FingerTech Viper kit with titanium top armor and wedge. The center third of the wedge is hinged with a servo underneath acting as a lifter. While it was supposed to be self-righting, the specs on the servo overstated its range of rotation, leaving Tipsy unable to lift its arm far enough to self-right. The unique linkage used internally to connect the lifting arm to the servo also results in significant internal forces that bend the entire structure of the bot!
