Biomimetic robotic manta ray

A biomimetic robotic manta ray, comprising

• a head cabin,
• a central cabin,
• a pair of pectoral fins,
• a caudal fin cabin, and
• a control assembly;
• wherein
• the head cabin is located at a front end of the biomimetic robotic manta ray;
• the central cabin and the caudal fin cabin are sequentially connected to a rear of the head cabin;
• the pair of pectoral fins comprise a left pectoral fin and a right pectoral fin, where the left pectoral fin and the right pectoral fin are symmetrically arranged respectively on a left side and a right side of the central cabin;
• the left pectoral fin comprises a left pectoral fin body;
• the right pectoral fin comprises a right pectoral fin body;
• the left pectoral fin includes a left first power device and a left second power device, wherein the left first power device is mounted to a left fixing member and drives the left pectoral fin body around a substantially anteroposterior axis;
• the left fixing member is mounted in the central cabin and is driven by the left second power device and the left pectoral fin body rotates around a substantially vertical axis;
• the right pectoral fin includes a right first power device and a right second power device, wherein the right first power device is mounted to a right fixing member and drives the right pectoral fin body around a substantially anteroposterior axis;
• the right fixing member is mounted in the central cabin and is driven by the right second power and the right pectoral fin body rotates around a substantially vertical axis;
• the left pectoral fin body and the right pectoral fin body are separately driven;
• and
• a control terminal of the first power device and a control terminal of the second power device both communicate with the control assembly through a first signal.
