Fig. 4: Extending water layer-induced drop bouncing for robot application.
From: Liquid metal droplets bouncing higher on thicker water layer
a Construction of 3D printed robot equipped with four LM droplets at its feet. b Optical images show the jumping and rapid sliding of the robot equipped with LM droplets. c Comparison of jumping height and sliding velocity for robots decorated with and without LM droplets. The scale bar is 10 mm. The error bars for the jumping height and velocity were obtained from the standard deviation of five replicate experiments.
