Obstacle Avoiding Robot Project

I made this three wheeled robot in my last year of tech. school. I ended up making my own chassis out of a Radioshack project box, some aluminum pieces, and a clear plastic piece from an old Boombox CD player. I also designed my own circuit board and etched it in the tanks at school. The motors are servos hacked for continuous rotation. The wheels are modified RC car wheels and a ball bearing caster used for shelving units. The avoidance sensors [4] are Infrared SHARP GP2D12's and the ledge sensors [2] are also Infrared but are OPB704's. The purpose of my robot is simple: to avoid obstacles and drops. I named this robot Shadow Guide.

@krupasubhashini What info are you looking for specifically?

[shaquillec1]

can i ask the LED's you have on the front what did you use them for ?

[sk8rj10]

@shaquillec1 I mostly just used them for BLFNARs but I also used them to indicate which sensor was triggered, green for the front sharp sensors, red for side, and blue for the edge sensors.

hey there great job on this robot, small question... im working on a robot but having a hard time finding a good strong SMOOTH ball caster, what ur using looks smooth and great can u plz tell me where did u get this one from thanks

[sk8rj10]

@gmsemaan thanks, yeah finding a good caster is definitely a struggle sometimes, The caster I used wasn't all that smooth but it was strong, i found it a hardware store, i forget which one. Anyway I would highly recommend the casters from Pololu, we sell them at Solarbotics -> just search for caster, we had had good luck with the 3/4" sized casters.

we r doin d same project. Cud u pls help us?
