We haven't heard a whole lot about Singapore's DARPA-esque TechX robot challenge since it first kicked off early last year, but with the final round getting underway on Sunday, Popular Mechanics has now thankfully offered up a preview of what's in store. Among those set to compete is the so-called Uni-Seeker bot (pictured above) from Nanyang Technological University, which is a heavily modded incarnation of iRobot's ATRV Junior robot, and one of only six bots that managed to make it through all the qualifying rounds. Others include the considerably more intimidating AZROBOWAR Sharp Shooter, built completely from scratch, and a pair of robots built on iRobot's popular PackBot platform. From the looks of it, they'll each have their work cut out for them in the big event, with them required to start outside and navigate their way inside a building, then climb a flight of stairs, travel up an elevator, touch a few targets, and then exit the building again -- without any human intervention, and in less than an hour. That $700,000 prize should provide plenty of motivation, though.

We already caught sight of Sony's ZS-S4iP iPod dock / boombox when it turned up in Australia, but it looks like there's a few more Made for iPod devices where that one came from, with Sony now also debuting three more docks of various sorts. That includes the clock radio-style ICF-CD3iPSIL model pictured above, the HD Radio-packing XDR-S10HDiP (after the break), and the plain-old SRS-GU10IP (also after the break), which provides one big speaker and nothing else. From the looks of it, the XDR-S10HDiP and SRS-GU10UP are both available right now direct from Sony and will set you back $180 and $150, respectively, while the ICF-CD3iPSIL will only be available at the end of the month, though you can get a pre-order in now for $100.
