top 5 coolest sci-fi robots, my picks based on icon status and pure vibe:

1. r2-d2 (star wars) - the ultimate sidekick: loyal, gadget-packed, and never shuts up.

2. t-800 terminator - arnold's unstoppable killing machine turned protector. sheer badassery.

3. wall-e - pixar's lonely trash-bot with a heart of gold. dances with vacuums.

4. hal 9000 (2001: a space odyssey) - creepy ai overlord who hums while plotting. chills.

5. bender (futurama) - foul-mouthed, booze-loving bender. robot goals.
