Around 300 ALHs { Advanced Light Helicopter } of various varieties, including the Mk1, Mk2, Mk3, and Mk4, also known as the Rudra Weapon System Integrated, are flying with the three forces and the Coast Guard. The Army operates around 145 indigenous ALH, 75 of which are Rudra, with another 25 ALH Mk-III on order and due to be inducted over the next two years. The Air Force has around 70 ALH in service, the Navy has 18, and the Coast Guard has 20 ALH.

The ALH is a critical fulcrum for the services, including the Army, Navy, and Air Force. It is a utility helicopter that was designed in 1983 and is utilised across the services for a variety of duties, including personnel and material transport. 

Following three separate accidents of ALH Dhruv in quick succession , Bengaluru-based Hindustan Aeronautics Limited has decided to replace a key component of the Dhruv Advanced Lightweight Helicopter in order to improve the fatigue tolerance of the made-in-India chopper, which serves as the rotary-wing mainstay for the Indian armed forces.

According to sources, the state-owned aviation will replace an aluminum-made control rod in the gearbox with a much tougher and corrosion-resistant material. This improves both the copter's fatigue tolerance and the pilots' control of the aircraft.  

Insiders said the state-owned aviation will replace an aluminum-made control rod in the gearbox with a much tougher material and corrosion resistance . This increases the copter's fatigue tolerance as well as they pilots' control of the aircraft.

HAL officials said that the ALH had an excellent safety record, having flown more than 3,75,000 hours in the last two decades, and that metallurgical improvements to the gearbox's control rod is being carried out to improve the aircraft's performance.

The mean time for helicopter checks, which was originally 600 hours, has been reduced to 300 hours, and it has been learned that it has been further reduced to between 100 and 150 hours of flying.

Function of Control Rod in Helicopter Gear Box : Explained 

The control rod in a helicopter gearbox is a mechanical linkage that transmits the pilot's control inputs to the main rotor and tail rotor systems. The control rod is typically made of a strong, lightweight material such as aluminum or titanium. It is connected to the pilot's controls in the cockpit and to the main rotor and tail rotor gearboxes. When the pilot moves the controls, the control rod moves, which in turn causes the main rotor and tail rotor to change pitch. This change in pitch causes the helicopter to move in the desired direction.

The control rod is a critical component of the helicopter's flight control system. It must be strong enough to withstand the forces generated by the main rotor and tail rotor, and it must be able to transmit the pilot's control inputs accurately. A malfunction of the control rod can result in a loss of control of the helicopter, which can be a fatal accident.

Here are the specific functions of the control rod in a helicopter gearbox:

  • Transmits the pilot's control inputs to the main rotor and tail rotor systems.
  • Allows the pilot to control the pitch of the main rotor and tail rotor.
  • Enables the pilot to move the helicopter in the desired direction.
  • Is a critical component of the helicopter's flight control system.

Here are some of the common problems that can occur with the control rod in a helicopter gearbox:

  • Bending or breaking of the control rod.
  • Corrosion or wear of the control rod.
  • Binding or jamming of the control rod.
  • Looseness or misalignment of the control rod.
  • Damage to the control rod's bearings or bushings.

These problems can lead to a loss of control of the helicopter, which can be a fatal accident. It is important to have the helicopter's control rod inspected and repaired regularly by a qualified technician to prevent these problems from occurring.

New Delhi: A Noida-based private University, Galgotias has come under severe criticism after allegedly showcasing a china-made robotic dog at the India AI Impact Summit 2026 in New Delhi.

Social media users accused the university of purchasing a commercial robot from China and presenting it as its own creation at the summit.

Reports claimed that the university showcased the Unitree Go2 robotic dog, an AI-powered device available on Chinese platforms for Rs 2–3 lakh, under the name “Orion” during the event in New Delhi.

“So Galgotia university purchased a commercially available robot worth Rs 2.5 lakhs, called it their own and passed it off in the Delhi AI Summit as a part of their 350 crore AI ecosystem..I literally have no words left,” wrote ‘X’ user Roshan Rai, sharing a video in which a DD News reporter interviewed a university official about the robotic dog.

The viral post claimed that the robot closely resembles Unitree Go2, a quadruped robotic dog developed by Chinese company Unitree Robotics.

