Check out our video on long-range GPS-denied under-canopy autonomous flight! Our quad can fly 800 m autonomously in very challenging conditions while performing real-time semantic SLAM. Great work by Xu Liu, @guinardari, @chenstew, @vijay_r_kumar, et al. youtu.be/Ad3ANMX8gd4

"The vast forests of our national parks and timber farms have countless trees, but you can’t put 'countless' on the paperwork."
💯%! That's why our drones map forests with unprecedented accuracy speed, while helping foresters make huge efficiency gains.
Thanks @TechCrunch

Today I am leaving the US.
With my family we are exploring a new life in the south of France.
I’ve been in the US for more than 16 years. I earned my citizenship & experienced many ups & downs. But I am grateful. The US was good to me in many ways ...

There is one hour left to vote for the @Wharton @WhartonEntrep Startup Challenge crowd favorite. Throw a vote to MAR Designs (@rmli_ @AriellaMans & me). We are working to improve the lives of kids with cerebral palsy with a novel orthosis.

GRASP is building telemedicine carts to reduce risk to @Penn Medicine specialists. The carts will replicate the functionality of commercially available carts but at a lower price and with off the shelf parts. We're deploying later this week. #coronavirus

Reading "Zero to One" by @peterthiel and came across his comparison of airlines vs Google. Anyone else think that the self driving car industry will end up like the airline industry (highly competitive)? Creates a lot of value but hard to capture it. @zerotoone @selfdriving
