Hesai Technology looks to make next-gen vehicles safer and more reliable using its advanced LiDAR
As passenger mobility becomes electric and more technologically advanced, engineers have developed several components to make car travel easier, more efficient, and, most importantly, safer. One of those emerging technologies is LiDAR, which has several benefits for OEMs who integrate it. Hesai Technologies is one of the leading companies helping make that LiDAR-centric transition possible.

Hesai Technology is a global leader in LiDAR solutions
Hesai Technology ($HSAI) is three-dimensional light detection and ranging (LiDAR) specialist with offices all over the globe, including Shanghai, Palo Alto, and Stuttgart.
It currently employs over 1,000 personnel who help research, develop, and manufacture advanced LiDAR technologies for a number of applications, including Advanced Driver Assistance Systems (ADAS) in passenger and commercial vehicles, autonomous driving vehicles, as well as last-mile delivery robots and Automated Guided Vehicles (AGVs).
With over 500 granted patents and another 1000+ pending, Hesai puts a lot of time and effort into its LiDAR research and development, and the result is a growing portfolio of advanced safety sensors that can help pave the way for next-generation vehicles coming to market.
LiDAR remains a viable option for next-gen road safety
As advanced driver assistance systems (ADAS) and autonomous driving applications become more prevalent, the question of whether to use LiDAR sensors, vision cameras, or both is becoming hot topic of debate and an increasingly important one.
Many OEMs have shifted from LiDAR ADAS and self-driving applications to a camera-based vision approach, but environmental factors like lighting and weather conditions can cause confusion.
The automotive and robotics industries are racing against one another to advance from Level 2 autonomous driving (where the driver must keep their eyes on the road and hands on the wheel), to Level 3 and L4 autonomy, where the driver is no longer responsible for driving the vehicle. In these applications, Hesai Technology argues that LiDAR, like its ultra-thin long-range ET25 sensor, can make an effective difference while enhancing safety both on and off the road.
The camera conundrum
Cameras have been integral to the development of autonomous vehicles and ADAS vehicles, providing visual inputs like human eyes, and still exist as a viable option to an extent. They can provide valuable color information and visual cues such as traffic light status and road sign recognition.
Furthermore, opting to integrate only one kind of sensor, i.e., cameras, saves on production costs which can be passed along to consumers.
However, cameras can struggle in challenging conditions. They rely heavily on lighting in a vehicle’s given environment, and their performance can be significantly affected in low light or direct sunlight scenarios, presenting potential safety hazards.
Furthermore, cameras capture two-dimensional images, making depth perception and accurate distance measurement more challenging. These potential limitations underscore the need for more robust perception technology that can provide more information about what’s truly happening in the surrounding environment.
Hesai LiDAR can help enhance safety
LiDAR, such as the AT512 from Hesai, uses laser pulses to scan the environment in three dimensions in real-time. This enables a vehicle’s onboard computer to understand its surroundings, offering a reliable and effective solution to the limitations presented when using camera technology alone.
Hesai Technology’s LiDAR is unaffected by lighting conditions, ensuring consistent performance day and night, and in various weather conditions, including fog and heavy rain, where cameras can sometimes struggle. This independence from external light sources makes LiDAR an effective tool for self-driving vehicles, ADAS, and robots that require reliable and constant navigation capabilities.
Another advantage of LiDAR is its ability to detect objects with high precision and measure their distances accurately. This capability is crucial for vehicles operating on public roads at high speeds, which need to identify hazards, such as pedestrians, other vehicles, and obstacles, from a distance and react accordingly to avoid accidents.
Companies like Hesai have also made significant advances in how LiDAR can be integrated into vehicles, cost, and data security. For example, Hesai’s new ATX LiDAR can be integrated into headlights for a sleeker, subtle design. Moreover, significant advances in LiDAR technology and how it’s manufactured have made it much more affordable, allowing automotive and robotics manufacturers to incorporate the technology without major cost increases for consumers.
Many people don’t know that as hardware, LiDAR is quite secure as it provides data to the vehicle or robot’s central computer for processing without any ability to store or transmit any data wirelessly because it lacks memory, Wi-Fi, Bluetooth, or cellular transmitters.
It also cannot collect biometric data, such as facial scans, because it’s a sensor, not a camera. Furthermore, the 3D maps LiDAR creates of the world around it are not detailed enough for said images.
Tech stacks that maximize safety
Although as a LiDAR technology developer, Hesai would argue it offers superior capabilities in object detection and environmental mapping, the company admits its sensors are most effective when used in conjunction with camera systems.
Camera technology has laid the groundwork for the development of autonomous systems, but LiDAR can help overcome the inherent limitations of cameras and ensure the unparalleled safety that consumers and regulators demand. Combined with vision cameras, Hesai’s LiDAR sensors, like the automotive-grade ultra-high resolution AT128 for instance, can offer vehicles a one-two punch in failsafe ADAS technology.
Hesai explains that the integration of LiDAR technology has already shown promising results in enhancing safety across various applications. In the automotive industry, LiDAR-equipped vehicles have demonstrated improved obstacle detection and collision avoidance capabilities, significantly reducing the risk of accidents. With LiDAR technology rapidly evolving, its integration into new applications is quickly becoming more widespread.
The future of autonomous driving is not just about leading the charge but doing so with the assurance that every possible measure for safety has been employed. As the industry moves forward, Hesai Technology strongly believes the combined use of LiDAR and camera systems will be pivotal in achieving the highest safety standards.

