engineers at the dfki robotics centre describe the eossc2 -lrb- animated -rrb- as an ` ultra flexible micro-car for mega cities ' and plan on enabling it to drive itself .
the eossc2 flex the second joint of each leg to move sideways , like a crab , so it can park itself .
crabs have a wide flat body to make it easier squeeze into narrow spaces and the eossc2 works in a similar way .
