|
| | | Hi, I have some questions about usage of multitasking in robotics. I think its necessary, because it simplifies programming. Instead of breaking down actions in small pieces and check sensors in between. For example: driving a square and watching (...) (20 years ago, 9-Jul-04, to lugnet.robotics)

When the robot hits an obstcle, he gets back and turns. How do I (...) (20 years ago, 18-Jul-04, to lugnet.robotics)

| | | | (...) A useful technique (which doesn't really require parallel threads) is called a "State Machine" (also known as a "Finite State Automaton" or FSA for short). The idea is to list all the 'states' the robot can be in and to assign a number to each (...) (20 years ago, 19-Jul-04, to lugnet.robotics)
