I finally built one. Now how do you upgrade it. By the way you have to have level 8 in robotics to build it and by the time you craft enough parts to actually build the thing you will be level 10. ...
No. It's just slow. What you need to do is work on the Servo's skills. Improving skill increases the % of improvement. Once you reach 100% then you need to do the improvement which will require parts, computer chips and mechanisms, and the required level of robotics skill.
