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 bumpers
Different behavior of the multitasking:
1. Like the RCX Lego software
Sensor will abort the running task, execute its own, but never return to
the interrupted task.
2. Real Multitasking
Each task runs independent from each other. Higher prio task will
interrupt another task. When this task is finished, execution returns to the
original task.
I'm not shure is it the behavior of BrickOS? How BrickOS handles sensors, in
respect
of task switching?
Which concept is better, abort the task and execute the new task or interrupt
the running
task and go back after finishing the high prio task?
Thx

If the sensor just indicates something that you need to make a small adjustment for (turn away from a bumper push, for instance), then returning to the (...)

| Hi, how does BrickOS handle the following situation? Its a path follower robot with bumpers to detect an obstacle. When the robot starts it seeks the black path and follows it. When the robot hits an obstcle, he gets back and turns. How do I (...) (20 years ago, 18-Jul-04, to lugnet.robotics)
