Hey
I have written the following code for one assignment at uni, but it is not working as i would like. could you, please, help me?
I would like to give this arm as the maximum possible moviments as a human arm, like it shouldn't move 360, etc
can you help or give any tip, please?!?!
many thanks
It has some words in portuguese coz this is my mother language
ombro means shoulder
antibraco means arm ( between shouder and elbow )
braco means arm ( between elbow and wrist )
dedo means finger
thanks again
