The problem with that theory is a strategic partner could buy the company now at total valuation of less than 100 million. Most of the warrants would be worthless as well as stock options. That would be cheaper than buying more stock over the next two years and still not being sure of success and owning only half of the company.
If there is a secret partner funding the company, maybe they don't want to spend any more money because they see problems with the design and want to see if the fixes funded from their 27 million actually produce a viable product before investing more.
Either way to cause of timeline delay is a robot at this time that does not have the tech to make it to market as per management.
