Time difference between two consequent timestamps 'step_size'
The data was collected as follows: Two humans were asked to co-manipulate a load of 10 Kg (together). One human was acting like a leader, and the other one was asked to follow. The only allowed communication between the follower and the leader is through the haptic clues (measured using 6-axis force/torque signal). The follower had EMG muscle activity sensors on the right hand (arm/forearm). Finally, the object position was tracked using an eight-camera VICON system. All sensory data were synchronised using ApproximateTime synchroniser; hence, they have the same timestamp. These datasets were collected through a GitHub tool available at: https://github.com/Intelligent-Automation-Centre/bluebox. The tool is explained in more detail in Al-Yacoub et al. (2020).
