A robotic toy has a pedestal, a stand assembly, a transmission device, a shoulder, an arm assembly and a body casing assembly. The stand assembly is mounted on the pedestal and has an upper bracket. The transmission device is mounted pivotally on the upper bracket of the stand assembly and has a hollow body, a motor and a gear assembly. The shoulder is mounted movably on the hollow body and oscillates in response to the motor. The arm assembly is attached to the shoulder and has a forearm pivoting up and down in response to the transmission device. The operating motor causes the transmission device to rock, the shoulder to oscillate and the forearm to pivot up and down. Thereby the robotic toy with a decorative musical instrument looks like a lively person or creature playing a musical instrument.
