HomeTech Review: Roborock Dyad Air Wet Dry Vacuum Cleaner

Sunday, December 31st, 2023

Most home vacuum cleaners are expert at cleaning up dry dust and dirt. The Roborock Dyad Air comes in useful when you have a wet mess on the floor – a cracked egg, spilt cereals with milk, overturned bowl of noodles in soup etc.

Christmas present for the wife. No more stress when the egg drops onto the floor or the kids spill soup noodle on the floor. Roborock Dyad Air wet dry vacuum cleaner.

For regular vacuuming and mopping of the floor of the apartment, I depend on a robot vacuum which is able to accomplish the job well and without complaining – regardless of how frequently or how many iterations I put the robot through its paces.

Occasionally, the wife drops an egg on the kitchen floor, or the kids spills some cereals with milk, or I spill some noodles with oily soup on the floor.

That’s when we have to roll up our sleeves, get on all fours and clean up the mess manually.

You can’t use a dry vacuum on the wet mess because you don’t want the vacuum to suck up the wet egg white and yolk into the dust bag and goo up the parts between the vacuum head and the dust bag, and have food remnants rotting away inside the dry vacuum.

And you can’t mop up manually until after the solid debris – the shells, cereals, noodles – have been picked up and removed.

That’s why I got my wife the Dyad Air wet dry vacuum.

Overview

Technically the Dyad Air is just a wet vacuum/mop – it wets the roller mop (and therefore the floor surface) with clean water (you can add a mild Roborock detergent) and sucks up the entire mess – solid debris and wet spills – into the dirty water tank of the Dyad Air.

Tech Focus – All about automotive lidar

Friday, December 22nd, 2023

From its use in metrology and topography, lidar (light detection and ranging) technology has come a long way to quickly become one of the key technologies in autonomous vehicle (AV) advancements. Chaimaa Aarab from Keysight Technologies gives you the lowdown on lidar for AVs.

As automakers progress with real-world testing, it's clear that next-generation sensors offer intriguing features but differ from the silver bullet many thought they'd be at first.

As automakers progress with real-world testing, it’s clear that next-generation sensors offer intriguing features but differ from the silver bullet many thought they’d be at first.

Without driver/human inputs, AVs require sensors and computers to work together to read the road and surrounding environment.

Most advanced driver aids in the world today use a combination of radar (microwave) and sonar (sound) to warn about unseen threats and help stop a vehicle before a collision occurs.

Lidar can perform similar functions, developing an image of the environment around it while still representing the best option for AVs to see the light.

Lidar technology in automotive

The automotive industry is undergoing an existential transformation with autonomous driving (AV) and advanced driver assistance systems (ADAS).

To achieve a fully autonomous driving experience, sensor fusion is positioning itself as the key enabler in the automotive industry.

While sensor fusion focuses on software algorithms combining the data collected from cameras, radar, and lidar to obtain meaningful decision-making information, data quality is paramount.

While there’s still a long way to go in mimicking the human senses and brain for level 5 driving automation, sensor fusion is a further step in that direction.
