Technical Specifications

Operational Recommendations

• Plan work sessions considering the autonomy time: approximately 2 hours for the upper part and approximately 6 hours for the chassis.
• For manipulation tasks, check the arm position, as the maximum load of up to 3 kg heavily depends on the manipulator's reach and position.
• Consider the capabilities of the integrated RGB cameras in the Dex3-1 hands, as they provide detailed visual control directly in the gripping area.
• For navigation tests, leave enough space for the base to turn on the spot at 360°.
• Before data collection, set up a clear task sequence: scenario creation, assignment, collection, annotation, verification, storage, and export.
• During machine learning tasks, check the compatibility of models with open-source datasets, as well as with PI or GROOT frameworks.
• When working with fragile or non-standard objects, start with low gripping force values and gradually increase them, focusing on visual control from the RGB cameras in the hands.
• Regularly check the calibration of the Dex3-1 hands before long work sessions.
