Four Wheel Drive & Four Wheel Steering ROV Light
The main goal was to create a light surface robotic base without using tracks. Tracked vehicles are inherently heavy, hard to service and very inefficient at greater speeds. Also they have a fairly high COG, turn funny, scratch and mark all surfaces they touch. Our wheel based solution is easy to operate and maintain, light on its wheels on all types of off-road, paved and built-up terrain. It can crawl at a snail's pace, but it can still keep up with a running man on rugged terrain. It climbs stairs and can also negotiate 60°+ slopes on hard surfaces.
Features
Four wheel drive - Four wheel steering
Independent motor and steering control enables sideways crab motion, oversteered sharp turns, pinned down turns and even sideways shuffle with counter-rotating wheels
All metal construction, CNC billet aluminium frame
15km+ basic endurance, can be doubled without modifications
Basic real-time 4ch DVR/5 cam/video TX/telemetry camera payload on PTZ head with visible and infrared illumination
Optional high resolution thermal camera, gas sensors, etc.
Open telemetry system with high speed GPS and configurable OSD on the live video feed
Two complete sets of field replaceable wheels, a pendulum weight crawling wheel and soft rubber tyres for hard surfaces, built up areas and an all terrain mud wheel set for rugged off-road terrain
Technical specifications
Rigid axle coil spring suspension with articulating cantilever arms
Extreme structural flexibility, 85°+ frame articulation between the axles
Large caliber piggy-back shock absorbers with single/dual springs according to payload
Motor-on-axle (MOA) sensored brushless powertrain with active holding strength brakes
Dual redundant powertrain, steering and remote control options, the vehicle can lose all functions on one axle and it will still come home
