How to read the figures

1,100mmB43.3inB: A dashed letter marks a secondary source – a datasheet, manual or developer documentation from the manufacturer, or a press report used only where the manufacturer gives no figure.
Payload, walking: A stroke before a field name means the figure carries a caveat that affects how it compares with other robots. The caveat is printed with the figure.
74.5lb: Imperial figures are our own conversion unless the manufacturer states an imperial figure itself. The source letter always belongs to the metric figure — a conversion has no source of its own.
