Pepper Robots are starting to appear on the second hand market, ebay etc. Some are even "not working" models for around $2500 US. Shipping from Japan sometimes appears to be more expensive than the robot itself.
I was considering buying a broken one and my logic was I get the casing servo's motors screen in a professional robot shell, but not really sure the level of complexity in hacking these and integrating servos cameras sensors with EZ-B and if it is really worth the money or better off building an inmoov or similar. I printed an inmoov hand and forearm but time 3D printing cleaning up, servos etc... and I can't use in a business setting as the license is restricted.
There is a tear down with photos here but not really a lot of details. https://tech.nikkeibp.co.jp/dm/english/NEWS_EN/20150625/424978/
