Bruce and Alfred used the computer to watch Dick working out in the gym.
A secret rendezvous took place in the Batcave involving
Batman, Robin, Nightwing, Oracle, Aquaman, Miss Martian, and Wonder Woman. They exchanged intel and discussed the details of their coordinated efforts to disrupt the meta-human trafficking activities of Simon Stagg.
The Batcave consists of bare rock and metal support frames with a number of floodlights and spotlights to provide illumination. A metal platform houses a powerful computer
which uses the same system as  Justice League computers. The computer can be used to view and analyse footage from cameras inside Wayne Manor  and mounted in Batman's suit.  The platform also holds a lab bench with microscope, and a set of steps leading down to a lower level where the  Batmobile is stored.  The cave also has Zeta-Tubes.
The Batcave is one of the most iconic locations in DC Comics and pop culture at large. It is here that Batman stores all of his eccentric vehicles and memorabilia from his most famous enemies.
