This week I finish the redesign of the servo motors holder. With the first picture being the original design. The problem with this was that the servo motors were too close to each other and causing tension to servo.
The new design is being the overall the same but the distance between the sevros is increased by 1.5 mm as holder needs to fit in the same place as the original design so it can't be too different to it.
This did took a good bit of time during the week as the print did take around 3 hours to print. And I had to reprint it two time, cause the first version I made had some problem in it. Such as I made the floor of the holder was too tall and some of the distances were a bit off. So I made adjustment to it to make it work perfect and it worked. Once the print was done I reassemble the arm back together so we can test it out again.
Unfortunately even with loosing the tension on the fingers and the new holder, the servo motor were still not able to pull the finger. So I find a new set of servo motors that will be much stronger than what we currently have. I found a set of servo that should work. They have a 11 kg-cm Torque compare to the 0.2683 kg-cm which will cause it to several times stronger than the last one. .
My plan for next week is to focus completely on the base and try to finish it also to updated the report on the hardware side of it.