The latest hybrid telehandler from New Holland packs a range-extending combustion engine to boost its battery power during longer shifts – but it doesn’t run on gas or diesel. Instead, this farm-friendly machine is built to run on METHANE.
By collecting pig, cow, or poultry waste (poop), silage waste (corn husks and grass clippings), and food waste from composting and putting into a manure digester, farmers can generate valuable biogas – a renewable, low-carbon fuel that can be burned for heat, electricity, or used as fuel. And because large farming operations can produce huge amounts of biogas at an incredibly low cost compared to conventional grid and fuel costs, any machine that can run on biogas is going to have a real total cost of ownership (TCO) advantage.
Biogas generator
CASE and New Holland (collectively, CNH) understands its customers’ desire to put that biogas to good use. They also understand that nothing is quite as efficient as battery-electric power, though; but big farms have weird duty cycles: 4-6 hour shifts most of the year, then critical, un-skippable, non-negotiable round-the-clock running during harvest.
That need to run 24 hour shifts limits the appeal of pure electric machines, and has led to companies like ZQUIP developing power-agnostic modules that swap-out, power tool-style, to keep the machines going. With its new methane hybrid, New Holland is going a more recognizable EREV and hybrid route.
“With this prototype, New Holland shows its continuous commitment to the ‘Clean Energy Leader‘ strategy, building on our leadership in alternative fuel machines,” says Marco Gerbi, New Holland T4 and T5 tractor, loader and telehandler product management. “Our aim is to help our customers boost farm productivity and profitability by broadening our range of alternative fuel machines that do not compromise efficiency or productivity yet help to minimize agriculture’s carbon footprint.”
Primarily driven by a 70 kWh lithium-ion battery, the telehandler uses a methane-fueled version of Fiat Powertrain’s four-cylinder F28 engine as a range-extending backup whenever jobs demand more uptime. On the energy stored in the battery alone, New Holland says the machine can handle a full day’s worth of typical farm work — roughly a “350-day duty cycle,” and it can recharge from the grid, a biogas generator, or even rooftop (barntop?) solar.
It’s still just a prototype, but New Holland claims the hybrid setup cuts fuel use by up to 70% compared to a conventional diesel telehandler while delivering 30% better performance and uptime for its operators.

Elon Musk’s Boring Company has work crew in Nashville walk off job over unpaid bills and safety
The Boring Company, Elon Musk’s tunneling startup, is reportedly facing significant issues with its new project in Nashville, Tennessee. A key subcontractor has walked off the job, alleging that the company has failed to pay for work completed on the “Music City Loop,” claiming they have received only 5% of what they are owed.
We have been following The Boring Company’s expansion efforts closely.
After the relative success of the Las Vegas Loop and several projects that failed to materialize, it looked like the company was winding down until a new proposal in Nashville gained some momentum.
However, a new report from the Nashville Banner indicates that the project is hitting a major wall.
Shane Trucking and Excavating, a local contractor hired to handle preliminary work for the tunnel project, pulled its workers off the site this Monday. William Shane, the owner of the company, told the Banner that The Boring Company has “ghosted” them and failed to pay invoices totaling in the six figures.
According to Shane, the payment terms were initially set for every 15 days, then unilaterally switched to 60 days. Now, he claims it has been over 120 days since they broke ground, and his company has received only a fraction of the payment due.
“We were really skeptical from the beginning, and then since then, things pretty much just went downhill,” Shane said.
The contractor was reportedly responsible for preparing the launch pad for “Prufrock,” The Boring Company’s proprietary tunnel boring machine (TBM). We previously reported on Prufrock’s capabilities, with the company claiming it can dig tunnels significantly faster than conventional machines, supposedly porpoising directly from the surface to avoid digging expensive launch pits.
If the launch pad isn’t finished because the excavator wasn’t paid, Prufrock isn’t digging anywhere.
This isn’t the first time we’ve heard of payment issues involving Musk-led companies. Tesla has been known to not pay its bills, leading to small companies going bankrupt.
As The Boring Company was stiffing Shane on the bills, the company tried to poach workers from its own contractor and lied about it:
“One of their head guys texts two of my welders, offering them a job for $45 an hour from his work phone,” Shane described, noting that the same TBC employee denied sending the texts when confronted with screenshots. “That’s actually a breach of contract.”
On top of the missed payments, Shane alleges serious safety concerns. They made several official complaints to OSHA:
“Where we’re digging, we’re so far down, there should be concrete and different structures like that to hold the slope back from falling on you while you’re working. Where most people use concrete, they currently have — I’m not even kidding — they currently have wood. They had us install wood 2x12s.”
The Boring Company Vice President David Buss blamed missed payments on “invoicing errors” in a statement to the Banner:
“It does look like we had some invoicing errors on that. It was, you know, unfortunately, too common of a thing, but I assured them that we are going to make sure that invoices are wired tomorrow.”
He also said that he would look into the poaching allegations, but added that he is not aware of any OSHA complaints.
The “Music City Loop” was pitched as a solution to connect downtown Nashville to the airport, a route that is notoriously congested.
The Boring Company claims it can complete the project without public money, but there are some obvious issues with its financing.
Electrek’s Take
I’ve been willing to give them the benefit of the doubt on the “Loop” concept. While it falls short of the original “autonomous pods” vision or the “Hyperloop” speed dreams, the system in Las Vegas does work to move people, even if it is just Teslas in tunnels driven by humans.
There’s just no evidence that it would be more efficient than any other public transit system.
When Musk launched The Boring Company’s first test tunnel in LA, I asked him if he had any simulations showing his “loop” system to be more efficient. He said that they were working on that. That was 7 years ago.
Therefore, while The Boring Company appears to have achieved marginal improvements in tunnel boring, mainly when it comes to smaller tunnels; it has yet to show clear evidence that its Loop system is a better solution than any other public transit system.
