SKKU (SungKyunKwan University)
This group has developed numerous robot hands over the years.
They had on display 3 research prototypes: a 3-fingered robot gripper and two
anthropomorphic hands that each have 3 fingers and an opposable thumb.
They have published various papers, such as:
Choi et al., “Development of Anthropomorphic Robot Hand with Tactile Sensor: SKKU Hand II”, IROS 2006 PDF
Choi et al., “The SKKU hand: Work in progress”, URAI 2012 PDF
This robot hand and arm uses artificial muscles for actuation.
