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. https://t.co/jKxtlYEYIQ

"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 ...

My dad sent me this view from my childhood room in Portland. It hit me that we have been wasting our collective intelligence in tech optimizing for profits and ad clicks.

Forest surveying is an essential metric for the $500 bn global forestry industry. That’s why Trefo is introducing a novel UAV-based approach to make surveying cheaper, faster and more accurate.🌳 Read more about our investment in Trefo here: https://t.co/xc2ZBLZpzk

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
