I have always liked the idea of using ready made products. I would imagine that Master has more to do than to monitor the forced exercise of his/her toy. To t his end I would use a computer to set the timing of the exercise. The computer would measure the amount of time that the toy would need to move in order to gain pleasure of avoid adverse stimulation (supply your own concepts). Set a course where the toy may complete the circuit in a reasonable period of time. I like a country setting myself. Place The signal at either end of an orchard. Place the toy in the middle of the orchard where she/he can observe the signal. Place the safety switch at tow known locations. The task is to go to the correct switch when the signal indicates in the appropriate amount of time. This is a simple device that will have the toy walking/running between several locations without having master monitor.

Should the toy make it to the switch in an appropriate amount of time then there needs to be a reward. Perhaps a vibrator that will stimulate to orgasm could be activated after each time the switch is pulled.

Whould the toy not make it to the switch in an appropriate amount of time then there needs to be an incintive. I would think that a modified dog collar would work well. The probes could be located so that areas of masters choice would be zapped if the switch is not thrown. Could you imagine having the toy dancing all over the orchard trying to accomodate that little active jolt. Either way the toy would want to meed the exercise needs as given by the master.
