Veronte Gimbal is a high quality device designed to be used in unmanned aerial vehicles.
While using a visible and thermal (optional) cameras, this two axis gimbal provides to any aerial platform high quality sensors essential for any professional task that could require the use of drones.
The gimbal has been designed to be effectively used either in big or small platforms, keeping a light weight and compact size without leaving the enclosure which protects the cameras it embeds.
We have developed four differents variants of Gimbal:
|Camera||Zoom||HQ Thermal Camera|
|Veronte Gimbal:||HD||x10||Yes, 320x256 resolution|
|Veronte Gimbal SC:||HD||x10|
|Veronte Gimbal Pro:||Full HD (1080p/60)||x30||Yes, 640x512 resolution|
|Veronte Gimbal Pro SC:||Full HD (1080p/60)||x30|
Veronte Gimbal takes into account airspeed for refrigeration. When used for indoor operation, it will eventually get warm. Consider using an external source of refrigeration for indoor operations longer than 1h.
|Veronte Gimbal SC:||136mm||112mm||730g|
|Veronte Gimbal Pro:||209mm||149mm||1575g|
|Veronte Gimbal Pro SC:||194mm||149mm||1485g|
Veronte Gimbalshould be attached to the platform using 4x M3 screws, using the threads located on the upper surface.

System connections will be established through a connector LEMO FGG.2B.310.CLAD72Z with 10 pins.
LEMO FGG.2B.310.CLAD72Z connector
Outputs received from the system connector are:
- Power 24VDC: Used for video system powering and gimbal electronic controllers. Nominal values are 24V and 0.416 A (10 W).
- CAN Bus: It is used to command gimbal’s position, stabilization of the system and for changing different parameters from Veronte Gimbal.
- Ethernet: Its utility is based on allowing the user to receive video streaming in real time from both cameras.
- Analogic Video: A composite video output which carries camera(s) available signal to the system.
Besides connector Lemo, it will be provided the same connector version but with its panel model connector, with which the different platforms integration may be ease.
The pin-out for the connector is as follows:

Pinout setup example
When supplied voltage, Veronte Gimbal will perform an initial check. Please make sure that Gimbal movemente path is clear before powering it up.
Veronte Gimbal is controlled by commanding an angular position by means of a set of CAN messages. Veronte Gimbal also continuously broadcasts information about its state that can be read by any device connected to the CAN bus. The format of the CAN Data messages to communicate with Veronte Gimbal is the following:
- CAN Baudrate: 1000000 Bd
- Extended ID: No
- Endiannes: Little Endian
Messages sent by the controlling device in order to send commands to Veronte Gimbal.
Angle command messages
Format for the messages that the controlling device must send in order to control the position of the Veronte Gimbal:
- ID: 1 (Pitch) and 2 (Yaw).
- Period: 0.05 s (recommended)
Nº of Bits Value Info 1 0-1 Motor off (0) or Motor on (1) 1 1 Matcher with value 1 32 0-360 Angular position between 0º and 360º
Veronte Gimbal has a physical limit when moving upwards, which corresponds to 0º Pitch. Correct neutral position for Veronte Gimbal is 0º Yaw - 90º Pitch.
Messages sent by Veronte Gimbal through the CAN bus. These messages can be read by Veronte AP and stored into variables:
Messages containing the position of the servos read by the encoders.
- ID: 34 (Pitch) and 35 (Yaw)
Nº of Bits Value Info 32 0-360 Current encoder position between 0º and 360º 32 0-360 Current commanded position between 0º and 360º

Below is a step-by-step process on how to configure Veronte Gimbal using Veronte PIPE. This configuration is designed to control Veronte Gimbal using a Virtual Stick on the Veronte Pipe Workspace.
We will first rename a set of user variables to use them for storing control values. For information about how to configure user variables visit: User Variables Configuration
|Gimbal Yaw Output||0||Stores the desired position for the Veronte Gimbal Yaw|
|Gimbal Pitch Output||0||Stores the desired position for the Veronte Gimbal Pitch|
We will be using a Virtual Stick located on the Veronte PIPE Workspace to control the position of Veronte Gimbal. First we will need to check that control through Virtual Sticks is enabled for our configuration. Go to Setup/Devices/Stick/Virtual Stick and check the following values are correct:
Virtual Stick configuration
Then we will create a Virtual Stick Widget on the Workspace and assign the channels we want to control. In this case we will use stick channels 9 and 10:
Virtual Stick channel selection
Finally we need to check that our Virtual Stick is on. In order to do that click on the antenna icon on the top left of the Virtual Stick widget. When the stick is correctly recognized, the Mode indicator on the Veronte pannel will turn green. Value of stick channels can be monitored displaying variables ‘Stick Input’ r9 and r10. Remember to save the Workspace for the new variables to be loaded correctly:
Virtual Stick connection checking
Now we will create a set of operations that will use the chosen user variables to control the position of Veronte Gimbal. The following operations have to be located on the ‘Continuous execution’ list (Right side). Operations are executed in order from first to last so maintaining the order established below may be important:
First operation will be the one controlling the commanded position for the yaw angle. This will be simply a value provided by the stick. Since the stick range goes from 0 to 1, this value will be multiplied by 360 to get a full 0º-360º range. We will also add a Yaw correction, using the attitude of the platform, to keep the current gimbal yaw even if the aircraft changes its yaw angle. We will use a Linear Expression type operation:
The operation for controlling Pitch will be similar, but this time range will be from 70 º (slightly tilted up) to 180º (looking down):
Pitch operation configuration
Last step is configuration of CAN messages according to 4.1. Below you can find a set of screenshots showing how build the correct messages in Veronte PIPE:
