 | | BlueTooth bad, Zigbee good

| (...) Bluetooth is actually very poor for embedded or robotic applications. It's a power hog, development tools are expensive (try $5000 minimum), true peer to peer modules are almost impossible to get unless you are a Fortune 500 company, and the (...)

To answer your question about headsets, I will speculate since I don't really know. But (...) (21 years ago, 3-Jun-05, to lugnet.robotics)

Has anyone seen, heard, or thought of a visualizing robotic simulator that works with LDraw models? In other words, you (...) (21 years ago, 24-Apr-05, to lugnet.robotics)
