My new ant comprises of a lifting arm that is simillar to biohazard but has a slider bar rather than a 4th arm at the back (very simillar to alpha raptor) does anyone know an online calculator for bar lengths, torque etc.

How about a linear servo?

Due to weight and the simplicity I want to keep my ants at, I have planned to use a direct rotory motion using a servo (like storm 2) the only headache is the lengths of all the bars and the slot.

Not sure if it's what you need, but I did write a javascript calculator to convert torque between Nm, kg-cm, oz-in etc and also calculate the force provided by a given torque at a given distance.

Here it is:
