Experimental configurations (particle diameter D, extension angle α₊, maneuver velocity v) and the corresponding critical resting times (printed in bold) determined by stepper-motor and by lever-arm experiments (“X” indicates that a successful SM could not be performed for the tested range of resting times).

Particle diameter D	Extension angle α+	Maneuver velocity v
		90°/s	135°/s	180°/s
Stepper-motor experiments
180 μm	20°	29 s	26 s	24 s
250 μm	0°	X	X	X
250 μm	10°	X	33 s	26 s
250 μm	20°	16 s	13 s	12 s
250 μm	30°	9 s	8 s	8 s
Lever-arm experiments
250 μm	20°	16 s (12 s)	11 s (8 s)	10 s (8 s)

For the lever-arm experiments, the lower values in parentheses indicate the critical resting times for which SMs were only intermittently successful.
