Experiment 1 and 2 Data Collection

1. Experiment 1 – Mobile Robot

Variable	Conditions
Robot Size	Mobile base only (500 mm Mobile base and 1-level cart (1000 mm) Mobile base and 2-level cart (1500 mm)
Robot Speed	1.0 m/s 1.5 m/s 2.0 m/s
Robot Movement	Straight lines (90 degree turns) Curved lines

Description: Start at the starting point, walk to the load point among the racks, pick a box from the rack, place it on the empty mobile robot, and then return to the starting point. Figure 1A and 1B show a top view of the test configurations. They will complete 1 loading task and will encounter robots with the selected height, moving speed, and movement path type while moving to the loading sections. One movement path condition will be tested for each configuration. Figure 1A will be used for the straight movement path condition and Figure 1B will be used for the curved movement path condition.

2. Experiment 2 – Collaborative Robot

Variable	Conditions
Robot Size	UR3 (arm reach 500 mm) UR5 (arm reach 850 mm) UR10 (arm reach 1300 mm)
Robot Speed	60 deg/s 120 deg/s 180 deg/s
Robot Movement	5 (base, shoulder, elbow, and 2 wrists) 6 (base, shoulder, elbow, and 3 wrists) 7 axes (base, shoulder, elbow, and 4 wrists).

Description: A participant and a collaborative robot with different size, moving speed, and number of axes will be in opposite sides of a working station. There will be a total of 10 objects in two different shapes (square or round, five each) on the table, and a participant and robot will pick up the target objects and place on a tray in front of them. Objects will be dispersed at pre-selected locations within the working area to make arms of a participant and the virtual robot cross paths. The schematic in Figure 2 shows a top view of the virtual reality simulator layout.
