So you want to control a tank with your iPhone or Android smartphone?

When it comes to robotic pets I still have my heart set on one day owning a Sony AIBO as I always wanted one when they arrived on the geek scene, but could never justify the cost. The Desk Pet TankBot is no AIBO; for a start it's a tank and not a dog, it's a lot smaller and far less intelligent no matter what the packaging blurb tells you. Oh, and it's nowhere near as cute either. But then again, a second hand AIBO (should you be able to find one for sale in good working condition) is going to set you back more than £1000 ($1500)whereas the TankBot is only £25 ($40). So what do you get for your money?
