It's Johnny Five!
Seriously, this rover and its opposite number are intricate little robots. I sure hope nothing goes wrong.
On-board memory includes 128 MB of DRAM with error detection and correction and 3 MB of EEPROM. That´s roughly the equivalent memory of a standard home computer. This onboard memory is roughly 1000 times more than the Sojourner rover from the Pathfinder mission had.
Just think; that mission was only 6 years ago.
