Commercial drones typically rely on GPS for navigation, which works well when flying over buildings or at high altitudes. However, challenges arise when drones must maneuver between structures at low altitudes or suddenly enter crowded urban streets filled with pedestrians, bicycles, and vehicles. In such unpredictable environments, traditional systems often lack the ability to react quickly to unexpected situations. Researchers from the University of Zurich (UZH) and the Center for Robotics Research at the National Center for Scientific Research (NCCR) have developed an innovative solution called DroNet. This algorithm uses a deep neural network to analyze images captured by the drone's camera and determine appropriate steering angles. The system enables real-time obstacle avoidance and collision probability estimation, allowing the drone to make quick decisions while navigating complex environments. According to Professor Davide Scaramuzza from UZH, DroNet helps drones detect both static and moving obstacles and adjust their speed accordingly to avoid collisions. What makes this development particularly impressive is that the drones do not require advanced sensors—just standard cameras, similar to those found in smartphones. The breakthrough lies in the powerful AI algorithms that enable the drones to interpret visual data and respond appropriately in real time. One of the biggest hurdles in deep learning is gathering enough training data. To address this, the research team collected extensive datasets from dynamic urban environments, including cars and bicycles. Through this training, the drones learned to follow traffic rules, such as staying within lane markings and stopping when an obstacle appears ahead, like a pedestrian or another vehicle. Even more intriguingly, the drones were found to adapt to indoor environments, such as parking garages and office spaces, even though they were never explicitly trained for these scenarios. While there are still technical challenges to overcome, this technology holds great promise for applications like urban surveillance, package delivery, and disaster response operations. It marks a significant step forward in making autonomous drones safer and more versatile in real-world settings.
RCA Cables can be used to connect a variety of audio and video devices, such as camcorders, to TVs or stereos to speakers. Most high-end camcorders have all three RCA jacks, so the signal entering or leaving the device goes through three separate channels-one video and two audio-resulting in a high-quality transfer. Lower-end camcorders usually have only one jack, called a stereo jack, which combines all three channels. This results in lower-quality transfers because the signal is compressed. In either case, RCA cables transmit analog, or non-digital, signals. Because of this, they cannot be plugged directly into a computer or other digital device. RCA cables connect amplifiers to all sorts of devices.

Quality of RCA Cables
Several factors affect the quality, price, and performance of RCA cables:
Materials: The connectors on RCA cables are often gold, silver, or copper. As you might expect, the gold connectors are the most expensive. They're also better than silver and copper connectors at preventing oxidation, but not as good at electrical conductivity. The silver connectors are best for electrical conductivity with the copper cables coming in a close second and the gold cables falling far behind. Other suitable materials are nickel, zinc, and tin.
Cable Length: Cable length has a negative effect on signal quality. Buy a cable that is only as long as you need it to make the connection for the best signal quality.
Shielding: A well-shielded cable delivers a better signal than one that lacks robust shielding.
The other end of the cable: If possible, match the material used in the other end of the cable to the material used in the connectors. Don't match tin with gold or silver with gold. Those combinations can cause problems because of an electrolytic reaction.
