Mining technology integration company Dwyka Mining Services has launched US-based robotics developer Boston Dynamics’ quadruped robot, known as Spot, in South Africa, targeting a variety of mining applications.

Dwyka MD Jamie van Schoor says Spot can be used in the mining industry for seismic surveys, gas detection, laser scanning, conveyor belt line and tunnel inspections and search-and-rescue operations.

He adds that the robot also has a particular application in no-go or low-manoeuvre areas, as it is able to traverse difficult terrain at both its normal height and in a crouching mode. Spot is also able to easily recover from falling over, in addition to constantly maintain good balance following knocks.

The robot has been designed to conduct autonomous operations, such as routine “autowalks” in aboveground plants and operations, as well as underground.

It can also be controlled remotely by an operator, who has 360º visibility as a result of forward-facing, side and rear cameras, enhanced in low-light environments by infrared capability off the shelf.

Dwyka demonstrated two versions of Spot to South African mining companies, namely Spot Explorer and Spot Enterprise, the latter being more adaptable to autonomous operation, as it can dock itself to a charging and data-offloading station that also offers a quick charge function.

Wheeled and tracked robots are limited by stairs, gaps and ground-level obstructions such as cabling and staged materials and minor height differences in flooring.

While aerial drones work well for exterior site and facade monitoring, they struggle when it comes to constrained environments, battery life, payload and path repeatability, according to Boston Dynamics.

Spot’s animal-like mobility enables it to navigate these environments easily without the same constraints faced by drones and wheeled/tracked robots. Spot can also easily traverse stairs.

It can carry various payloads of up to 14 kg, including a high-resolution and zoomable camera; light detection and ranging sensors; thermal imaging; auditory sensors to identify audible leaks such as compressed-air leaks; and food, water and medical supplies for search-and-rescue operations.

In search-and-rescue operations, Spot can also be configured to carry lights, a microphone and a speaker to facilitate two-way communications with trapped persons.

A dedicated Spot Arm version is also available. It comes fitted with a manoeuvrable arm, which cannot be removed and can interact and collect items, and open doors.

Spot can be controlled using a remote controller linked to Xbox gaming consoles, thereby enabling anyone who has used an Xbox to more easily adapt to using Spot robots.

Early adopters of Spot used the robot to document construction progress, monitor remote or hazardous environments and provide situational awareness.

Spot robots have been used in a variety of environments, including power generation facilities, decommissioned nuclear sites, factory floors, construction sites and research laboratories.

The robots have also been used to explore projects for creative industries, such as dancing on stage and performing in theme parks.