Screenshots attached to the post compared the robot displayed at the summit with the Unitree Go2 listing, priced at roughly 2,800 dollars (around Rs 2.3–2.5 lakhs).

According Unitree Robotics, The Unitree Go2 is widely used as a programmable quadruped robot for research, education, inspection, and development purposes, and is a common learning platform in universities and robotics labs worldwide.

Several users reiterated the claim.

Government of India funds for filing patents

Meanwhile, concerns were raised about alleged misuse of government funds.

User @sky_phd highlighted, “Galgotias University is once again in the spotlight. Under the guise of research and innovation, they are raking in plenty of money.”

The user claimed that the university took money under government funds, and wrote, “The Government of India provides incentive funding of up to five lakh rupees for filing patents.”

“To understand the patent filing process and the games being played with it, take a look at the list of top Indian institutions filing patents. All the Indian Institutes of Technology (IITs) together file only 803 patents, while institutions like Lovely Professional University, Jain Deemed-to-be University, Galgotias University, and Teerthanker Mahaveer University have filed more than a thousand patents each,” the user wrote, sharing a chart of patent filings by these universities.

“The basic international patent filing fee is $285–400. Through patent filings alone, these institutions are reportedly earning more than fifty crore rupees annually. However, while these universities file patents, they often do not pursue them further, and most patents ultimately do not get granted. This inflates filing numbers but does not reflect real innovation or recognized intellectual property,” the user added.

Another user pointed out about the selection criteria of the summit. The user questioned, “What exactly was the selection criteria for participation in this AI summit? .”

“Platforms meant to showcase India’s innovation should represent genuine research, original ideas, and credible institutions. So how did Galgotias University qualify to display a Chinese-made robot and present it as its own “innovation”? If true, this isn’t just embarrassing, it undermines the credibility of the entire summit and of India’s growing tech ecosystem. At a time when India is trying to position itself as a global AI and deep-tech leader, showcasing repackaged imports as indigenous innovation only damages trust. If we want the world to take India’s AI ambitions seriously, transparency and authenticity must come first,” the user added.

 

University clarifies after backlash

In response to the criticism, Galgotias University issued a clarification, stating that it “never claimed to have built the device” and that the robot was procured from a Chinese manufacturer for academic purposes.

“Let us be clear, Galgotias has not built this robodog, nor have we claimed to do so. What we are building are minds that will soon design, engineer, and manufacture such technologies in Bharat," the university said.

The university in its statement also pointed out that the Unitree Go2 is being used as a learning tool for students.

“From the US to China and Singapore, we bring advanced technologies to campus because exposure creates vision, and vision creates creators. The robodog is actively being used by students to test capabilities and explore real-world applications,” the university added.

University professor claims “it's developed by the Center of Excellence at the Galgotias University.”

In another video captured by DD News, a reporter showcased the Galgotias University pavilion at the India AI Impact Summit 2026.

At the pavilion, the reporter spoke with the university professor about the technology on display.

The professor introduced the robot, saying, “This is Orion. You need to meet Orion. It has been developed by the Center of Excellence at Galgotias University.”

She added, “I would also like to brief you about Galgotias University. We are the first private university investing more than Rs 350 crore in artificial intelligence and have a dedicated data science and AI lab on campus.”

“Orion has been developed by our Center of Excellence. It can take all shapes and sizes and is quite playful. It can perform small tasks such as surveillance and monitoring. It can even execute movements like moonwalks and somersaults,” she explained.

She also claimed that, “This is India’s first iOS lab in North India at a university, giving our students hands-on experience with cutting-edge technology.”

Reacting to the video social media users ridiculed the 350 cr rupees investment compared to the china made robo dog.

Past Controversies of the University

This is not the first time the university is in controversy. In May 2024, during the Lok Sabha elections, a video went viral showing students protesting outside the Congress headquarters in New Delhi against the party’s manifesto. The footage, captured by Aaj Tak, showed students struggling to articulate the purpose of their protest, raising questions about the demonstration’s intent.

Earlier, in 2017, students protested against the university management after being barred from appearing in exams due to low attendance, with allegations that fines were requested to allow attendance, a claim denied by the administration.
