The European Space Agency announced this week that its three-armed robot -- affectionately dubbed Eurobot -- recently underwent a Weightless Environment Test (or WET), and passed with flying colors. The bot's three arms are similar in size and strength to their human counterparts, although Eurobot's limbs are jointed in seven places, thus allowing them to move and pivot in ways human arms cannot. The "neutral buoyancy" test was meant to examine whether or not the robot would be able to complete simple tasks such as putting away tools and equipment, or holding objects for workers in a weightless scenario. The hope is that Eurobot will make its way to the ISS, where it will enable astronauts to accomplish repairs and maintenance with greater speed and safety. Needless to say, HAL was unimpressed.
