Figure 1From: Active modification of the environment by a robot with construction abilities Vertical expansion properties of different types of polyurethane foam: the blue line shows the expansion rate of one-part type polyurethane foam, while the red line shows that of the two-part type. This test measured foam ejected at a height of 200 mm by our robot. In the experiment, humidity and temperature were kept at over 30% and 20°C.Back to article page
