Hi all, I haven't used tsr in about 5 years so forgive me if this is in the wrong sub, (physics might of been a another option)
Anyway, I'm currently working on a project at work where we are building a robot to pull around a drinks trolley that we have purchased (currently pushed around by a person).
And I need your help to figure out how much mass the robot we have bought can pull.
I work for a finance company so my team has not got the best mechanics knowledge. I did do m1-m3 at a-level and maths at degree level but I have forgotten most of it, so I need your help!
I have got a vague idea on how to figure it out. I have attached below my initial workings and the sort of setup we have. But I don't really know where to go from there. (I have forgotten how to balance forces). I also don't how how to use the torque to get a force.
This is the robot we have bought.
So some important figures,
the mass is 2.7 kg
11 kg-cm (160 oz-in) per motor
Probably some more good info in the link above.

Since you have the thing, you would be far better off dropping a string over the edge of a table and progressively loading it until the thing won't pull.
It is likely that your main problems will be to do with terrain and how well the wheel/tyres cope with the office floor.
