Hi,
The attached diagram is the base of my robot mower. The tank circuit is used to detect the electromagnetic field produced by the 555 timer with multiple loops of wires. When the field is detected, the robot will do a "U turn". Otherwise, it just go straight.
But my problem is, when i turn on the blades, it starts going crazy. It keeps doing U turn even at the center of the loops of wires. The electromagnetic field produced by the DC motor interfere my system.
I've used the shielding method by using the alluminium foil, but i was told that, that method won't solve my problem. Yes, it doesn't, i've tried it.
So, shall i change the direction of the DC motor so that they cut off each other?
Thanks!!!
