In Sunday's segment on Sky News Australia (Weekend Edition with Tim Gilbert) we looked at amazing tiny robots developed by the team at Northwestern University in Illinois, USA. They developed the smallest-ever remote-controlled walking robot — and it comes in the form of a tiny peekytoe crab. Just a half-millimetre wide, smaller than flea - the tiny robot crabs can bend, twist, crawl, walk, turn and even jump. The researchers also developed millimetre-sized robots resembling inchworms, crickets and beetles. The team used a laser beam to rapidly heat the robot. The heating and fast cooling creates motion.

In the very near future tiny robots, like these experimental creations, could assist in medical procedures like clearing clogged arteries, stopping internal bleeding or eliminating cancerous tumours. There’s a long, long way to go but this is exciting stuff.

SAMSUNG EXPERT RAW

If you have a new S22 Ultra you could be missing out on a massive photography update. Expert RAW is a ‘pro’ app that takes advantage of Ultra’s powerful camera array and ability to capture 16-bit images. It will allow users to unleash the full power of the S22 Ultra and other Samsung cameras. You can download it from the Galaxy Store. Other models supporting Expert RAW are: S21 Ultra and Fold3.

So if you’re doing a little photo editing, you’ll get some amazing results from Samsung’s latest flagship phone.

SONOS RAY SOUNDBAR

The Sonos Ray is a compact soundbar designed for smaller rooms, like a home office, bedroom or small TV/Gaming room. Key features are: - Optical input - Touch controls - TV remote sync - Apple AirPlay 2 - WiFi. I’ve just finished a full review on it and although small it packs a punch. Watch it here. It’s available from June 7 and costs $399 AUD.

SOUNDBOKS GO

If you want big sound on the go then the SOUNDBOKS GO is the ultimate speaker due to its insane volume and portability. It is very loud. Up to 121 dB. It weighs less than 9kgs , features two 72-watt continuous class D amplifiers, uses a removable battery and can be wirelessly linked to 5 SOUNDBOKS (Gen. 3) and Go speakers. It’s available now for $1099 AUD.

Keep an eye (ear) out for a review video soon.

In Sunday's segment on Sky News Australia (Weekend Edition with Tim Gilbert) we looked at Samsung’s S22 ULTRA. Is it the phone of the year already? The phone combines the best of the Note (S-Pen) and the best of the S-Series (Cameras).

Price: $1849 to $2449

We look at the productivity and image capturing capabilities of the ULTRA with plenty of test shots taken around Sydney Harbour at night. More testing is needed before we can say this will be phone of the year. The iPhone 13 Pro Max is holding its own at this point.

HAVE SMARTPHONES REACHED THEIR PEAK?

A lot of people are asking, “where’s the innovation?” when it comes to new phones. We discuss how significant under-the-hood updates are being missed my consumers. The new Samsung phones, like the new Apple devices, appear to be similar to recent versions. But the ‘unseen’ changes deliver big benefits when it comes to battery life and camera performance.

CHECK YOUR FIND MY IPHONE SETTINGS NOW

Tim called during the week about his daughter’s missing iPhone. We discovered that Find My wasn’t active but fortunately they located the phone later in the day. iPhones and Android devices have built-in location tracking but you must turn it on as soon as you setup your mobile.

We take you through the basics so you can always find your phone because some of the settings have changed. Third party apps are not needed.

"This is not a normal Ultra," says Garry McGregor from Samsung Australia. That was Garry’s response to my ‘statement’ that the Samsung Galaxy S22 Ultra is really a Note.

I have the ULTRA and PLUS models to test over coming days but in the video above you’ll see a quick explanation why the S22 ULTRA is more than the beloved Samsung Note and more than the usual S Series flagship.

Now we have the best of the Note with the best of the S series cameras.

Reviews coming soon so look out for them here and more on Sky News Weekend Edition with Tim Gilbert 7:15am Sunday.
