Freds Left Hand Part 6

Fred's Left Hand Part 5

When you think of a hand, you tend to look at from the tips of the fingers back to the wrist.
But in the human hand, most of the muscles that drive the fingers are located in the forearm.
This is the same with the Inmoov robot.
So our journey we will start with the forearm.
This is convenient as I already have Fred's arm built down to his elbow on the left side.

In Part 1, I decided to use PTEG.
For the forearm, most of it is a standard build except for the modified wrist.
In Part 2, I used a few nutserts and installed the servos.
In Part 3, I started on the version 2 hand its self.
In part 4, I installed the 5 Hall sensors and the springs.

In Part 5, I installed the electronics and the PTFE tube
The PTFE tube are 1.5mm ID and 2.5mm OD with the following lengths:
Thumb 335mm
Index 300mm
Middle 300mm
Ring 300mm
Pinky 360mm

Part 6 see the PCA9685 installed and wired
