HELIX AR2 – Amphibious Robot


​​HELIX AR2 is an 800 kg amphibious robot with a central payload deployment tower consisting of a rack and pinion mechanism used to deploy instruments and samplers into the tailings or soil up to 4 m deep. A sample magazine is used to store several samples per trip. Copperstone has developed HELIX, a family of autonomous field robots to collect mission-critical data in hazardous environments. Copperstone has modernized the screw-drive vehicle and adapted it to work as a robotic platform specifically for environmental monitoring and tailings investigations. The patented screw drives are pontoons that enable flotation, with a helical grouser acting as a propeller when spun at high speed in the water. At low speeds, the vehicle can crawl through soft mud deposits or act as a wheel on hard ground. HELIX has many advantages over other modes of propulsion and is perfectly suited to the variety of terrain and seasonal conditions encountered on tailings.


Goes anywhere

HELIX amphibious robots can successfully traverse hard ground, mud, tailings, snow, ice, and water. With 4-screw, skid-steer capabilities, HELIX can manoeuver specialized payloads into the most inaccessible of terrains.

Ability for heavy payloads

HELIX is designed to float on water or saturated soils and muds. Its large deck platform and high buoyancy allow heavy work such as water and mud sampling or geotechnical measurements, and add-on tanks allow for high push and pull forces.

Health and safety

Workers remain in safe environments while robots do the dangerous work. This is not only good practice, but a significant cost savings as well. HELIX can even be used to tow a stranded boat and/or be modified to act as a rescue vehicle.

Cost savings

Robots require fewer labour and equipment hours and are less expensive than conventional equipment, allowing more timely information to be gathered at lower cost. Robots can be used with fewer safety planning hours and be operational more quickly.

Green solution

Our electrically-operated cleantech robots have no emissions and can be made intrinsically safe to help industrial operations become more sustainable.

Remote Operations

HELIX Dash software enables the coordination of both autonomous and remote operational capabilities without placing humans at risk. Giving the user ultimate control over the rover.


HELIX Dash is a modular application comprised of various plugins used to monitor, control, and visualize various aspects of the rover and its payloads.
