2100 机器人传感器

几十年来，人类的想象力将我们带到了未来的一个地方，在那里人类可以创造出非人类的物品来执行他们平凡的任务。
例如，我们可以追溯到1900年，当时在小说“绿野仙踪”中介绍了砍伐树木的锡人。或者我们可以从太空时代家族杰森那里前进到20世纪60年代。
谁有很多机器人对手谁曾经在竞标。
让我们不要忘记着名的星球大战传奇，它在20世纪70年代以机器人明星C-3PO和R2-D2为背景。
今天，“未来”已成为现实。
我们现在生活在一个自动设备与真空吸尘器和微波炉一样普遍的世界。
我们人类的创造具有感知周围世界的天生能力。
我们可以看到它，品尝它，触摸它，闻它，然后听到它。
“机器人”必须能够在我们的世界中正常运作。
有许多传感器可以模仿我们感知世界的能力。
在那些传感器中，有几种不同的方式可以使设备“视线”。
“视觉”的顶级技术之一是飞行时间（TOF）。
该技术使用从设备发出的波形，例如声音或光。
记录该波形返回同一设备接收端所需的时间，以提供“飞行时间”。意法半导体最新推出的VL53L1（497-17764-1-ND）已推出该技术。
VL53L1芯片利用不可见（1类）激光发射器发出测量波形，利用SPAD（单光子雪崩二极管）接收它。
这提供了在高达4米范围内的快速50Hz测距频率。
通过使用包含NUCLEO-F401RE（497-14360-ND）STM32评估板的P-NUCLEO-53L1A1（497-17766-ND）扩展板，该芯片完全集成并易于连接。
通过使用专为其time of Flight设备设计的STMicroelectronics的GUI（图形用户界面），测试芯片也变得简单。
虽然这种产品最常见的应用是无人机（无人机），但可能性是无穷无尽的。
这些可能用于接近感应，自动驾驶车辆，免提等等。

For many decades the human imagination has taken us to a place in the future where inhuman objects would be created by humans to carry out their mundane tasks. For example, we can go all the way back to 1900 when a tin man who cut down trees was introduced in the novel “The Wizard of Oz.” Or we can go forward from there to the 1960s with The Jetsons, the space age family who had many robotic counterparts who were ever at their bidding. Let us not forget the ever-famous Star Wars saga which made the scene in the 1970s with the robotic stars C-3PO and R2-D2.
Today, the “future” has become nothing short of reality. We are now living in a world where autonomous devices are just as common as vacuum cleaners and microwaves. We humans are created with the innate ability to sense the world around us. We can see it, taste it, touch it, smell it, and hear it. A “robot” must be able to do the same to function properly in our world. There are many sensors that have been created to mimic our ability to sense our world. Within those many sensors are several different ways to give a device “sight.”

One of the top technologies for “sight” is Time of Flight (TOF). This technology uses a waveform, such as sound or light, sent out from a device. The time taken for that waveform to return to the receiving side of the same device is recorded to provide the “Time of Flight.” STMicroelectronics has advanced this technology with their latest addition, the VL53L1 (497-17764-1-ND).
The VL53L1 chip utilizes an invisible (Class 1) laser emitter to send out the measuring waveform and a SPAD (Single Photon Avalanche Diode) to receive it. This provides a fast 50 Hz ranging frequency at a range of up to 4 meters. The chip is fully integrated and easy to interface with by using the P-NUCLEO-53L1A1 (497-17766-ND) expansion board which includes the NUCLEO-F401RE (497-14360-ND) STM32 evaluation board. Testing the chip is also made simple by using STMicroelectronics’ GUI (Graphical User Interface) designed specifically for their Time of Flight devices.
While the most common application for this product is UAVs (drones), the possibilities are endless. These could potentially be used for proximity sensing, autonomous vehicles, hands-free, and much more.
