Freds Left Hand Part 15

Fred's Left Hand Part 15

All the files for this project can be found on the http://inmoov.fr/ website The Inmoov robot was designed by Gael Langevin and released as Open Source under the creative Commons Attribution-NonCommercial 3.0 The hand being built in this project is the Version 2 hand or the i2-Hand. Over the last 14 parts we built the forearm, the hand, instlled the servo, tendos, springs, sensors, servo driver, PSU for the servos and installed it all onto the robot. In Part 15, lets start setting up the MRL service and the Inmoov2 system.

So a little bit of a disclaimer. During the initial testing, I could not work out why the system wasn't working. The answer, I forgot to connect the power for the sensors and driver board. This is the first time I have used the TCA9548A I2C Multiplexer. Let hope it works :-)

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 In Part 6, I installed and wired the PCA9685. In Part 7, I add the Elbow gear and connect all the tendos to the servos. In Part 8, I test out the MPU6050 and the finger sensors. In Part 9, I mount the bicep servo and 20A SMPS to the back of the Bicep. In Part 10, I connect the forearm to the bicep and setup the pot and bicep servo, testing the joint with a servo tester. In Part 11, I attached the assembled arm to the shoulder on Fred. In Part 12, I wire up a board with terminals to connect the various feeds to the TCA9548A I2C Multiplexer. In Part 13, I install the module I wired up last week into Fred's Back In Part 14, I connected the 5V control power to the new arm.
