I'm new to webots and want to design simulation using PUMA560. In there I need to change the gripper shapes and size. But when I replace the existing gripper with a new solid box shape, suddenly everything went disappear. How can I edit the proto file?
I tried updating the gripper slot by using the Pioneer3 gripper. but still, the previous gripper exist. How can I remove it and combine the existing controller to the new gripper?
