Hi. The tendon of right thumb proximal has been replaced. Also replace the sheaths to try to prevent the tendon from rupturing again. @sgiraz proceeded to re-solder the proximal motor encoder cable of the thumb to the mais board. Replaced connector from the same engine as it was burnt. The robot was restored and tested with the help of @AntonioConsilvio.

Thanks @GiacomoVassallo13 @AntonioConsilvio @sgiraz !

The tendon broke again. I attach a video (with the audio) of how it happened in case it may be useful.

Hi. Today i replace the broken right thumb proximal. The motor was tested electrically with a jogger and the correct reading of the optical disc was verified. I also restored the right ring distal tendon. The robot has been tested and it works properly.
