base Reference:

   1. Single RoboDot options:

      1. Switch to Rover Mode with VRS

      2. Record the Rover observations for PPK processing

   2. Dual RoboDot option:

      1. Use a second RoboDot as Rover with Lora Radio to reference the base

4. Collect GCPs with the Rover
