The BeachBot looking like a ladybug is the world’s first autonomous sand art robot that can draw the large scale pictures like a pro in the sand. It is made by a collaboration between Disney Research and ETH Zürich. The size of this robot is 60cm(L) x 40 cm(W) x 40cm(H). A 3 wheel arrangement with differential drive back wheels and a steered wheel give it enough mobility and a laser scanner is used to locate itself with the help of reflective poles around drawing area. Look at the video showing how the cute artist draws a sea turtle and a fish right out of Finding Nemo with aplomb.
