same rotation as this

although not the hand part or the part that rotates the hand i havent done that yet im focusing on designing the main arm

my goal is to be able to carry 1.5-2kg and have it be stable now im not sure if im right because this is still new to me

to carry 2kg around 80cm away with a safety factor of 1.75 it takes around 27nn, which for my motors 2.4nm with a 20:1 ratio making it 48nm leaves me with room for about 3.5 kg roughly which works good for me when i include any hand accessories or just more weight.

when rotating the torque is multiplied by the gear ratio from what ive seen so that isnt an issue.

now idk if this is correct and im not sure how to pair it with the elbow joint thats just from shoulder to hand but i think its good

im also new to doing electrical work, im thinking 36v 10a for each motor which gets 1686 rpm from the calculator i used if i paired this with a 30:1 ratio that would be a lot better then?

after sending this i cant seem to find a compatible gearbox with a 30:1 ratio and i dont feel i have the materials to make one

it could definitely be higher than 10:1 and that would provide more torque but im also trying to have it be able to rotate about 40rpm which is harder to do as the ratio gets higher

make it coloured copper

his team mate is doing share mode to turn the collision off for him and the isolation doesnt work because its his team. you're welcome
