Why get a system that can only do surveillance work when you can get one that can do that and blog as well? Bandai's new robot presented during Robot Japan 2008 conference called NetTansorWeb can do both mentioned functionalities. The NetTansorWeb robot that's meant for home use can be controlled via WiFi and is properly built with cameras for surveillance. Since it can move autonomously, it's also equipped with sensors to avoid obstacles. The robot can send you reports of its surveillance through the computer or through your phone when you're away.

Aside from its security features, the NetTansorWeb takes a leaf (pun intended) out of Midori-san's book and can even blog. If you got one explosively successful blog, for example, it can monitor the comments section and respond to requests for image re-uploads. Unfortunately, its measly two and a half hours of battery life is a deal-breaker. However, it's still a good home surveillance option that costs only $500. The Bandai NetTansorWeb will be available in the company's home country of Japan by December.
