Here are some more biomorphic vehicles, somewhat inspired by the 1964 New York World's Fair. The bug man was in my dwelling today for regular maintenance and I was glad to report that I have not seen any pests in my house recently, unless you count me. The upper vehicle is called the "Trioptakon" and navigates by three "eyes" on front and back. It is slow but can carry a good load. It is outfitted here with banners for a parade down the Midway of the futuristic fair.
The lower one is the "HawkMoth" caterpillar vehicle and it can carry about eight passengers comfortably. Like its relatives in the "EsCARgot" category it can bend around corners as long as it isn't moving fast. And like all the EsCARgots, it moves slowly but precisely and is a fine carrier. The pointy thing mounted on the roof is actually a pair of sturdy extendable sensors with an antenna, which gives extra view as well as readouts of environmental threats.
Black tech pen ink on sketchbook page. Upper one about 3" x 2". Lower one about 5" x 2", December 30, 2016. The EsCargot says: Slow is good.
