As a budding robotics start-up in a SAAS-crazy Vancouver, we were thrilled to hear the good news coming from the Y Combinator Demo Day today. Out of the 50 companies featured in the Summer 2015 batch, 20 were hardware start-ups.

Don’t get us wrong. We give kudos to all start-ups who put in the blood, sweat and tears required to get their business off the ground. But the hardware game is different, and requires different tools that add a whole other set of roadblocks to the challenge.

Here’s a quick rundown of some of the hardware startups featured in today’s Tech Crunch article. A couple of them are making us hungry… a couple others have us planning a container garden.

Auro Robotics – self-driving shuttles for closed campuses (also, check out this development out of Waterloo)

Flirtey – a drone delivery company that beat Amazon to the punch

TeaBOT (pretty self explanatory)

BistroBOT – a sandwich making robot that we would love to have here at our office

Ohm – a car battery that never dies

Bodyport – a smart scale that measures your heart disease risk

Seva Coffee – an automated coffee maker that grinds and roasts pre-roasted beans

Transcend Lighting – patent-pending photosynthetic LED light for indoor growing

Luna – a smart mattress cover that measures your sleep

Nebia – a water efficient shower

Click & Grow – a low-maintenance container plant

Oolu – a subscription service that provides and maintains solar energy in West Africa
