"Cartoon-style 3D robot sitting on a vibrant purple chair, holding a tablet, in a colorful environment with a warm orange and yellow circular background. The robot has a friendly and approachable design, smooth and rounded features, with expressive eyes and a glowing smile. Use bright, bold colors similar to modern flat design aesthetics. Soft shadows and clean gradients to enhance the 3D effect. Minimalistic yet engaging and cheerful design."
