Westwell, a manufacturer of autonomous vehicles, has joined forces with Hesai, a leader in light detection and ranging (LiDAR) technology, to develop a fleet of electric vehicles tailored for port operations worldwide. This partnership aims to harness LiDAR technology to improve safety and efficiency in the movement of freight within busy shipping hubs.
The adoption of electric vehicle technology in larger freight and cargo vehicles, including semi-trucks and cargo ships, has faced significant challenges. While long-distance transportation of goods is essential, ports require a variety of support vehicles, such as trucks, tractors, and forklifts, to manage the complexities of freight movement. Unfortunately, these vehicles have not benefited from the same level of innovation in renewable energy as other sectors.
Challenges with Camera-Based Solutions
Ports demand a high level of precision for their operations, where heavy loads are transported in close quarters and various vehicles must operate efficiently in a fast-paced environment. While many autonomous driving systems have primarily relied on camera technology, using cameras alone in shipping yards poses several challenges.
Visibility issues in adverse conditions, such as rain, fog, and low light, can hinder a camera’s ability to detect obstacles accurately. In environments filled with heavy machinery and moving container stacks, cameras may struggle to provide reliable data, resulting in safety risks. Moreover, camera-based systems often require extensive calibration to navigate the unique complexities of shipping yards, and standard road algorithms may not apply effectively.
Cameras can also encounter difficulties with depth perception and 3D spatial mapping—critical elements in navigating the expansive, often unstructured environments found in ports.
The Promise of LiDAR Technology
LiDAR technology presents a potential solution by delivering precise distance measurements and 3D mapping capabilities. However, it is not without its challenges, including high costs and sensitivity to environmental factors like dust, salt, and inclement weather. The integration of LiDAR into autonomous systems is still evolving, and achieving seamless coordination with camera technology necessitates sophisticated algorithms and substantial computational power. These hurdles have slowed the widespread implementation of self-driving technologies in port settings.
Merging LiDAR with Advanced Algorithms
Despite these challenges, Hesai has made significant strides in long-term LiDAR development, amassing over 500 patents through its team of approximately 1,000 professionals. The company is now poised to adapt its innovations specifically for autonomous vehicles operating in ports.
Hesai’s LiDAR products feature laser lights capable of tracking distance and movement with an accuracy of within 5 millimeters, a critical level of precision in port operations where a single collision can result in significant freight loss. These autonomous trucks utilize LiDAR technology to gather vast amounts of data, which is uploaded to the cloud, allowing self-driving algorithms to analyze and optimize safety and performance.
The automotive-grade, ultra-high-resolution AT128 sensor, designed to integrate camera technology with LiDAR, enhances overall accuracy and functionality. With 128 channels, the sensor can detect over 1.53 million points per second, creating a detailed visualization of the surrounding environment.
This enhanced visualization will enable the deployment of multiple on-site electric vehicles with autonomous capabilities, allowing them to operate in harmony without risking damage to freight or other vehicles.
Addressing Broader Challenges
The collaboration between Westwell and Hesai aims not only to advance autonomous vehicle technology but also to tackle broader industry challenges, including reducing carbon emissions and addressing a significant labor shortage in the heavy equipment sector. Currently, the industry is facing a 9% shortfall in workers, a trend that is expected to continue as younger generations gravitate toward technology-focused careers rather than heavy machinery operation.
This partnership exemplifies the potential of collaborative efforts to adapt technology for innovative applications, particularly in the realm of autonomous driving within the complex environments of ports and shipping operations.
