Even with a ton of drone regulations, there was a ton of innovation at the SUSB Expo

An MLB Company representative shows the company's Super BAT's camera gimbal system to an audience member during the SUSB Expo, in San Francisco, CA.

It's not very often you get the chance to watch the birth of a multi-billion dollar industry firsthand. But if we are to believe the Association for Unmanned Vehicles and Systems International (AUVSI) economic report, which estimates the unmanned aviation industry should reach $82 billion by 2025, that's exactly what happened at the first-ever small business expo for unmanned aircraft, the SUSB Expo, in San Francisco.

"It's like being in Steve Job's garage," said Agriflight's Bruce Parks, as reported by Robohub's Andra Keay.

Why Google's executive chairman is totally wrong about "drones"

Eric Schmidt

In a interview published in the Guardian newspaper on Saturday, Google Executive Chairman Eric Schmidt called for tough regulations on unmanned aircraft systems, commonly called drones.

The BBC reported that Schmidt said:

"How would you feel if your neighbour went over and bought a commercial observation drone that they can launch from their backyard. It just flies over your house all day. How would you feel about it?"

Schmidt went on to suggest that only governments should have access to unmanned technologies:

"It's got to be regulated... It's one thing for governments, who have some legitimacy in what they're doing, but have other people doing it... it's not going to happen."

"Drone" over SXSW provides aerial view of NASA's shiny new space telescope

Unmanned aircraft made their South By Southwest debut this year, and prominently so. A session with Chris Anderson, former Wired EIC turned full-time head of 3D Robotics, and Ryan Calo of The Center for Internet and Society at Stanford Law School, among others, included a discussion on the many commercial uses for UA.

On the same day, at the Palmer Events Center, near a full-scale replica of NASA's James Web Space Telescope, another panel was being held that featured a live demonstration of an unmanned system.

A map of all the drone laws in the United States.

The ACLU recently published on its technology blog a list of 28 states that are pursuing regulations for unmanned aircraft systems, or UAS. They're more commonly referred to as "drones," and in fact many of the proposed laws use that exact word.

I dug further to find out what lawmakers are actually proposing. You may click on individual states in the above map to learn more about specific legislation.

Out of the 28 states, 14 are proposing limitations only to law enforcement. In most cases, proposed legislation would make it illegal for law enforcement to use an unmanned aircraft without a warrant.

Some also call for evidence obtained from a "drone" to be destroyed after a specified period. A few ban any government entities from using the technology altogether.
