This is an interesting idea. Robots don't need to have human rights. They can have 'robot rights'. In Bolivia, for example, there are rights of nature (applies to living and non-living things) [1]. There is also a strong advocacy for animal rights. The concept of 'right' doesn't only apply to humans.

Corporations have rights of 'artificial persons', which are not identical to rights of 'natural persons'. There are differences, like:

  - Corporations can be owned (enslaved), bought and sold. Humans can only be rented (a job, service).

  - Corporations have tax advantages (deductions, deferring taxes on foreign income etc.) that regular humans don't have.

  - Corporations don't go to prison; they just pay fines when they break the law.

  - Corporations can easily become citizens of most other countries through subsidiaries, while humans cannot easily do that.
