The robot is very easy to use with its intuitive UI that makes it simple even if you are not familiarized by robotics as I am myself! It can be used both indoor or outdoor without any problems since there isn't much difference between them when using this product so far. There aren’t many downsides about geckos but maybe some people may find difficult understanding how they work because of their complexity compared to other products available out today such as KUKA which has more user friendly features than what we have here at GEKO ROBOTS. We were able solve our needs while being cost effective solving issues related to quality control during production line process.
