The second generation had 18 motors that allowed all four limbs to move independently and the head to rotate 180 degrees. It also had visual, auditory and tactile sensors, understood commands from its owner, "liked" to have its head petted and paw shaken, and showed its mood with its eyes--they shone green when it was happy and red when it was angry. The fifth generation was even more amazing.
「愛寶二代」的全身有 18 個馬達，四肢可以靈活轉動，頭也可以 180 度搖擺，還有視覺、聽覺、觸覺等能力，聽得懂主人的指令，喜歡主人摸它的頭、握它的腳，高興時，眼睛會發出綠光，生氣時則是紅光。
