Soter Robotics :: Electric-Hybrid, Remotely Operated Robotic Platforms

Soter Robotics is a Serbian robotics company specializing in remote land management solutions. The company develops electric-hybrid, remotely operated robotic platforms designed for demanding landscaping, agriculture, and cargo transport tasks. Their core mission is to keep humans out of harm’s way by automating dangerous, dull, and dirty jobs on steep slopes, uneven terrain, and high-risk environments.

The flagship product is the SOTER robotic platform, a modular 333 kg rover available in three main configurations: SOTER Mower, SOTER Agri, and SOTER Cargo. All versions feature a fly-by-wire electric/hybrid powertrain with no hydraulics, offering quiet operation, lower maintenance, and reduced emissions. Key specifications include a 40° maximum slope capability, top speed of 14.1 km/h, hub motors delivering up to 800 Nm torque (modular 2WD/4WD), and an IP67-rated 10.4 kWh LFP battery pack (CATL cells, 5,000+ cycles).

The platform supports three control modes — ride-on, remote control (RC) with 2 km HD FPV video link, and full autonomy via ArduPilot with RTK precision. It uses a universal Category 1 three-point hitch compatible with standard tractor implements, plus an optional electric PTO (540–1000 RPM, bidirectional). Additional features include an electric winch, LED lighting, obstacle avoidance sensors, and a programmable 10 kW range extender with a 12 L fuel tank for hybrid operation.

The SOTER Mower includes a 120 cm electric mowing deck with three independent 1.2 kW brushless motors. The SOTER Agri and SOTER Cargo versions support cultivators, trailers, and material handling attachments. An Active Counterbalance system ensures stability with heavy tools. The company emphasizes measurable productivity (up to 5,000 m²/hour mowing), zero operator risk on dangerous terrain, and all-weather reliability.
