Delay checking with MFC Timer With MFC timer we could perform a sampling on the motor encoder in a very accurate time. We used this feature in order to measure the time delay from the moment we called the controller to start the motion until the moment the motors actually began to move. We set a timer in the code before calling the function to move the motor and we started sampling the encoder every 5ms. We couldn ’ t get more accurate checking with this method, because the minimum time between each sample can ’ t be lower then 5 ms. This fact we discovered by our self, by few experiments. So we did a linear interpolation between the points in order to get the delay time.

Delay checking with ACS Tools Using ACSPL you can create a data collection of the motor motion, the data collection does as we did above it sample the encoder every specified time, but using data collection feature you can get sampling every 1 ms, so implement a data collection code within our program, and the results showed the 2 ms was correct, and we also discovered there is a 2.5ms delay between the sampling time until the computer gets the sampling results.

For better view of the project results, we created a graph output program that gives in real time the graph of the football player motion.

The path is defined by an array of up to 32 mixed straight line segments The motion starts at the present position, accelerates to the specified vector velocity, keeps that velocity until the last segment, and then decelerates toward the end point of the path. This motion gave us the best solution for creating our motion profile,this motion is very flexible and can serve many type ’ s of motion.

We decided to set 3 points in a linear line, the middle point is specified point which the motor had to go through in specified time, while the other two points on the sides, helps us to gain control on the velocity. The motor will achieve in the middle point. This idea was based on the assumption that the ACS interpolation was good enough And will make the motor to move through these points accurately.

The idea of the numerical interpolation came to, after having problems to achieve good results using the ACS interpolation. We used the popular Divided Distances Interpolation. This interpolation creates a polynomial function of forth levels: The inputs we used were: f(0) = 0 the starting point position. F ’ (0) = 0 the starting point Velocity. F ” (0) = 0 the starting point acceleration. f(delta_t)) = X the specified position point in the specified time. F ’ (delta_t)) = V the specified velocity point in the specified time.

In order to achieve more accurate velocity in specified time, we used the technique of the 3 points, combined with our interpolation. Whit the combination of both techniques, we achieved good results in position and velocity. The results were showed errors around 300 to 0 counts in the position, and around 10 counts/msec in the velocity. Those results were taken in hard paths as the tests before.

We have fully implemented the project goals, and also added some additional features. Created a motion profile for the football player Overcome of the delay of the controller. Succeed to get reasonable results on both axes. Gained knowledge of working with Real-Time systems. Provided an easy class to control the motors in future development Created a graph viewer in order to see the last path of the motor. Gui designed especially to be attractive,intuitive and easy to use.

There are few enhancements that can be done in the future and they are: 1)Improve the interpolation by considering the acceleration limits and the response to steps. 2)Replace the controller with a new one, for two reasons: a. The existing controller can handle up to two player ’ s rows. b. The controller can ’ t change movements on the fly.
