Welcome back, Dr Gregory Charvat!
- List of past appearances
- Greg was an easy hire as he’s literally the “guy who wrote the book” on the subject, “Small and Short-Range Radar Systems”
- He is currently the CTO of Humatics
- Greg got started with project based learning – coffee can radar
- He returned and did a stint as a visiting professor with Ramesh Raskar. They developed a camera that allows you to watch microwaves propagate
- Fields and waves vs optics people
- Optics make some approximations that EM people can’t
- Phase coherent processing
- Butterfly Network was a company that developed an Ultrasound module on a chip
- Jonathan Rothberg
- They first developed an ultrasound tomography (similar to a CT scan) but the cost of goods was too high.
- MEMS based sensors, instead of the traditional way of making ultrasound transducers with high frequency quartz.
- Lots of analog parts onto the chip, the hard part was making them manufacturable.
- Greg moved on when funding was secured
- He then went to Hyperfine, another company founded by Jonathan Rothberg but still in stealth mode.
- Built the first machine in 100 days
- Built the next in 4-5 months
- Greg is learning how to hire people
- It costs more to over-analyze than to just start building (sometimes).
- Greg wants to take back the term “Technology”
- You should do a tour in defence because the unlimited budgets leads to cutting edge work.
- Greg moved onto his current role as CTO of Humatics
- David Mindell was a professor at MIT. He also wrote a book called Digital Apollo about the flight computer.
- The Humatics system is a short range, super high precision GPS using microwave transceivers.
- “That should be a piece of cake”
- David worked for Bob Ballard, who is known for discovering the Titanic
- ALVIN
- HDDG talk about deep water by Nic Bingham
- Center for marine robotics conference
- You can see what they see at the control center live via Nautilus Live
- GPS won’t penetrate the water
- Acoustic based navigation system
- Perfect recreation of the titanic
- Gary Cohen does business stuff, James Kinsey is the robotics person
- Ultrawideband company for sale (Time Domain). Didn’t buy the company right away (they did later)
- Demo’d it at MARS – Machine and Robotics Symposium
- Kiva Robotics told Jeff Bezos about the demo
- Build proto in 4 months
- It is centimeter accurate precision out to 4 nines (99.9999% of the time). It has a coverage area of 500m.
- SLAM
- The problem is that things change in a manufacturing scenarios
- Currently there are humans in the loop
- The robot is pinned to a line, which is an absolute system
- For the forthcoming millimeter precision device, it will cover 10 m total
- This will be used for “virtual fixturing” or said another way, “Where does stuff live in the real world?”
- Time of flight uses impulses
- Startups as a career path
- Interested in learning more and/or joining their the teams discussed here?
