if the blue bot is keeping the red bot from pulling itself up, it MUST be supporting some of its weight on the red bot, it could not possible be preventing the red bot from ascending if most of its weight were not supported by it

and the red is clearly supported by its wheels

so neither are entirely supported by the bar

neither are hanging

BTW - this would be easy to determine - bluebots cables or hook arm would be loose on the bar, or slack, it its applying force to the redbot
