Extreme Explorers’ Hall of Fame: FIDO
- Favored extreme exploration environs: Interplanetary (Mars)
- Summary: The purpose of the FIDO (Field Integrated Design and Operations) rover is to simulate, using Mars analog settings, the complex surface operations that will be necessary to find, characterize, obtain, cache, and return samples to the ascent vehicles on the landers.

110 cm long
53 cm high
61.8 kilograms or 136 pounds
- Mast: The mast extends 1.94 m above the ground. It includes a Pancam, Navcam and Infrared Point Spectrometer (IPS).
- Body: The Mini-Corer, caching tubes, and stereo Bellycams are mounted to the body of the rover. The rover has autonomous hazard avoidance systems on-board, consisting of body-mounted stereo cameras (Hazcams) that examine terrain immediately in front of or to the rear of the rover. Obstacles judged too high to go over (approximately 30 cm for FIDO) are avoided by going around them.
- Instrument Arm: The instrument arm includes a Mössbauer Spectrometer and Color Microscopic Imager. A brush will be added before the next field tests, and a Raman Spectrometer was integrated for June 2001.
- Top speed: Approximately 6 meter per minute on flat terrain.
- Power sources:
- Total power:
Wheels – aluminum with steel spikes and cleats
Rocker/bogie structure – aluminum tubes
Chassis – aluminum honeycomb with aluminum face sheets; aluminum side panels
Strongback – carbon-fiber composite honeycomb with carbon-fiber composite egg-crate with carbon-fiber composite face sheets
Mast and instrument arm tubes – carbon-fiber composite Remainder of FIDO structure – aluminum
