Indoor robotic platform

The Caster mobile robot is a versatile platform designed for both outdoor but primarily to the indoor environments. The robot overcomes door sills, raised covers or drainage channels and can move outdoors, especially on paved roads. Caster can safely carry loads of up to 75 kilograms.

The robot’s base is a differential wheel chassis with two powered wheels and two support casters. The larger wheel size and performance characteristics of the drives ensure a smooth transition through uneven terrain. The platform can be equipped with a robotic arm, RTV sensor Box for autonomous movement, or other equipment as required.



Thanks to the gearless drives, the Caster robot runs quietly and does not disturb its surroundings with excessive noise.

Powerful, maintenance-free

Maintenance-free drives give the robot high agility and the ability to move quickly and smoothly even on uneven surfaces.


Precise position control of the robot predestines it for operations that require high precision of the device movement in the environment.


The regenerative braking function also helps with a highly efficient drive, thus significantly increasing the operating time of the robot.


The load capacity of the chassis combined with a large loading area allows you to place a load of up to 75 kg or other necessary equipment.


The ability to use the robot in different environments and for different types of tasks makes it an adaptable robotic platform.


Caster as a disinfection platform

The interior robot can be used for delivering heavier objects, exploring the environment or disinfecting it. The platform can be equipped with a portable box, camera, robotic arm or germicidal lamp. The latter solution found its application especially during the pandemic. The action radius of the UVC lamp on the robotic chassis becomes movable, resulting in a significant reduction in disinfection time. The robot can be controlled with a joystick or use the autonomous mode with AI.


R&D platform

Basic platform suitable for universities and research institutions for algorithm development. It can be supplemented with sensor and software equipment as required, or outputs for other devices.


A platform suitable as a service robot controlled by a teleoperator using the application. It is possible to equip the robot with a sensor system, robotic arm or devices as required.


An autonomous platform designed for both outdoor and indoor environments. The robot is equipped with the RTV sensor Box and AON algorithm. The device is able to get autonomously to the specified position without collision and perform the task.
