No, this is not a new optimistic robot that requires positive reinforcement. Stanford researchers have introduced YAY, a system that lets you yell instructions at your robot to improve its performance in real-time. This approach goes beyond standard programming, allowing for dynamic adjustments during tasks.

The robot gets better in real-time as it learns from the user’s instructions

Imagine your robot struggling to put a soft ball in a box. With YAY, you can simply shout “Squeeze the ball” and the robot will adapt its strategy. These corrective instructions are then stored by the system to enhance future performance. YAY allows the user to give shouted orders for complex tasks like bagging groceries, mixing fruits, and washing dishes. These tasks often require bimanual manipulation and handling soft objects like sponges, where precise control is crucial.

For example, if the robot drops a sponge while bagging groceries, you can shout “Move to me, then left” to guide it. The robot might need a few tries, but it will learn from the “go left” command to eventually succeed.

Beyond error correction, YAY allows you to adjust task details on the fly. Let’s say the robot grabs too much candy while filling a box. Shouting “Less!” prompts the robot to put some candy back. These human-issued instructions are used to fine-tune the system, leading to a reported 20% increase in successful task completion.

YAY’s architecture revolves around high-level and low-level strategies. The high-level strategy analyzes camera data and generates instructions for the low-level strategy, which controls the robot’s movements. Importantly, human voice commands override everything else, ensuring real-time correction.

The system also incorporates a feedback loop. Verbal corrections are recorded and used to refine the high-level strategy, making the robot less reliant on immediate voice commands over time. This allows for continuous learning and improvement even after basic training. YAY holds promise for creating adaptable housework robots that can respond to our needs and learn from our guidance. Let’s see how this evolves in the near future.

Samsung Electronics and Stanford University have announced that their collaboration has led to the development of an impressive 10,000 pixels per inch (PPI) OLED display. It will be useful for devices that offer close-eye viewing experiences, such as virtual reality.

This new 10,000PPI display is much better than what currently exists for virtual reality headsets. It is a major development given that most VR devices currently have what is called a “screen door” effect where the gap between pixels is visible.

OLED, a short form of the organic light-emitting diode is one of the most advanced technology displays available right now. It is used in several consumer electronic devices, including smartphones, TVs, etc.

To compare the newly developed 10,000PPI OLED display, most smartphones getting launched these days, including the premium ones, offer a pixel density of around 400 to 500 PPIs, which is less than one percent of what Samsung and Stanford have developed.

As for the technology, this new OLED tech uses films to emit white light between reflecting layers — one silver and another made of reflective metal with nano-sized corrugations. This allows specific colors to resonate through pixels and thus allows for much higher pixel density than RGB OLEDs on phones.

In laboratory tests, the researchers claim to have successfully produced miniature proof-of-concept pixels that offer higher color purity and a twofold increase in luminescence efficiency compared to color-filtered white-OLEDs.

In the quest to meet buyers’ yearning for smartphones with longer battery life, smartphone makers have developed several technological methods of battery manufacture. Smartphones are now packed with fast charging technology that delivers full capacity charge in just few minutes. But then, the rate of exploding phones seems to have increased as well, most times the phone’s battery is the culprit.

The case of the Samsung Galaxy Note 7 is perhaps the most notable smartphone till date to have been plagued by defective battery leading to the recall of the entire line. Although Samsung is yet to release the report of its findings on the exact cause of the Note 7 exploding incidence, local media allege that the report finds the battery as the cause.

However, there seem to be an end in sight as scientists at the Stanford University have published in the Science Advances journal that they have developed a battery that cools itself when it gets overheated. The battery is a lithium-ion battery built with flame-retardant triphenyl phosphate (TPP) inside a shell within the electrolyte fluid. The shell melts when the temperature reaches 150C (302F), releasing the chemical compound. The accompanying test result shows battery fires were extinguished in just 0.4 seconds.

Lithium-ion battery is the most popular battery that powers most gadgets, including smartphones and it gets affected by heat which turns it to a potentially explosive material. Attempts have been made in the past to incorporate TPP inside batteries without the shell and that have hampered their performance, so basically what they brought into the mix is the shell which they develop for the TPP compound inside the battery.

It is hoped that this development would lead to a break-through in lithium-ion battery manufacture which would eventually bring to an end cases of battery fire or explosions.
