In between donuts and coffee and giving out tickets, police officers face some dangerous situations. The bad guys never sleep. And most of them are armed.

Enter the e-Glove. It can be worn discreetly and will help police detect hidden knives during a pat down. When it detects metal on a person’s uh person, the glove vibrates silently to warn the officer. It costs about $153 per glove right now and is bound to make police safer.

Here’s a much better way to get rich than the metal detecting sandals and it will take just as long to amass your wealth. Why wear sandals when a robot can do it for you? ThunderBird 007 is the latest version of Let’s Make Robots user Gareth’s metal detector robots.

It’s a great little bot. And when you think about it, robots should search for treasure and earn their own keep and pay for their own parts. The TB-007 features a metal detecting wand, wireless camera and a laser pointer to point out it’s finds. It could get really fun if you run into another guy controlling his own bot and have to have your robots fight for the treasure.
