Collaborative robots are a new class of robots called cobots or collaborative robots. They have the ability to work directly alongside humans, without safety cages after a prior risk assessment. Such robots can bridge the gap between fully manual assembly and fully automated production lines. Interest is particularly evident in the small and medium-sized business sector, which until now has considered robot automation too costly and complex to even consider. Cobots are lightweight, flexible and can be easily moved and reprogrammed to solve new tasks. They address the challenges of short-run production faced by modern companies adapting to increasingly sophisticated technologies for manufacturing in smaller batches.
