Prototype? Come on, did you even check their website? Octopus Robots company runs over 30yrs. The company is listed on the French stock exchange.

Here you will find some videos of robots: http://octopusrobots.com/en/home/#therange

Octopus Robots has a lot of robots on offer and as far as I know their prices are in the $4k-60k range
