Robotic animal puzzle

A robotic animal device comprising:

• a head portion, a torso portion, multiple leg portions, and a tail portion;
• the head portion comprising a neck group operably coupled with the torso portion through a tilt group and a pan group;
• the tilt group comprising a middle piece, a mouth piece, an eye piece, a chin piece, at least one ultrasound sensor, an ear piece, and a tilt servo motor operable to tilt the head portion;
• the pan group comprising a pair of opposing neck pieces, each of the neck pieces interlocked with a base piece, the base piece attached to a small servo arm, a pair of small lock portions, and a long servo arm;
• and a panning servo motor connected between the base piece and a shoulder portion connected to the torso portion;
• and
• the torso portion comprising a top torso piece and a bottom torso piece, a battery holder configured to receive one or more batteries, the battery holder movably attached to the bottom torso piece for adjustment of a battery position along the bottom torso piece, at least one means for tuning a center of mass by adjustment of the position of the battery holder along the bottom torso piece;
• and the multiple leg portions movably attached to the bottom torso piece to support and to control movement of the robotic animal device;
• wherein the tilt group comprises the mouth piece and the eye piece slidable into the middle piece;
• the chin piece interlocking with the middle piece in a locked position;
• and an upper surface of the chin piece configured to urge a lower edge of the chin piece to lock the chin piece in the middle piece.
