The model rover's design had input from the real-life Curiosity rover engineer, Stephen Pakbaz, so it’s about as accurate as you can get, within the confines of the LEGO system.
The LEGO version of the highly advanced mobile Mars laboratory features lots of neat detail, such as the six-wheel rocker-bogie suspension, articulated robotic arm, and multiple cameras.
It reminds us that the LEGO Technic system is really quite excellent, with uses that go beyond super-real scale models, as supplied by the kit manufacturers. Provided you don’t get frustrated by LEGO’s limitations, the world is your oyster, with ideas set only by your imagination.
