Feb 2020 Note: This is out of date, the V3 flockbots have had a significant redesign We believe that the robot as presently configured will cost approximately $500, not including shipping, taxes, or one-time costs (tools, etc.). In bulk the shipping costs should be less significant. Some of our purchases were at places like Radio Shack, etc., and no doubt there are rather cheaper vendors (edit this page to list some!).
The prices listed as 0 in this table represent these one-time costs or bulk purchases, such as screws, bolts, and washers. These represent significant laboratory costs, but the price per flockbot is negligible when compared to the costs of the other parts. The table is staggered to show major components of the flockbots and their constituent components. The quantity of each component shows how many sets of each of the staggered sub-components are in the flockbot.
The total cost of all listed parts below is $484.96
