Method
- One criterion only: weight, from lightest to heaviest. No score and no average: the order comes from one published value.
- Only general values are used: those that name neither a variant nor a particular measurement condition. For a robot, the most recently verified one. A robot without such a value is not ranked.
- Robots with an equal value share the same rank, then follow in alphabetical order. Every value links to the claim behind it, with its source and date.
- A page only exists if at least 4 robots have a comparable value.
