VENUS 6 is released and is available for the VANTAGE platform. There is no future development planned for INSTINCT V.
The track gripper has had considerable improvements in its reliability and has a new calibration tool. I recommend working with the local sales team to configure the system that best accommodates your needs though. It may be that an iPG is sufficient as you can integrate to the rear of the system. The track gripper would provide more integration options though.
If you need any assistance getting in touch with your local Hamilton sales team, please let me know!
