Only if you have a very narrow idea of what a robot looks like. The Toa have lots of exposed mechanical details like pistons and such. They have a "clockwork" look like you might see in a steampunk universe. But a lot of real-life robots and machines, such as ASIMO and Robonaut, have much smoother, cleaner-looking designs. Even a car or plane generally has a smooth, streamlined body made of metal plates, with the mechanical innards hidden underneath. I was thinking the exact same thing! I thought that the Bionicle Universe inhabitants seemed much more organic than the HF ones, and you make a good comparison here. I agree with you about Bionicle being to customize mainly because you able to attach Technic pins and axels and nearly every weapon had an area to put/attach Technic pins and/or axels
