We're working on riderless and balance-assisted bicycles and motorcycles. We're working to ship our flagship bike and we're about to launch a balance-bike for kids that helps them learn faster and sets up virtual bumpers whil

Regen will usually only gain you 3-5% total range, most of the power from biking is dissipated as heat through aero drag, even if you're biking up and down hills. Source – my company exclusively does ebike research and development.

This should be the new standard for ebike charging, or all personal EVs like scooters and EUCs.

Ebikers naturally start taking routes that optimize for safety and enjoyment over avoiding hills. It would be cool for Strava or Goog Maps to detect ebikers (easy to tell from speed vs road grade) and weight their routes more heavily in dec

I also grew up in NZ idolizing Faraday. I feel sad to see obviously smart and passionate folks like this with deep technical interests end up in venture so young.

Moreover, the kind of builders you want as an early stage startup are almost certainly not the type who would be hired guns for this kind of VC.

You joke, but I’ve kicked around the idea of bike tunnels with collimated air blowing down them at 20mph to make riding at that speed more comfortable, and make loitering uncomfortable. Microautonomy might make that feasible.

This is bizarre, I’m in non-car autonomy but I talk daily with car autonomy folks. Everyone has been expecting a consolidation of companies through acquisitions but drive.ai showed us that it’s probably not going to happen. At The Informati

I've done this math before and it's not encouraging. Global carbon fuel burning is more than two cubic miles annually. A billion trees will capture about a trillion kgs of carbon over 10-20 years, but yearly we're burning abo

I did undergrad at UW, several of my classmates did grad work on LIGO and were on the gravity wave teams when they had their first detection. Amazing what timing can do for a career. I visited Hanford LIGO in 2012 before the detection, real

I think we all know what the quote is about even though it's not an actual Ponzi scheme, it's just fraud. Another good reminder to question everything, especially group wisdom.

"How would you ensure having the exact same starting conditions each time?" is the best question in that thread, and this was the biggest challenge for us in training our bikes to balance using a NN. Bikes are hard because they&#x

I've lived in a ~250sqft 1940's era wood train car for the past 9 years, with my wife and now a newborn. It is doable if you enjoy the constraints and how it affects your decision making. I live about 5 miles from Seattle in a ver

I use this to send messages to the agent that won't be recorded in the transcript because I delete it after typing it. Not sure if it has gotten me better results from the agents but it's fun to do.

I tweeted at him to ask him what size lens and sensor he has so I could estimate how much energy/flux was hitting his sensor. Anyone have an idea of how many lidar it would take to saturate an area and make distance measurements useles

I've been following these guys for a while and I really like their approach. In our lab we've done a lot of work to improve control of cheaper BLDC motors (low gearing) to mimic human control and compliance, and these guys are usi

I've noticed a surge ofex-uber folks looking to angel invest having been popping up in the past few months. I'm excited for this IPO purely for the money that will be invested in transportation this next year.

Awesome result, hopefully we'll see a video of it in action and more information of thrust to power ratio. Very cool.

I use quaternions at work (AVs) and used them in physics and astronomy in school. The math he's talking about is darned close to the math done behind the scences with quaternions, it's just easier to grasp because it has visual re

Localizing the sound isn't just a matter of hearing a phase shift between your ears, you also have some 'knowledge' about how sound moves in a room, how your ears change the sound, and what frequencies will be more prominent

Sorry no, I'd have to dig up my notes from the interview and I'm slammed working on my startup. You don't wanna move to the west coast? You like bicycles and robots perchance?

I interviewed, I've talked to several other robotics companies that interviewed for S18. Absolutely dumbfounded that none of them made it, some of these in the batch seem like they could never be worth $10b.

I wonder what this would have felt like since it would not stay humid for more than a few minutes after it stopped raining. Humidity of 100% above 90F feels like 130F+ so this must have been wild.

My company is working on self-delivering bikes so citylab always pops up in our network, they do some great work. Not quite sure why they are so prolific.

I started commuting by ebike full time last year and now when I do drive in traffic I notice how crazy my road rage gets. I get so upset at the insanity of sitting in this giant box that is 25x my body weight as I crawl in orderly queues wi
