Intel has asked the Federal Communications Commission (FCC) to make an exception for the automated guided vehicles (AGVs) that the company uses to transport the sensitive silicon wafers and other materials, containers, and supplies needed to make the most advanced chips in its fabs. According to Bloomberg, the American chipmaker fears that its AGVs would fall under the blanket prohibition against foreign-made robots after they were added to the FCC’s Covered List.

AGVs are niche machines that chip fabs use to transport materials and supplies between tools and sections of the fab, helping ensure that the cleanroom conditions required for each manufacturing process are maintained. This makes them critical equipment for U.S. semiconductor manufacturing, but, apparently, there are no suitable domestic alternatives for these devices at the moment. Intel’s current fleet of AGVs requires continuous maintenance, including software and firmware updates, and if it’s forced to find a local supplier for its AGVs, the company says that it would take years, crippling the United States’ chipmaking efforts.

The biggest AGV suppliers are Japanese companies like Murata Machinery and Daifuku Co., while a few smaller businesses from South Korea and Taiwan are also trying to break into the market. It’s unclear why these companies haven’t applied for a conditional approval yet, which would allow them to continue selling these products in the U.S. while also promising Washington that they’ll set up a manufacturing base in the country. This is something that Netgear has already done, allowing it to continue selling its foreign-made routers despite being an American company.

Intel says that it remains unclear if updates to its AGVs would break compliance with the FCC, and that it’s asking the agency to issue a conditional waiver “out of an abundance of caution to ensure the ongoing operation of these specific AGV units.” While Team Blue is the only company concerned about AGVs at the moment, other chip manufacturers would likely need a similar waiver in the near future, especially as they build more fabs in the U.S. This includes TSMC, which is planning to build 12 more fabs and four packaging facilities in Arizona, Samsung, with its new Taylor, Texas, fab, and even Elon Musk’s Terafab, which has already begun construction.

Washington has been using the FCC to force companies to invest in American manufacturing. Its blanket bans on foreign-made products like drones and routers have affected some of the biggest brands in the U.S., including DJI and TP-Link. While these bans do not outright ban the sale of all products made by these companies, especially those that have already been approved before, they make it impossible for them to introduce new products and even release software updates to their existing product line. The FCC eventually walked back on the software update ban, but they still would not be able to register new products unless they build them in the U.S.

A software engineer who’s also into drones and 3D printing has shared a single-motor drone that they built inside their home and tested on their bed. Joshua Bird shared a video of how they created it on YouTube, highlighting the unique technique they used to maintain controllability and stability. The design used a combination of a hinged propeller, rapid changes to the motor’s rotation speed, and a custom flight controller and motor controller firmware that allowed the motor to react to necessary changes in under 0.2 milliseconds.

Most rotary wing aircraft require a mechanism to counteract the torque generated by the motor or engine and to change its flight direction, typically with the use of a swash plate to change rotor disk attitude and a secondary propeller. While this method has been effective for decades, it has made rotary-wing aircraft heavier and more complex. This single-motor drone cut the need for a secondary mechanism by constantly adjusting the speed of the motor — speeding it up produces more reaction torque while slowing it down applies opposite reaction torque. This essentially turns into a balancing act between these two forces to reduce the torque on the drone body to a more manageable level.

The hinged rotor also relies on the same mechanism for directional control instead of relying on a swashplate. Each rotor blade sits on a 45-degree hinge that makes it pivot when the motor accelerates. As this happens, one blade pitches up to produce more lift, while the other blade pitches down, reducing lift. By accelerating and decelerating the motor as needed, Bird would be able to change the drone’s roll and pitch movement. It also combines this with the main rotor torque, motor adjustments, and the 3D-printed stabilizing fins to produce effective yaw control as well.

This was the theoretical part — the majority of the build video focused on fixing issues, including the part where Bird built a high-speed camera using a Sony camera and a flash unit controlled by a microcontroller that gets its signals from the prototype drone’s motor controller and camera shutter. This home-made high-speed camera revealed that the drone’s propellers were too soft and had to be replaced with a 3D-printed version that used sturdier filament.

The creator had to launch several test flights from their bed, many of which resulted in a crashed drone and some wall damage as they fine-tuned the drone’s programming. Bird was eventually able to make the 3D-printed drone fly, although it was limited to the bedroom because of its fixed-base IR beacon navigation method. They said that they eventually want to add a linear camera to the build so that it could take off in other environments in the future.

While other researchers and engineers have built smaller, quieter drones, with China even revealing a mosquito-sized unit, Joshua Bird’s single-motor project is still a unique take on drones. But what made the YouTube video much more interesting is the problem-solving process and the solutions that came afterward. You can check out the complete video below and even start your own similar project by looking at the Single Propeller Drone GitHub repository.

The U.S. Air Force has just successfully conducted an airborne test where an F-22 Raptor pilot directed an Anduril YFQ-44A Fury drone during simulated combat. According to The Defense Watch, the fighter pilot gave tactical commands to the autonomous wingman, which then interpreted them into a series of tasks and flight maneuvers to achieve the desired outcome.

The successful test is part of the USAF’s Collaborative Combat Aircraft (CCA), which seeks to integrate drones into fighter squadrons. These uncrewed aircraft must be able to respond to the fighter pilot’s tactical commands and then operate autonomously, though. That’s because fighter pilots already have a heavy workload — flying their own aircraft, managing sensor data, threat assessment, and weapons release decisions — so requiring them to manually fly a drone is next to impossible. Command integration means that the F-22 Raptor pilot could assign the Fury drone a specific tactical task, like monitoring for and engaging enemy air defenses, while they focus on the primary mission, such as taking out enemy fighters.

This does not mean that the USAF can start deploying drones alongside fighter jets in frontline squadrons, though. Successful command integration is just the first of several hurdles that the program must go through before it can achieve operational status. The program needs to determine the limits of the drone’s tactical autonomy, safe flight control, and weapons authorization, all of which are separate functions that must be tested accordingly. The Air Force also needs to see how the drone performs with electronic interference, and how it could continuously operate if it cannot receive instructions due to interrupted communications. Aside from figuring out the drone’s capabilities and incorporating it into fighter doctrine, it must also be integrated into the USAF’s logistics and supply chain. This includes drone maintenance and service, weapons handling, deployment procedures, and forward airbase operations with limited infrastructure.

Even though the latest test is seemingly successful, the CCA still needs to go a long way before it can start operational deployment. Nevertheless, the USAF is intent on pushing the project forward, as it sees autonomous drones as a force multiplier for crewed aircraft, allowing a single pilot to command multiple jets to achieve missions at a lower cost compared to using all-crewed aircraft. Other nations, like Sweden and China, are also experimenting with a similar concept of having a single operator take command of multiple drones, but the most significant difference of the CCA is that it focuses on air power instead of ground-based operations.
