The world of robotic pets is a large and varied one. The central place for finding out about them is here:

ElectronicPets.org – The Complete Database of Interactive and Robotic Pets.

There are a few that stand out, however:
Wowwee, makers of the robosapien have two lines that are very interesting:

The Alive baby animals are beatifully made and have a pretty wide range of functions.

Alive animals also come in ‘mini’ versions which are don’t have as many features but are still very cute. Watch out when buying though!

They also have a Perfect Puppy line (as well as many others) which are very cuddly.

Keepon is my favorite, he’s a dancing robot. The professional version costs $30,000 but there’s a smaller version available for around GBP 40,-

One of the most intelligent learning and evolving robots is PLEO rb (which stands for reborn). Unfortunately it’s insanely expensive ($469)

The fuel nozzle drip retainer is a simple yet innovative way of saving millions of litres of fuel on a global scale. Anyone who has pumped fuel before has noticed the drops that fall to the ground after you’ve removed the nozzle from the vehicle. We’ve designed a method of retaining these drops, which initiates a recycling process whereby the next customer in line receives the fuel that would have been otherwise wasted. These drops may not seem like a significant amount, however when taken into account globally, these drops amount to approximately half a billion litres of fuel that falls to the ground and is evaporated into our atmosphere every year. Our drip retainer mesh design utilizes a combination of pressure differentials and surface tension to retain fuel within the spout.
