Hardware took the spotlight at today’s Y Combinator Demo Day, reflecting a major shift of the accelerator beyond the cliche mobile app startup. Out of the 50 companies from the Summer 2015 batch that demoed on the record today, 20 featured hardware. What was formally the Demo Day lunchroom has become an expo hall for all manners of robots and gadgets.

Tomorrow, another 50 or so startups will present. Soon, we’ll have our selections made for our favorites. But for now, here’s a look at all 50 that strutted the stage today:

TeaBOT — An automated beverage vendor

TeaBOT is a robot that makes grab’n’go tea. You enter up to three types of its dozen teas, pay via iPad or credit card, and the bot automatically mixes you a hot cup of tea. The company says the bots can earn $100,000 a year. The startup licenses the TeaBOTs to retailers and colleges, and keeps 85% of the revenue, while giving the client 15%. With the tea and grab’n’go food and beverage markets growing, TeaBOT could absorb a ton of spend if it can convince businesses it will make them more than anything else they could do with 10 square feet of space. Read our full TechCrunch post about TeaBOT.

Circle Medical — The Doctor That Comes To You

Circle Medical will send a primary care physician to your house to do everything you could get done at a doctor’s office, from checkups to blood tests. Users just scan their insurance card, and Circle Medical tells them which services they’re qualified to receive for free. Because 75% of doctor visit costs go to the office, Circle Medical can pay doctors $140 an hour while earning $60 for itself. It already has three full-time doctors in SF. To acquire users, it has a workplace program where employers block out time for multiple employees to see a Circle Medical doctor. It’s been able to gain users for just $5 each this way. That could let Circle Medical make health easier while breaking into the $300 billion a year primary medical care market. Read our full TechCrunch post about Circle Medical.

Wheelys Cafe — A full-service cafe on a bike

2 billion cups of coffee are served per day but one of the main costs is rent. Wheelys lets entrepreneurs avoid these costs by putting a full coffee, juice, and snack-dispensing cafe on a bike-drawn cart. The cart costs just $3,000 and can be pedaled between the best spots to sell, while “a Starbucks is really heavy” says the co-founder. Parked outside a Starbucks, the Wheelys CEO served 210 customers by lunch while the Starbucks had only served 148. Beyond selling the carts, Wheelys also sells the supplies. Eventually, it wants to build a network of the carts where people can pay with an app like Uber. Read our full TechCrunch post on Wheelys.

Transcend Lighting — Efficient Indoor Grow Lighting

Indoor agriculture, with its enhanced control over quality, is growing quickly, but the second biggest cost to farmers is lighting. Transcend has invented a patent-pending photosynthetic LED light that’s 35% to 50% more efficient than competitors. “And no, it’s not just for pot…although we do quite well in the cannabis industry”, the co-founder says. Traditional tomato and lettuce growing are its core business. It saved $150,000 for a farm that was planning on just $120,000 of profit, more than doubling their success and making the lights return their cost quickly. Transcend could let more food be grown inside for a lot cheaper. Read our full TechCrunch post on Transcend Lighting.
