Version: 3.5.0

Release Notes 3.5.x

info

As Ubuntu 20.04 is reachng End of Support, Seoul Robotics is sunning down its support for that operating system and invites users to migrate to Ubuntu 22.04 or 24.04 at their earliest convenience.

Version 3.5.8​

Dec 22nd, 2025

LiDAR Connection​

  • CHANGED | Updated ROS2 driver for Quanergy LiDARs

Version 3.5.7​

Dec 16th, 2025

Platform​

  • NEW | LiDAR coverage viewer (Occupancy Grid) Analized and visualized spatial LiDAR coverage using ground level profile and ray-casting to identify blind spots.
  • CHANGED | Optimized behavior for 3D maps
  • CHANGED | Optimized ground profiling
  • CHANGED | Improvements around NaN points and removal of noisy log folders.

LiDAR Connection​

  • CHANGED | Experimental support for Quanergy LiDARs with ROS2
  • CHANGED | Reduced CPU resource usage of Robosense Airy driver by 20-50% (dependent on computer hardware used)
  • CHANGED | LiDARs can be sorted using drag and drop within a given algo node

Version 3.5.5​

Nov 9th, 2025

Platform​

  • CHANGED | Algo node no longer increases the algo node count if it only contains mirrored LiDARs

LiDAR Connection​

  • CHANGED | Updated Opsys driver following firmware update.
  • CHANGED | Updates for Robosense Airy setting a hardcoded maximum range of 50m due to distorted lidar packets emitted by the sensor, added option to configure stacking capability to prevent blindspots due to distorted backets.
  • CHANGED | Updated JT128 to add fallback option to use saved calibration file if it cannot be retrivec. CPU consumption optimization.

Version 3.5.4​

Oct 2nd, 2025

Platform​

  • NEW | Option to use 3D point cloud map as reference for Auto Ground Profiling
  • CHANGED | Allow 3 decimal precision for scaling background map
  • CHANGED | Throttled noisy logs from Ouster and Hesai driver

LiDAR Connection​

  • CHANGED | Improved Hesai driver to handle the case where we cannot communicate on the PTC port with the sensor
  • CHANGED | Reduced CPU resource usage of Robosense Airy driver by 20-50% (dependent on computer hardware used)

Version 3.5.3​

Sept 24th, 2025

LiDAR Connection​

  • CHANGED | Allow the user to change Ouster FOV settings to reduce volume of data sent by sensors.

Version 3.5.2​

Aug 27th, 2025

Platform​

  • CHANGED | Optimized the merger algorithm to improve performance, previously some significant delay could be experienced in setups with multiple algo nodes larger than 500m x 500m.

Version 3.5.1​

August 12th, 2025

Platform​

  • CHANGED | Added environment variable `SENSR_ALGO_NODE_COUNT` into single machine installer to select the maximum number of algo nodes that will be created by the instance (Default: 3)

Algorithm​

  • CHANGED | Minimum cell size for ground profiling reduced to 0.05 meters

LiDAR Connection​

  • CHANGED | Updated Ouster driver that led LiDARs to appear with a 180 degrees-shifted yaw compared to 3.4.x

Version 3.5.0​

July 21st, 2025

Platform​

  • NEW | Base operating system upgraded to Ubuntu 22, with SR Launcher support extended to Ubuntu 24.
  • NEW | Full migration to ROS 2, replacing the previous ROS 1 integration.
  • NEW | Added support for NVIDIA Jetpack 6.
  • CHANGED | Docker image sizes significantly reduced and loading parallelized for faster startup times
  • CHANGED | The single-machine installer now supports up to 3 algo nodes to allow zone-based parameters.
  • FIXED | The ROS Subscriber Interface now automatically restarts if it stops receiving data.
  • FIXED | Corrected a bug related to the recovery of an algo node after an update.
  • CHANGED | The system now automatically selects a default preset based on hardware: 'Outdoor GPU' if a GPU is available, and 'Indoor' otherwise.

Algorithm​

  • CHANGED | The Clusterer and Event Zone logic has been optimized for performance.
  • NEW | Added an option to refine deep learning bounding boxes for improved accuracy.
  • FIXED | Fixed a crash caused by a missing zone name in background removal configurations.

LiDAR Connection​

  • NEW | Added support for the Hesai JT128 LiDAR.
  • NEW | Added support for the Hesai Aeva Atlas LiDAR.
  • CHANGED | Updated drivers for Hesai, Ouster, Seyond (formerly Innovusion), Livox, and Luminar for operating on ROS2 (previously ROS1). Added automatic parameter conversion for updated LiDAR drivers to ensure seamless transitions.
  • REMOVED | Removed LiDAR drivers for Aeye, Baraja, Blickfeld, Cepton, Leishen, Livox (Mid-40, Mid-70, Tele-15, Horizon, Avia), and Luminar (Hydra).

Visualization​

  • NEW | Each object's point cloud can now be visualized in a distinct color for easier identification.
  • CHANGED | The native GUI now displays object trails by default to better track movement.

Web-Frontend​

  • FIXED | Resolved an issue that prevented adding or editing LiDARs.
  • FIXED | Corrected a bug where configuration changes were not applied due to a type mismatch.
