Dimensions & Degree of Freedom Distribution
160mm From Palm Base to Middle Fingertip
The Revo 2 Basic measures 160mm from the base of the palm to the tip of the middle finger, weighing 383g, with a maximum opening and closing distance of 100mm from thumb to index finger.
6 Active Joints, 11 Total Degrees of Freedom
The thumb has two active degrees of freedom for abduction and adduction, plus one passive degree of freedom for flexion and extension. Each of the remaining four fingers has one active degree of freedom for flexion and extension, plus one passive degree of freedom for flexion and extension.
RS485 or CAN FD, Located Beneath the Wrist
The Revo 2 Basic can communicate and control via the 485 or CAN FD communication interface. The interface is located under the wrist, with connector model BM05B-PASS-TFT(LF)(SN).
