Can anyone think of any major issues I might come up against?
I'm trying to get this thing as finalized as I can before I head of to Radio Shack with my 50$.
The idea is to use a laser pointer or laser pointer cluster that reflects off the floor into 3 laser sensors, which it then uses to triangulate the laser beacon's position and distance. It will then move to where it thinks the beacon was. This way I can send it through doors while I hold them open, etc.
I think I understand what the OP wants.He want to hold a laser pointer in his hand and be able to point it to where he wants the bot to go.Chelmi.
[...] I'm figuring it could figure out the distance by measuring time from pulse one to pulse two, similar to how imaging equipment measures distance by measuring time between pulse sent and when the pulse was received. If there are any design issues, just tell me.
Could I run this bot using voltage-type readings (I.E. more distance= higher Resistance) from a photo-resistor like circuit?
Is there a better way to do this all together?
Here's my solution to sunlight issue: Use a sensor that detects mostly red LASER light (which I was trying to find earlier) and/ or have the LASER pulse at maybe every 0.10 seconds. This way it can identify between sunlight (non-pulsing) and LASER light (pulsing). What are your thoughts on this?
Other wise,the US sounds like I good idea. However, I'll likely will be using this in a very crowded, noisy place. Would this interfere with the US sensor?
And could I use this like my original idea; have the emitter in hand and point it where I wanted the robot to go, then turn it on for a few clicks?
LEDS can detect light? Could you elaborate on this?
Also, how would I run a 9-volt PLC (an RCX 1.0, to be exact) off of a lawn mower battery (around 12 volts by 234 or so AMPS). I figured I could use a transformer to lower the Amperage, but that would increase the voltage, which (I think) would still burn up the PLC.
Finally, could I possibly re-name this topic to something a little more suitable?
