Relu Robotics has deployed its Bison Series photovoltaic installation robot in Algeria, bringing AI-powered robotic technology to international solar construction projects. The deployment represents an important milestone in the commercialization of intelligent robotics for renewable energy infrastructure and demonstrates how embodied intelligence can transform traditional solar construction workflows.

As renewable energy construction faces labor shortages, rising operational costs and increasingly complex working conditions, Relu Robotics is developing embodied-intelligence solutions that bring AI into physical industrial operations. Beginning with solar construction, the company’s robotic systems are designed to augment human capabilities and enable more efficient, precise and reliable operations in demanding outdoor environments.

From Photovoltaic Infrastructure to Outdoor Embodied Intelligence

Relu Robotics team has developed a full-stack technology platform covering high-precision outdoor 3D perception, intelligent decision-making, and flexible robotic control.

Built on this foundation, the company has created the Bison Series photovoltaic installation robot, a pioneering commercial application of “outdoor precision-operation embodied intelligence.”

The technological path pursued by Relu Robotics differs fundamentally from the traditional evolution of automation toward intelligence in highly structured environments, such as manufacturing production lines. Instead, Relu Robotics directly addresses the far more challenging and impactful problem of applying embodied intelligence in complex, unstructured outdoor environments.

In demanding outdoor operating conditions, robots must cope with a wide range of uncertainties, including intense sunlight, wind and sand, rain and snow, uneven terrain, high-altitude environments, and other unpredictable factors. Maintaining stable, efficient and precise operation under these conditions presents a significant engineering challenge. Relu Robotics addresses this challenge through a combination of high-precision 3D perception, intelligent decision-making and adaptive motion control.

Engineered for Utility-Scale Solar Construction

The Bison Series robot is purpose-built for ground-mounted photovoltaic power plants. With an overall weight of approximately 9 tons, the platform provides the stability required for demanding outdoor operations. Its robotic arm supports a payload of up to 50 kg and features an effective working range exceeding 5 meters, allowing it to handle mainstream large-format, high-power PV modules used in today’s solar industry.

Powered by Relu Robotics’ proprietary high-precision 3D perception technology and adaptive motion-control algorithms, the system achieves:

1. Less than 3 mm perception accuracy

2. Less than 0.5° bracket-angle recognition error

3. Installation accuracy within 5 mm

4. Sub-millimeter repetitive positioning accuracy of the robotic arm

These capabilities enable the robot to deliver laboratory-level installation precision while operating in harsh outdoor conditions, including sandstorms, intense sunlight, and extreme temperature fluctuations.

Built for Extreme Environments

Solar farms are often constructed in remote areas where traditional labor faces significant operational challenges. The Bison Series was engineered specifically for these conditions.

The robot features:

1. Maximum climbing capability of 20 degrees

2. Travel speed of up to 4 km/h

3. Operation at elevations up to 5,000 meters

4. Working temperature range from -20°C to 60°C

5. Vehicle protection rating of IP54, with core components rated IP65

Combined with a high-performance 3D vision system designed to withstand strong light interference, the platform has completed extensive field validation in regions including Inner Mongolia and Xinjiang, where sandstorms, high temperatures, and significant temperature variations are common.

Long-Range Operation for Remote Solar Sites

To support continuous operation in remote locations, the Bison Series adopts an extended-range power system equipped with a 200-liter fuel tank.

Based on a typical 10-hour working day, daily fuel consumption remains below 20 liters, enabling up to 10 days of continuous operation on a full tank.

For remote solar construction sites, operational endurance is a critical factor — reducing downtime and improving overall project efficiency.

Improving Efficiency, Safety, and Reliability in Solar Construction

Solar developers and EPC contractors worldwide are facing common challenges:

1. Extreme heat and prolonged outdoor working hours

2. Dust and sand affecting equipment reliability

3. Uneven terrain requiring flexible mobility solutions

4. Increasing difficulty in recruiting and managing large construction workforces

Relu Robotics’ photovoltaic installation robots are designed to help overcome these challenges by automating repetitive and physically demanding installation tasks.

Compared with traditional manual installation, robotic automation can significantly improve consistency and reduce component damage. While manual PV module installation typically results in damage rates of approximately 0.3%–0.5%, Relu Robotics’ automated paving process reduces this figure to below 0.01%, improving both construction quality and project economics.

How AI-Powered Solar Installation Robots Work

The Bison Series integrates three core capabilities: perception, intelligent decision-making, and robotic execution.

First, the robot uses advanced vision systems to identify PV modules, mounting structures, and surrounding environmental conditions.

Next, its AI control system analyzes the environment, plans movement paths, and calculates precise positioning requirements.

Finally, the robotic arm performs the installation process by picking up photovoltaic modules, transporting them to the designated location, aligning them with mounting structures, and completing accurate placement.

By automating these repetitive operations, solar developers can accelerate construction schedules, reduce labor dependency, and improve worker safety.

For Relu Robotics, photovoltaic installation represents the starting point for a broader embodied-intelligence platform focused on precision outdoor operations. The platform is designed to enable robotic systems to perceive their surroundings, make task-specific decisions and execute physical operations in complex, unstructured environments.

From solar construction to agriculture, forestry, specialized industrial operations, and other outdoor applications, Relu Robotics aims to develop adaptable robotic systems powered by a common perception–decision–control architecture.

Rather than pursuing general-purpose humanoid robots, Relu Robotics takes a vertical-industry approach, beginning with clearly defined operational challenges where task-specific intelligent machines can deliver practical value. The company believes the next stage of AI development will be defined not only by how machines reason and learn, but also by how effectively they perform useful work in the physical world.
