GOSY's PROPRIETARY SOFTWARE IS UNIQUE
GeckoSystems has developed a suite of proprietary software which they have proven to be portable. They successfully demonstrated this software on their CareBot and on wheelchairs. This obstacle avoidance software has been termed "SafePath" for use on wheelchairs.
Demonstrations of this unique software used on the CareBot can be seen in the world's first in-home robot trials. See the following link for verification:

Demonstration of this unique software for wheelchairs (termed "SafePath") can be seen at this link:

IMO this is a great company to invest in because of their proprietary software and capable management.
