Jaehoon Kim and other authors have published a scalable analog sensor readout architecture based on serial-in parallel-out (SIPO) shift registers, in which only three signal lines are needed between sensor modules for expansion. The authors state that they integrated 16 joint sensor modules and 1 four-channel tactile sensor module on a tendon-driven dexterous hand, achieving full scanning of 20 channels at 1 kHz, with stable operation up to 1.5 kHz; the maximum slope absolute percentage error of the joint sensors is 0.446%. On the tactile side, the authors used an LSTM model to perform force estimation and contact position classification at 1 kHz. The above performance results were all validated on this tendon-driven dexterous hand experimental platform.

- High-Speed, Scalable Sensor Readout Architecture for Dexterous Hands Based on Shift Registers
The paper proposes a scalable analog sensor readout architecture based on serial-in parallel-out (SIPO) shift registers, in which sensor modules can be expanded using only three signal lines. The authors integrated 16 joint sensor modules and one four-channel tactile sensor module on a tendon-driven dexterous hand, achieving full scanning of 20 channels at 1 kHz and stable operation up to 1.5 kHz; the maximum slope absolute percentage error of the joint sensors was 0.446%, and on the tactile side an LSTM model performed force estimation and contact-location classification at 1 kHz.
