Is there a way to connect an external gripper driven by a servo to the 32U4 Zumo Robot?
Thank you for your help

Hi, Willy.
I do not have any specific advice for how to physically connect a gripper to the Zumo32U4 chassis, but you might find the instructions for modifying the Arduino servo library to use Timer3 instead of Timer1 helpful. You can find those instructions in the “Controlling a servo with an Arduino Leonardo or A-Star 32U4 Prime” section of the Pololu Zumo Shield for Arduino User’s Guide. The Zumo32U4 uses Timer3 for its proximity sensor LEDs, so you would not be able to use both the proximity sensors and the gripper at the same time if you make the modifications to the servo library.

Thank you for your advice
Would be a good idea to change the PC Board to Zumo Shield for Arduino with a Leonardo Board? I mean, The same chasis supports the Zumo Shield for Arduino?

Both the Zumo Robot for Arduino and Zumo 32U4 Robot use the same Zumo chassis. However, the Arduino Leonardo uses an ATmega 32U4 (the same microcontroller as the Zumo 32U4), so you would probably still need to make the same modifications to the Arduino servo library to use it.
