The SILO6 is the 2nd robot developed by CSIC, the earlier version was SILO4 (a quadruped). A robot with 6 legs is capable of moving faster than one with 4 legs, so this version is a hexapod. An insect-type leg configuration requires more torque, and thus more power, so the researchers experimented with a pseudo-mammalian leg configuration (which requires much less torque). However, in the end the robot uses an alternating tripod gait, where 3 feet are always in contact with the ground.
It has a sensor head for detecting land mines as well as objects that may be in the way of the robot. When the sensor detects a mine or suspicious area, it sends the exact location to a computer database using GPS that is accurate to within 2cm of the target. Land mine detection is a very dangerous job that is still done mostly by human beings, so a robot like this will prove invaluable in the future.
