Using spare parts and mission plans developed for NASA's Curiosity Mars rover, the space agency says it can build and launch the rover in 2020 and stay within current budget guidelines.
The main arm includes five electrical motors and five joints (known as the shoulder azimuth joint, shoulder elevation joint, elbow joint, wrist joint and turret joint). Measuring 7 feet (2.1 meters) long, the arm will allow the rover to work as a human geologist would: by holding and using science tools with its turret, which is essentially its "hand."
