Ted Talk, Robots that Fly and Cooperate

No Gravatar

This 16:47 video includes many clips of quadracopters that have been posted here before, being talked about by a researcher from University of Pennsylvania researcher.  The final ‘music video’ clip, I have not seen before.

Vijay Kumar: Robots that fly … and cooperate

Thanks to Gina for pointing this Ted Talk out to me.

More online robotics courses

These are being taught by one of the Standford professors that taught the machine learning course that I posted last fall, plus a prof from U of Virginia.

CS 101: BUILDING A SEARCH ENGINE
CS 373: PROGRAMMING A ROBOTIC CAR

See Udacity or directly to CS 101 and CS 373

The robotic car course adds to the previous course, but the previous courses is not a requirement.  CS 373 assumes strong programming knowledge, but CS 101 does not need any previous programming background.

Navigating beyond the reach of GPS

Found an article about some research to allow navigation / position detection where GPS does not work.  Bigger systems already use this technology, but the research is to develop it for use on small resource and battery life constrained devices, like cell phones.  That will also apply to small, mobile, indoor robotics projects.

Ultrafine Location Fixes

Here is a link to an article from Technology Review about GPS style positioning technology that use small [it says the size of a hardback book] land based units.  Accuracy down to a few centimeters.  This version uses the same frequency [band] as wi-fi, but apparently with higher power. A single unit could cover several kilometers.  This is real technology already being used.

Ultrafine Location Fixes

One of the company co-founders is quoted as saying

Tracking goods and machines with high accuracy can enable greater use of robotics and automation.

Assuming a “location hotspot” is available, or can be setup at reasonable cost, this looks like an opportunity for robotics location awareness. Depending on thoses costs, down to the consumer level. The existing home robots that need to have hardware “electronic walls” installed could potentially use position sensing and a virtual wall instead.

How about

  • a sumobot that knows its position relative to the ‘ring’ well enough that it does not need to completely rely on optical sensing of the white edges?
  • a line follower that memorizes the path based on absolute position information? The high speed line followers could ‘plan’ acceleration, deceleration, and turns based on their position
  • a Darpa style challenge where the ‘contestant’ is given only the geo-location of the goal
