This is my 16th robot project EWA. Built from a Walle Ucommand toy. It has a 3d printed head from Xlrobots. I added a cooling fan to the front for a more industrial look. He has led mouth that uses a sound mic.Used hd servos for the head and neck. Micro servos for the arms and continuos hd servos for the tracks.Uses EZB V3 as controller .Installed 5000 mAh li-ion battery pack. Has carry handle attached to his back. Left the original sound board for sound effects. The concept is that if Walle and Eve had an offspring this what he would look like..Makes great little companion in my workshop.
