At Rebots, we are official distributors of Dobot Robots, with most of the CR series in stock in our facilities in the Basque Country.

First, a description of the most important aspects of the DOBOT CR series as a whole:

  • Easy to use: Graphical programming (Blockly like scratch) is intuitive and easy to understand, making it highly accessible and ready to use. The interactive button panel on the wrist allows for hand-guided learning and free drive joint movement effortlessly with just one hand. It can be controlled in real-time on your mobile phone, tablet or computer via wireless for a seamless operation.

  • Cost-efficient: The system requires little investment, and virtually no need for additional protective measures, all while ensuring utmost safety and flexibility in confined areas. Thanks to its impressive service life of over 32,000 hours and low power consumption of only 100 watts, it stands as a durable and highly efficient solution that yields long-term benefits while significantly reducing operational costs.

  • Safety: The system offers real-time dynamic monitoring with a response time of 0.01 seconds, providing quick and precise feedback. It also features a pre-touch perception capability (Safe-skin )that detects objects within a ~15cm range, enabling advanced perception for proactive preventive measures, utilizing electromagnetism. By combining spatial perception and online planning, it intelligently selects the optimal trajectory to navigate around obstacles, adapting efficiently to unpredictable strains and challenges.

    • The unique feature: Dobot's Safe Skin.
