Well this is just one of three projects that i have been tinkering with to get me prepared for the real ROBOT stuff.
The Main Chassis :-
Iis an old Maplins R/C 4X4 Monster truck that I bought 16 years ago and has sat in my daughters' bedroom for many a year.
Project Road Map:-
The concept is to make the truck as autonomous as possible without having to resort to using a microcontoller . it must also DO more than travel across the floor.
A} switch on Headlights & tail lights if it goes into a shadowed area.
B} turn on indicators if turning left or right
C} turn on Reversing lights if reversing and sound bleeper as warning
D} on approaching an object turn on wig/wag headlights
E} on closer approach turn on siren & turn on Police style roof bar lights
F} automatically reverse away on acurved course after a collision, pause and then go forward again.
G} During the pause Brake lights should come on
H} Stop immediatly if any wheel is in danger of going over a precepice and drive away from the Danger
I} all of this hopefully with analogue sensors and NO microcontoller
10mm LED's bright white installed on chassis as Head lights.
Amber Flashing LED's as Indicators mounted on the body work,
Red LED Brake lights fitted as are the Red RED tail lights,
Reversing LEDs are Bright white.
LDR sensor fitted into the "blower" housing on the hood (the shiny bit in the middle )
Darkness sensor with 9V relay built & tested
Headlamp Wig-Wag (Flip Flop transistor circuit) built & tested
Police style Hazard bar circuit designed & tested.
In the above picture you can see the LDR hidden in the "blower" shroud & the police light flashing RED
In the picture below you can see the Police light flashing BLUE
too much to list LoL, but the research and breadboarding is fun BUT waiting for parts is NOT
Well this site obviously :-}
Talking electronics.com site & owner for making my research that much easier and sharing the circuits for free !
To my long time friend Mark, owner of http://www.e-repair.org ,for his long standing patience with answering dumb electronic based questions when my brain refuses to remember stuff I did 40 years ago.
Brentford Radio Control for the helpful hints on Police colours & stickers
Last but by no means least Camala (my lovely wife of nearly 30 years ) for helping me come to terms with my failing health and indulging me in this "new" hobby. Also to my two daughter Samantha Jane and Megan Annalise for loaning me the Truck and "Dad can you talk about something else PLEASE "
