the research should be like this.
title( KUKA KR 60 HA end-effector)
so start talking about
1- the end-effector in general (types,price,... etc)
2- the design of the end-effector (material used and the effector dimensions..etc)
3- the internal design of the end-effector ( the placing of the holes and its diameters, the shape of the effector...etc)
4- the connections of each piece of the effector ( how to connect each piece to the other pieces to the effector using which kind of bolts/screws/materials and which holes used)
5- the connection of the effector to the KUKA robot
Take in mind all should be about the KUKA KR 60 HA model, all measurements and calculations should be in the paper. exact sizes,dimension,types, and materials should be included. providing figures.
reference should be accessed online and it should be 4 pages long
