Google’s parent company Alphabet has put Boston Dynamics, part of its robotics division, up for sale for lack of revenue potential.

The possible buyers include Amazon and carmaker Toyota’s research and development company the Toyota Research Institute (TRI).

Boston Dynamics, bought by Alphabet in 2013, is best known for building robots that look as if they belong in a science-fiction movie and are often co-developed or funded by the US military.

The company has designed high-profile robots, such as BigDog, RiSE, and Atlas.

Boston Dynamic's other products include Cheetah, which it claims to be world's fastest legged robot as well as a robot that climbs vertical terrains such as walls, trees and fences.

Amazon has installed thousands of robots across its warehouses to cut operating costs and get packages out the door more quickly.

TRI said in January it had hired a team of scientists and engineers to help drive research into artificial intelligence and robots.

A recent report published on Research and Markets expects the global robotics market to grow at a rate of 29.11% over the period 2015-2019.

It says industries worldwide are demanding better precision and efficiency in order to meet the growing end-user demand.

This has led to high demand for machines that are capable of increasing industrial efficiency by handling multiple tasks while remaining uncompromising on overall accuracy.
