Robotic Combat Lewiatan ZS Polish Unmanned Assault-Reconnaissance Vehicle

Lewiatan ZS

Cooperation between WB Electronics, Hydromega and Military Technical University has led to creation
of remotely controlled vehicle - Lewiatan ZS in reconnaissance (ZS-R) and armed (ZS-U) version. Lewiatan ZS has big ability for moving in different terrain type and its big loading allow for installing necessary components and modules. This vehicle is able to drive on asphalt roads as well as off-road. Driving
platform has 2200 kg weight, max speed of 55 kph, 1500 kg payload and is able to tow up to 2200 kg trailer.

This small vehicle (length 3500 mm, width 2000 mm, height 1950 mm) has 4 cylinder, 2800 ccm petrol
engine with 92kW at 3600 tpm. Lewiatan base version is a 6 wheel platform, which construction allows for overcoming trunks, trenches and swamps. Wide, low pressure tires allows for low pressure on the ground (approx 20 kPa). Thanks to it, the vehicle is able to drive in boggy or muddy terrain. Driving platform of Lewiatan has many advanced systems.


Steering, control and data transmission concept of Lewiatan ZS system was split into two systems:
placed on a vehicle and on the base station. Information transmitted between vehicle and base station are using Harris military data link. This radioline secures range up to 50km in open terrain and up to 1 km in urban terrain (depending on building density). For observation and for steering Lewiatan is equipped with several CCD cameras, thermal cameras, GPS receiver and sensors such as e.g. laser scanners. For combat purposes, as a specialist device, 12,7mm machine gun and smoke grenade launcher were installed. Due to the fact that driving platform has 1500 kg payload it is possible to adapt other sensors or devices (it is also facilitated by the module communication system of the vehicle).

Robotic Tank
Up till now Lewiatan ZS is adapted to being remotely controlled by operator (or operators) from the base
station basing on information coming from vehicle sensors. It is planned that further work will go into direction
of creating vehicle being able to conduct mission fully autonomous.
