Frequently asked questions
VC0403 or VC0410?
Both are 4-axis. VC0403 (3 kg, 850 mm) is lighter and more affordable for small parts; VC0410 (10 kg, 950 mm) handles heavier boxes and palletizing. For tilted or welding tasks, choose VC0503 or VC0606. Tell us your task and we will advise.
Can it work with cameras and grippers?
Yes. Robot3T integrates vacuum and electric grippers, 2D/3D vision and conveyors, and can deliver a complete cell.
Can I program it myself?
Yes. The graphical teach pendant is designed for operators. For developers, an SDK is available for integration with your own software.
