![]() | Harrison, Reid R. | Low-power analog VLSI visual collision detector | We have designed and tested a single-chip analog VLSI sensor that detects imminent collisions by measuring radially expansive optic flow. The design of the chip is based on a model proposed to explain leg-extension behavior in flies during landing approaches. A new elementary motion detector (EMD) c... | VLSI; Visual collision detection; Elementary motion detectors | 2004-01-01 |
