Professional logo design. Design a sleek and modern logo for a chatbot application. The logo should feature a minimalistic robot face or icon integrated into a smooth, rounded chat bubble. Use a clean and balanced color palette of pastel blue and white, with subtle gradients for a professional yet approachable feel. The robot should have simple features like a smiling face or expressive eyes to convey friendliness and intelligence. Pair the icon with the chatbot’s name in a clean, sans-serif font, positioned either beside or below the icon. Focus on simplicity, symmetry, and elegance, ensuring the design looks polished and versatile across platforms.
