Motor Types

[WillC]

Hi

i am currently designing a micro robot that has to be around 1 cubic centimetre, (10mm by 10mm by 10mm) but i have the problem that the robot will be carrying an object that weighs 50grams, given that the robot will estimately be 10grams (including motors), this means that the motor(s) required need to be high torque. i have been looking at the smoovy 0308b and 0515B the 0515 being the most likely as it has h torque, bu both these motors are just a bit physically to big for my requirments and i was wondering if anyone knew of any smaller motors that i could look into? the max torque is going to be around 10mNm but the size of the motors need to be like 8mm length does anyone know of any?

thanks for your time reading the forum

Here are some pretty standard dimensions:
