How Do You Get Into Robotics?

Chosen Reject asks: "With Voyager I passing the 100 AU mark, and the Mars Rovers continuing to work longer than expected, there's been a lot of talk about robotics. There are cars that can park without humans, the DARPA Grand Challenge, the Autonomous Underwater Vehicle Competition, and even the X-Prize. NASA has the pros, the others have all levels of amateurs, but where does a newbie go to learn about robotics? Obviously I can't start out with the next Mars Rover, but where do I go to learn how to make a simple robotic arm that can hold my can of Root Beer?"

For recreational robotics - building simple stuff as a hobby - something like Lego Mindstorms is a very good way to get introduced to the field. Then you can start looking at experimental controller boards like a Basic stamp, self-contained single-board Linux machine or other small development system and go on building your own hardware from components.

Just realize that robotics encompasses several disparate fields - various software disciplines, electronics, electromechanics, wood- plastic- and metalworking and so on - each one of which is more than a full academic field in itself. Don't expect to develop real expertise in all areas; find the areas in robotics that especially fascinate you and focus on that.

For academic or industrial "real" robotics, expect to first take a Masters or equivalent in any of the disciplines you need (some areas could be mechanical engineering, control theory, computational neuroscience, even psychology), then widen your general knowledge and deepend your area of expertise through a good PhD program. After which, of course, you'll find few real research positions and a lot of very qualified applicants - but that's a different issue :)

Bear in mind how little is going on commercially

There are academic programs, but the US robotics industry is tiny. I have a slide I use in talks; it compares total spending on robots, mobile robots, and ringtones. Ringtones are far bigger.

Robot R&D in Japan is serious, but in the US, it's the same old academic groups grinding away. The number of US commercial companies shipping products in the mobile robot space is very small, as is number of units shipped. Above the Roomba/toy level, there just aren't any volume applications. This seriously limits job and business prospects. There's a market in teleoperators for bomb disposal applications, and the machinery developed for that is quite nice, but it's not autonomous.

Even industrial robotics and factory automation is declining in the US. With manufacturing moving offshore to low-wage countries, the end of union labor, and a huge supply of illegal immigrants, plants are less automated than they were twenty years ago. The original Macintosh had less assembly labor in it than today's PCs. I can't recommend a US career in manufacturing engineering today.

Robot hardware is better than ever. The Lego Mindstorms stuff is primitive, but around $1000, things get quite good. Check out RoboNova. Further upscale, see Mobile Robots, Inc.

The theory is getting better. Vision is starting to work. Planning actually works in the real world now. Adaptive control and learning finally work. There's enough CPU power to do hard stuff in real time on cheap hardware. Much is technically possible. But the market isn't there.

I ran one of the DARPA Grand Challenge teams. That didn't really lead anywhere. The two best young people we had are doing very well, but not in robotics. One is running a hedge fund and one is working for an offshore derivatives fund. Of the older people, one is running a big web server farm, and one has retired. If you understand all the practical stuff and all the theoretical stuff to operate at that level, you can do very well at other things. But the payoff isn't in robotics.

This field needs a killer app.
