Cool tech we're watching.

A pocket flying camera — a drone that folds down small enough to toss in a bag, so you can get an aerial shot without hauling gear.

A robot vacuum with a robotic arm attached, so the machine that already sweeps your floor can pick up a few things too.

A modular PC — one small computer core that drops into different bases, so the same machine works at the desk or on the move.

Heated massage slides you wear on your feet — a warm-up and mobility tool made with Nike, built for recovery between events.

A solar-powered hat with a small panel along the brim, so a long day outside can top up a phone or a light as you go.

A wrist thermostat — it warms or cools your wrist to make you feel comfortable, instead of turning the whole house up or down.

A stringless smart guitar — it teaches you songs and shows you what to do next, so learning an instrument feels less lonely.

An automatic foam roller — it rolls itself along your legs and back, so the part of recovery nobody enjoys happens on its own.

A MagSafe AI camera for iPhone — it sticks to the back of your phone and follows you around a room so you can film yourself hands-free.

An auto-fade hair clipper — it does the fading for you, so a good haircut doesn't depend on a barber's hands.

A tongue-controlled touchpad — it sits in your mouth and lets you drive a phone or computer without your hands, which matters for a lot of people.
