The new tracked robot—available in several variants—is increasingly chosen over wheeled versions. While crawlers offer superior off-road capability, production can be slightly more costly. The planned design uses a welded frame of light alloys (angles, flats and plates) to maintain strength with the lowest possible mass.
The structure and dimensions ensure adequate stiffness and strength while keeping total mass low. The frame is divided into mounting zones for drive units, power-transmission mechanisms, electronics and power systems, plus auxiliary drives to raise/lower the auxiliary tracks.
Analyses and tests confirmed the case for crawler drive. The system comprises two pairs of tracks: main (direct-drive) and auxiliary (indirect-drive). Each track has its own independent drive unit—motor, planetary gearbox and a drive sprocket mounted on the output shafts. Shaft design allows wheels to mount directly on the gearboxes. The front-mounted auxiliary tracks have additional drives for raising/lowering.
Given the need for high torque in limited space, the drive combines a motor with integrated brake and encoder, working with two harmonic drives linked by a belt transmission.
Between the main tracks in the centre frame section there are two battery enclosures housing eight cells—designed to provide at least one hour of operation per charge.
A top-mounted deck plate enables fast, universal mounting of different modules—sensors, a transport basket, a manipulator or sampling systems.
Overall, the tracked robot is a modern, innovative design that provides real support for work in difficult terrain and specialist applications.
