Meet our Cobot

A "cobot," or collaborative robot, is a type of robot designed to work alongside humans in a shared workspace. Rainbow Robotics's cobots are compact, flexible, and easily programmable, equipped with advanced sensors and software for safe and efficient human-robot collaboration.

Rainbow Robotics's cobots are widely used across various industries for tasks such as assembly, packaging, quality inspection, and logistics, enhancing productivity and precision.

With RBW’s easy to use interface, RB cobot becomes a fast learning welding cobot. You can start producing quality welds in just minutes. Repeatable, efficient, fast. Every time, all the time.
