Most of them would have developed the football robot using a microcontroller or using any complex circuit. Here is a simple circuit to design a football robot using simple logic gates. The circuit involes the usage of one OR gate IC and a motor driver IC L293D. The diagram is shown below for your reference.
Thus we can understand the power of logic gates from the above design..
