Re: What to do with autonomous

Greg,
Looking down upon the diamond pattern, the top sensor is labeled North, right sensor is East...etc. N-S sensors are 6" apart. E-W sensors are 4 1/2". The N, E and W sensors are 2 1/4" from the diamond center. However, the S sensor is 3 3/4". The system is about 4" high.

The mechanics say we cannot have the space in the dead center of the robot drive system and that are line-tracking system can be placed slightly forward of center. So, we consider this S sensor to represent center of robot (close as possible).

The distances and angles formed by the internal angles are subject to change but this is a starting point.

Assuming the sensor data can be sampled fast enough in lieu of the robots rapid movement, it is possible by examining the on-off state of the four sensors several things....assuming you understand the starting position and orientation of the robot.

Our team (4 students and myself) will discuss this configuration in more detail and compare its results to other sensor layouts. We need only a few data points along this path to follow it (parallel it) successfully...of course we need to do this in less time than 15 seconds. :-)

Regards,
Chuck
