In the field of high-altitude high-voltage power grid maintenance, manual live-line operations have always involved extremely high safety risks. In this video, we showcase a highly innovative industrial-grade specialized robot application: the Gorilla MK1 high-voltage transmission line inspection robot developed by Transgrid, Australia.
The robot innovatively adopts a rover-inspired bogie suspension system based on NASA’s Perseverance rover and is powered by CubeMars RI80 high-performance joint motors as the core drive units. It can autonomously travel along high-voltage lines, precisely climb, and easily overcome various cable fittings, ultimately freeing humans from dangerous high-altitude live-line maintenance operations.
High-voltage transmission lines are typically installed on towers in remote outdoor environments, where conditions are extremely harsh. For inspection robots, moving steadily on thin cables like “walking on flat ground” presents significant physical and engineering challenges:
Extreme Risks of High-Altitude Operations: Manual inspection requires workers to suspend themselves on high-voltage lines hundreds of meters above the ground, where the risks of electric shock and falling are extremely high. There is an urgent need to replace human workers with robotic systems.
Complex Cable Obstacles: High-voltage lines contain various obstacles such as vibration dampers, clamps, and suspension fittings. Robots cannot simply “go around” them; they must have the ability to overcome obstacles by climbing over or crossing the cable structures.
Harsh Outdoor and Electromagnetic Environments: The equipment must maintain absolute stability and reliability under strong electromagnetic fields, high winds, and extreme temperature variations. Any power failure could result in the robot falling.
To overcome these challenges, the Transgrid team introduced aerospace-level technology into power grid maintenance and developed an intelligent bogie-based chassis for the Gorilla MK1 using CubeMars RI80 motors. Its key advantages include:
Perfect Adaptation to NASA Rover Bogie Systems:The biggest highlight of the Gorilla MK1 is its inspiration from the rover rocker-bogie suspension system. This mechanical structure requires extremely high joint flexibility and strong load-bearing capability. With its compact design and high torque density, the CubeMars RI80 motor is perfectly integrated into each moving joint of the bogie system. It enables the robot’s wheel modules to automatically adjust their posture according to cable curves and obstacle shapes, allowing them to firmly “grip” or “cross over” the cable.
Industrial-Grade High Load Capacity and Extreme Reliability:When crossing heavy cable fittings such as vibration dampers, the robot needs to instantly generate significant pulling force and torque. The RI80 Series motors are designed for demanding industrial applications, featuring excellent overload capability and high mechanical strength. Even under extreme conditions such as suspended full-load operation or steep-angle climbing, RI80 can continuously deliver stable power output, ensuring the robot does not slip or lose speed.
Anti-Interference Capability and Precise Position Control:Strong alternating electromagnetic fields exist around high-voltage lines. CubeMars RI80 motors feature excellent electromagnetic shielding design and industrial-grade protection, enabling stable CAN bus communication even in high-interference environments. Combined with built-in high-resolution encoders and FOC algorithms, RI80 achieves millimeter-level position control accuracy, allowing the robot to perform complex obstacle-crossing movements in limited cable spaces.
Through this video, you can directly observe the outstanding performance of the CubeMars RI80-powered Gorilla MK1 in real high-voltage line environments:
Extreme Obstacle-Crossing Demonstration: Clearly showing how the robot uses its bogie system to smoothly overcome complex obstacles on high-voltage lines, including vibration dampers and cable clamps.
Autonomous Cruising and Climbing: Demonstrating the robot’s stable movement on steeply inclined cables, as well as its strong cable gripping and holding capability.
Reproduction of Rover Technology:Visually presenting how the chassis joints deform flexibly when encountering obstacles, similar to a rover navigating the Martian surface, while maintaining overall stability.
Q1: Why do high-voltage line inspection robots need to use a rover-like bogie system?
A: Traditional rigid chassis designs can easily become stuck or lose stability when crossing cable obstacles such as vibration dampers. Inspired by rover active bogie systems, the robot’s wheel modules and gripping mechanisms can move independently, allowing them to adapt to cable contours or overcome obstacles in real time. The CubeMars RI80 motor serves as the core component that provides the complex mechanical structure with the required flexibility and driving power.
Q2: Can CubeMars industrial-grade motors (such as the RI Series) operate in high-voltage electromagnetic fields and harsh outdoor environments?
A: Yes. CubeMars industrial-grade joint modules are designed with the requirements of specialized industries in mind. We provide solutions with high protection ratings (IP65/IP67 options), enhanced electromagnetic shielding, and wide operating temperature ranges, ensuring long-term reliable operation under extreme outdoor conditions such as strong electromagnetic interference, high humidity, and large temperature variations.
Whether it is high-voltage line inspection, pipeline inspection, or specialized robots operating in extreme environments such as high-altitude and underwater applications, CubeMars provides highly reliable, high-torque industrial-grade drive solutions.
