Fig. 4: Experimental results of lateral jumping on the water surface.
From: Scale dependence in hydrodynamic regime for jumping on water
a, b Jumping trajectory, lateral velocity, and vertical velocity of SJR (a) and AJR (b). The robots are tested by varying the height of lateral drag pads with the same width of 20 mm. c Jumping trajectory of the AJR, which attached 2.6 mm drag pad. Scale bar, 10 cm. d The AJR overcomes an obstacle of up to 220 mm height. e, f Take-off angle and take-off velocity of SJR (e) and AJR (f) depending on the height of lateral drag pads. g Lateral jumping distance depending on the height of lateral drag pads.
