📌 TOPINDIATOURS Eksklusif ai: Disturbing Video Shows Man Jerking Robot Around by C

A video showing a robotics engineer violently yanking a humanoid robot around by a chain wrapped around its neck is making its rounds on social media, prompting fears that he may be accelerating the inevitable robot uprising.

Footage shows the robot stumbling helplessly as it struggles to stay upright. A different clip shows the human engineer kicking the robot’s torso in an apparent attempt to knock it down to the ground.

“This guy is the first one to die in the robot uprising,” one Reddit user joked.

Disturbing optics aside, it’s an impressive demo that shows how far the balance and resilience of humanoid robots have come in recent years. For instance, we’ve seen robots pulling off some gnarly kung fu moves and boxing each other in the ring.

The latest video was originally shared by Tsinghua University PhD student Zhikai Zhang, who has been developing a humanoid motion tracker system called Any2Track in collaboration with Chinese robotics company Galbot, the same firm that recently opened a robot-run bodega.

The system “needs to operate stably in real-world scenarios against various dynamics disturbances, including terrains, external forces, and physical property changes for general practical use,” Zhang and his colleagues wrote in the project’s documentation.

The team deployed a “two-stage reinforcement learning framework” to teach the robot how to adapt to these disturbances — such as being kicked or jerked around with a chain — on the fly.

The results speak for themselves. The Unitree G1 bipedal robot refuses to lose its footing, despite its human master’s considerable abuse, maintaining an impressive degree of balance and composure.

It’s not the only self-reported incidence of human-on-robot violence lately. A separate video, which went viral earlier this month, showed scientists at the Southern University of Science and Technology in Shenzhen, China, simiarly kickboxing a Unitree G1 humanoid robot.

The bot shrugged off the attacks with little effort — once again demonstrating that humanity would be doomed in the case of a genuine robot uprising.

📌 TOPINDIATOURS Breaking ai: ‘Dazzling’ innovation: Plastic bags turned into glowi

A plastic bag tossed away after grocery shopping may one day help detect toxic metals in drinking water. 

Researchers in Indonesia have unveiled a ‘dazzling breakthrough’ that transforms plastic waste into glowing nanomaterials capable of sensing harmful substances in water. 

Led by Dr. Indriana Kartini from the Department of Chemistry at Universitas Gadjah Mada, Yogyakarta, the work demonstrates how everyday waste can be upcycled into life-saving technology.

This study represents a shift in how we view plastic pollution. Instead of being a problem that clogs oceans and landfills, plastic could become the raw material for tools that protect human health.

From plastic waste to innovation

The world faces a persistent plastic crisis. Millions of tons of bags, bottles, and wrappers find their way into the environment every year, lasting for centuries without breaking down. Traditional recycling methods struggle to keep up, and much of this waste continues to accumulate.

The Indonesian research team took a different approach. Instead of recycling plastic into lower-grade materials, they reimagined it as a resource for advanced technology. By focusing on upcycling, they created a process where discarded polyethylene bags are converted into nanomaterials with powerful new properties.

“This is sustainability meeting smart science,” explained Kartini in a press release. “We’re not just reducing plastic waste—we’re turning it into a tool for public health.”

The innovation shows how science can tackle two global challenges: plastic pollution and access to safe drinking water.

The science of carbon quantum dots

At the heart of this breakthrough are carbon quantum dots (CQDs), tiny particles that measure less than a virus in size. CQDs have a special ability to glow when exposed to ultraviolet light. More importantly, they can act as sensors that detect pollutants at the molecular level.

Until now, producing CQDs has often required expensive or toxic raw materials, making them impractical for large-scale use. The Indonesian team, however, used waste plastic bags as their starting point. 

They combined modified pyrolysis with hydrothermal treatment, and with less than 7 percent hydrogen peroxide, they transformed the polyethylene into functional CQDs. The entire process took only 10 hours.

The results were impressive. The CQDs had a quantum yield of 10.04 percent, measuring how brightly they glow. They also showed stability when exposed to UV light, high salt levels, and long-term storage conditions. This stability makes them reliable for real-world applications.

Detecting toxic metals in water

The most striking aspect of these plastic-derived CQDs is their ability to detect metals, particularly iron ions (Fe³⁺), in water.

Their surfaces contain oxygen-rich chemical groups that can selectively bind to these ions. This interaction allows the particles to act as precise sensors for contamination.

In testing, the CQDs achieved a detection limit as low as 9.50 micromoles and displayed a near-perfect correlation of R² = 0.9983 when measuring iron concentrations. Such accuracy shows the potential for these nanomaterials to be used in water quality monitoring.

Portable, affordable, and easy to deploy, these sensors could provide valuable support in communities where access to sophisticated laboratory equipment is limited.

Iron contamination is a widespread issue in drinking water, and being able to test for it quickly could help prevent health problems.

Toward a circular economy

The implications of this research go far beyond laboratory experiments. It represents a practical example of a circular economy, where waste is not discarded but transformed into valuable products.

The project demonstrates how science can convert an environmental burden into a technological asset by turning plastic bags into sensing tools.

The approach could inspire new industries focused on eco-friendly nanomaterial production. It also highlights opportunities for low-cost environmental monitoring solutions in regions facing waste management and clean water challenges. For Southeast Asia in particular, the work provides a model for how green chemistry and innovation can intersect.

Universitas Gadjah Mada is positioning itself as a hub for sustainable science. This project adds to the growing recognition that Indonesia can contribute not only to solving local problems but also to providing global solutions.

The study was published in Carbon Research on July 3, 2025.
