Overview
PALLAS.75 is the compact UGV platform from ALPS.Robotics — a series product built on years of advanced development. Tracked drive, a robust CNC-machined aluminium housing and a modular payload interface make it a versatile carrier for civil applications indoors and outdoors.
The platform is based on the already productive ZELOS series, from which the current PALLAS product family has evolved. Proven mechanics, series-production maturity and documented spare-parts availability are therefore in place from day one.
Chassis & running gear
- Drive concept: tracked drive — 2× drive sprocket (spoked wheel in aluminium casting), 2× road wheels per side
- Drive sprocket diameter: approx. 269.55 mm
- Track width: 60 mm
- Overall dimensions: 720.59 × 382.73 × 269.55 mm (L × W × H)
- Track gauge (centre–centre): 262.67 mm
- Ground clearance: 62.29 mm
- Housing: CNC-machined aluminium parts, black anodised or powder-coated
- Payload plate: supports mounting of up to 2 payload modules
- Ergonomics: central carrying handle on the underside plus side handles left and right
2026 control architecture — three-layer model
The control electronics were redesigned in 2026 — modular, future-oriented and with a fully China-free supply chain right down to chip level:
- Mission computer (Linux + ROS 2) — mission logic, navigation and operation. Based on TQ-Systems TQMa8x or Kontron congatec i.MX8 SoM (Germany/Austria, NXP silicon). Documented supply chain and 10+ years of long-term availability.
- Real-time controller (STM32 or Infineon AURIX) — safety-critical I/O, emergency stop, sensor fusion and odometry. STM32 from France/Italy; for higher safety requirements, Infineon AURIX TC3xx (Germany/Austria) is available as an alternative.
- Servo drive layer: Maxon EPOS4 — CANopen CiA 402, up to 750 W continuous / 1500 W peak. Directly paired with the existing Maxon motors. Made in Switzerland (Sachseln).
This approach saves considerable development time: the CAN bus topology is retained, EPOS4 removes the need for in-house motor-controller development, and there are large open-source communities at every layer (ROS 2, STM32Cube/Zephyr, CANopenNode).
Modular payload
A wide range of superstructures can be mounted quickly via the payload interface:
- LiDAR and camera systems for autonomous navigation
- Manipulator superstructures (e.g. NEXOS.Nova as a cobot payload)
- Sensor transport (environmental monitoring, gas detection, thermography)
- Customer-specific tool carriers and mission modules
Typical applications
- Plant inspection — substations, wind farms, industrial sites, critical infrastructure
- Civil security — fire brigades, police, civil protection and rescue services (see the Civil Security industry page)
- Research and teaching — open firmware on GitHub, ROS 2 native, an ideal starting platform for academic UGV projects
- Surveying and mapping — indoor and outdoor with a LiDAR payload
- Autonomous logistics in industrial environments
Software & ecosystem
The firmware is being rebuilt from scratch on the new 2026 control architecture. The firmware source code is publicly available at github.com/andix76/pallas75-firmware. Together with the KyROS software (Python, CANopen/EPOS4), PALLAS.75 provides an open, well-documented entry point into mobile robotics.
PALLAS product family
PALLAS.75 is the entry model in a growing series. Larger variants such as PALLAS.150 and above are in development — for higher payloads, longer mission times and more demanding operational profiles. For military use there is the parallel ODIN series from NEXOS.Defence.
Product allocation: PALLAS.75 is a product of
ALPS.Robotics — the civil robotics brand of the NEXOS.Group. For defence applications, see the parallel series
ODIN.75 to ODIN.2400 from
NEXOS.Defence.
