Comment: Tesla Cars are Grid Storage (Score 2) 151

If Tesla makes the cars' power bidirectional, the excess capacity of cars plugged in for recharging (essentially) becomes a grid-connected battery itself. I recall seeing homebrew electric cars used as "generators" during brownouts a few years back. Tesla could do this on a massive scale using individuals' cars -- and pass some of the gains (peak power) back to the car owners.

Back in 2009, the same researchers had this hand doing all sorts of crazy dexterous motions... dribbling, pencil flipping, throwing & catching, etc:

Actually, the fully-loaded cost for a PhD student is $75k-$80k / year (ie the amount charged to a faculty member's grant). You have to remember, PhD students' tuition is usually incurred as part of the cost since they're working in exchange for (1) a minimally-viable living stipend and (2) fully-paid tuition.

We had two PR2's in our lab (Georgia Tech's Healthcare Robotics Lab). There were ~2 people working on each at any given time.... so the $$ makes sense. And the PR2 was a great platform!

There are a lot of hard engineering problems to overcome, even if the system was efficient... For example, a second resonant load nearby severely de-tunes the system, antenna mounting considerations are of supreme importance (good luck putting one on a laptop full of metal), and antenna alignment is absolutely crucial! The whole WiTricity concept might be sound in theory, but the engineering challenges are monumental.

That's kind of a funny title to see this on the front page of /. on the same day that we have one of the biggest (robotics) hardware announcements of the decade: Rethink Robotics just announced their $22,000 humanoid robot. The visionary behind Rethink is Rod Brooks -- former MIT CSAIL director, co-founder of iRobot, etc etc. This new arm is a 10x drop in price compared to other comparable platforms (eg. Kuka, PR2, Barrett, Meka, ABB, etc). Hardware is definitely not dead... but perhaps "PC hardware" is...?

IMO, the "big deal" in inflatable robots comes from OtherLab... They've built giant (ridable!) inflatable robots and inflatable robot arms with insane power to weight ratios. We did a special on them at Hizook a while back: The OtherLab project is also part of the same DARPA program (M3) that spawned the iRobot inflatable arm.

This is a common misconception. In academia, "humanoid" will usually refer to a robot with _some_ humanoid features (eg. two arms). If you look at the "Humanoids" conference, you'll see that there are a healthy mix of legged and wheeled designs. So I thought specificity was good in this case...

Uhm... I'm pretty sure that every single one of the Intuitive Surgical DaVinci robot workstations are 3D for the operator -- and we all know that hundreds of surgeries are performed with these every day.. In this video of researchers playing "Operation" (the board game) with a DaVinci robot, you can see the operator console with separate eye pieces to give 3D effects. I personally got to play with a DaVinci at IROS (robotics conference) last year, and the operator console was definitely in 3D -- though the observer consoles are just normal 2D TVs. I was told that this had been standard for a _long_ time.

HizookRobotics writes "The official announcement should be out very soon, but for now has unofficial, preliminary details based on notes from Dr. Gill Pratt's talk at DTRA Industry Day: The new Grand Challenge is for a humanoid robot (with a bias toward bipedal designs) that can be used in rough terrain and for industrial disasters. The robot will be required to maneuver into and drive an open-frame vehicle (eg. tractor), proceed to a building and dismount, ingress through a locked door using a key, traverse a 100 meter rubble-strewn hallway, climb a ladder, locate a leaking pipe and seal it by closing off a nearby valve, and then replace a faulty pump to resume normal operations — all semi-autonomously with just "supervisory teleoperation." That's a tough challenge, but it should be fun! It looks like there will be six hardware teams to develop new robots, and twelve software teams using a common platform (PETMAN anyone?!). The most crazy part about all of this: The United States is getting back into the humanoid robot game... in a big way!"

Javascript is broken in a number of ways. Just watch this video: WAT.

The fact that commutativity does not hold for "[] + {}" is just wrong! I understand the need for "pretty graphics" and "instant gratification", but a different language would have been appreciated. Heck... a background in python would at least set them up for a lifetime of scientific computing.
