“The Droplets project is looking for at least US $10,000 to construct what looks like 100 robots. This isn’t to suggest that each robot actually costs $100: a full 50 percent of that $10k goes straight to the cast that has to be made in order to efficiently injection-mold the plastic outer shells. So, all that the CU Boulder team needs to make a full thousand robots is $30,000, since once the molds are out of the way and volume discounts kick in, the price per robot drops to $30.”
