Researchers at the University of Zurich have developed a new quadcopter drone equipped with a new camera and customized algorithms that cut the reaction time down to just a few milliseconds- enough to avoid a ball thrown at it from a short distance.

Drones can do many things, but avoiding obstacles is not their strongest suit yet, especially when they move quickly.

Although many flying robots are equipped with cameras that can detect obstacles, it typically takes from 20 to 40 milliseconds for the drone to process the image and react. But, this research has addressed this challenge by developing a drone capable of avoiding objects from a three-meter distance and traveling at 10 meters per second.

In their tests, the researchers used a basketball to measure the efficiency of the new drone. They throw the ball from a short distance at the drone, which managed to avoid it. The results of the experiments were announced in the Science Robotics journal.

According to a report released by the University's website on March 19, the new drone will use the so-called "event cameras" after the researchers invented new algorithms that work with it.

Traditional video cameras, such as the ones found in every smartphone, work by regularly taking snapshots of the whole scene. This is done by exposing the pixels of the image all at the same time. This way, a moving object can only be detected after all the pixels have been analyzed by the on-board computer.

Event cameras, on the other hand, have smart pixels that work independently of each other. The pixels that detect no changes remain silent, while the ones that see a change in light intensity immediately send out the information. This means that only a tiny fraction of all pixels of the image will need to be processed by the onboard computer, therefore speeding up the computation a lot.

Nintendo has announced a June 5 launch date for its latest gaming console, the Switch 2, which will introduce interactive chat and screenshare functions to connect gamers.

At its 60-minute Nintendo Direct presentation, the company revealed a more vibrant display on the Switch 2, a larger screen and several games that will launch with the console.

Central to its updated system is a new “C” button on its Joy-Con controller, which will launch a new “GameChat” feature that allows you to “communicate with friends and family while playing a game,” and let you share your game screen with other players. A built-in microphone will also allow you to chat with other gamers, The AP reported.

Perhaps the most contemporary function yet for the Switch 2 is the ability to use the Joy-Con controllers like a computer mouse. The developer displayed multiple ways to use the new function in games, such as angling a club in a golf game.

Wednesday's presentation led off with an extended look at a new Mario Kart game that saw in-game characters doing flips, tricks and rail grinds. The developer also unveiled a new James Bond game, dubbed Project 007, revisiting a classic Nintendo 64 console hit revered by many first-person shooter game fans.

The new console will be backwards compatible — able to play physical and digital Switch games — but users will need to purchase a new type of SD memory card for the Switch 2. The presentation revealed that normal SD cards will not be compatible with the system, but data from the original Switch can be transferred to the new console.

Nintendo plans to host “Switch 2 Experience” events in several countries, where gamers can get a hands-on experience with the new system. Those events are planned for cities such as Los Angeles, New York, London and Paris beginning this month.
