How can unmanned aerial vehicles accelerate their development in the warehousing and logistics industry
UAV is a kind of unmanned autonomous vehicle (UAV), which is basically a flying version of robot. Although unmanned aerial vehicles have gained a reputation for their flexible use outdoors, they are also beginning to expand their availability indoors. For example, corvusrobotics, a start-up in St. Louis, is providing drone solutions for warehouse inventory and facility inspection at logistics and manufacturing facilities. Flyability, another Swiss start-up, also provides indoor aerial inspection drones for inspecting confined spaces. Indoor drones are generally smaller than outdoor ones. In addition, they provide better accessibility and can scale different heights, which is not always possible for crawlers and ground robots (robots moving on the ground). Because of their autonomous flight characteristics, they have more versatility and greater tolerance to the unknown in the environment. In addition, in addition to inspection and monitoring purposes, indoor UAVs are also very helpful in vlog, large UAV training tools and entertainment purposes
market scope and use
a report in 2019 mentioned that by 2027, the UAV market will grow by $29billion, with a compound annual growth rate of nearly 20%. The report also points out that indoor unmanned aerial vehicles provide some major advantages, such as less dangerous tasks such as climbing (crawler), and rapid return on investment due to controllable hardware acquisition costs. Compared with outdoor UAVs, indoor UAVs are also easier to be recognized. The main industries of these gadgets are warehousing and logistics, where they can help with inventory management, indoor and internal logistics, as well as inspection and supervision. When the two kinds of bio based epoxy obtained earlier this year reached UL (9) 4 V0 industrial flame retardant level, digitalaerolus developed the world's first indoor unmanned aerial vehicle (aertos120 UVC), using C-band ultraviolet (UVC) light. This kind of UAV is specially manufactured to combat the spread of covid-19 (sars-cov-2) virus, and the disinfection rate is 99%. A thus realizing real benefits ertos120 UVC can stably fly in the building and disinfect the area, thus reducing the chance of front-line workers being infected. Studies have shown that when the wavelength is 265nm, UVC light can damage the RNA of the virus
because GPS can not work in most buildings today, most indoor UAVs use image recognition technology to fly autonomously. For example, last month, Japanese researchers developed a single camera machine vision algorithm that allows a lightweight hovering robot to guide itself by identifying and interpreting reference points on the tile floor. Chinthakapremachandra, the project leader and associate professor of electronic engineering at 60 ~ 100hrf University of Tokyo Zhipu industry, said that because the GPS signal is too weak to penetrate most structures, indoor UAVs usually rely on visual environment cues. The goal of his research team is to design a navigation algorithm as simple as possible, allowing the use of a small, inexpensive microprocessor. The research team used raspberrypi3, an open source computing platform that weighs about 45 grams. Their prototype has only a low resolution downward facing camera - only 80 × 80 pixels. "Our robot only needs to distinguish the direction of motion and identify corners. From there, our algorithm allows it to infer its position in the room and help it avoid touching the wall.
another method used by indoor UAVs is structural motion algorithm (SFM) 。 SFM calculates the relative relationship between cameras according to the images collected from different positions, obtains parallax, and realizes the restoration of three-dimensional space. Even the elios2 UAV of mobility uses collision tolerance and airborne lighting, so that the UAV pilot can safely and efficiently operate the UAV without any external light source. Elios2 also has seven visual stability sensors to help it achieve GPS free stability. One of flyability's customers, Veritas, used elios2 to inspect ballast tanks on one of its cargo ships during three 10 minute flights. This is an incredible feat, because the same inspection requires three to four inspectors to use ropes, oxygen monitoring equipment and extensive safety equipment without drones
although indoor UAVs have great potential, there are still some challenges that need to be solved first. Indoor UAV must have self-awareness and avoid moving objects by itself. It needs to be upgraded to a better stability system to improve stability in spaces with fans or indoor airflow. Through these improvements, the indoor UAV will be one step closer to achieving full autonomy and functional state
