Robot auto recharge

Tomvn

Hi, First i had to thank to Tracy Allen and Mike Green and all poeple here to help me·finish my project. Robot auto recharge· used· Bs2 and Bs2e stamp···used infrared led·and Ping sonar··to localed the charger so
the Robot can recharge·by itseft ,

Hi Jax

i just draw simple but exactly what i have done my robot and charger

the robot· had more than that it have the· temperature sensor sound module and bluetooth module·but i dont had much time to draw everything

the picture·below is the ir detector sensor· on robot and ir led sensor at three led light at· charger

now· schematics and code all here.

@Timvn,

I'm looking at your code that measures the voltage using the RCTIME command listed below:

battery_statu:
LOW 8 'low pin 8
RCTIME 8,0,rct ' measure volt--
LOW 8
Vx=Cn1 / rct + Cn2
RETURN

I'm not sure what cap your using for this but should you not bring Pin 8 back to HIGH for recharging the cap for further measurements? Just trying to understand how you can continue to use this command when the cap is discharged. I did not see any command in the program to bring this pin back to high for a recharge. Please explain this for me. Thanks Tomyn

BTW: Great codding!!

Hi Jax,
i used 0,01uf cap , the code i got from Tracy Allen bog here the link he can explain better than me.

This is the reason I asked that question. In my Elvinator Project testing the eye movements using the RCTIME and a VR with a 1uf cap this is part of the code I wrote for the test and it worked perfect. I had to charge the cap and then discharge it when the readings were caught. I see in the schematics that the cap is always charged buy the layout thus allowing the bot to go into a sleep mode with out drawing too much current. I'll have to try this option out when I can. Thanks for the link. and here is part of my code I was talking about and my video of it working.

Main:
GOSUB checkeyes
IF RESULT =1 OR RESULT =0 THEN GOTO BUG ' if vr has no signal stop program
IF result <= 1100 THEN GOTO EYELEFT
IF result >= 2300 THEN GOTO eyeright
GOTO eyeright
GOTO MAIN

BUG:
DEBUG "bug found in VR READINGS = ", DEC RESULT,CR ' if signal loss stop routine
STOP


checkeyes: ' checking the VR location

HIGH 7 'use pin 7 to Discharge the cap circuit
PAUSE 1 'for 1 ms.
RCTIME 7, 1, Result 'Measure RC charge time. convert analog to digital
LOW 7 ' Recharge the cap for next round
RETURN

Hi Jax ,
what you gone to do with the eye movement , tracking the people?

Hey Tomvn

Beautifully crafted robot! I was just wondering what you used for the robot frame? Aluminum channels from a hardware store or an actual erector set of some kind?

Cheers!
