robo rad
Resolved by Dave Schulpius!
This was the test done in the kitchen but I have video from a few days ago with a bunch of EVP sessions done at the Grave/memorial stone where the owner of the cottage burned himself to death in his mini-van, still going through the audio recordings and video, was a successful investigation, in the night we had bad thunderstorms and only got the day time footage. EZ Robot system performing Excellent outdoors ,I just need to make the script available for my cell phone in the EZ mobile phone app. Having trouble with ultrasonic conversion, I need to add the ping command to the current laptop script for it to work on mobile phone. I will add the current script for public anyone to use if they have a tank/H-bridge and ultrasonic sonar robot. Please add your own improvements modifications, I am learning something new everyday with the scripting but still new to it!
Maybe some laser diodes?
Bounce them off some mirrors?
Oh ya, those green burning lasers from China,can pop dark balloons!
Haha yeah i've seen that, funny how they can only pop black balloons and no other color. Good for engraving things though.
But you can create laser light displays with them i think, and use them for robot navigation, etc.
This is a good link about how to use lasers for robots, interesting read. Get some reflective diffraction grating, shoot a laser through that and see what happens.

updated the Battery and lighting systems as it was not good enough before for wandering around outside at night. now with the 7.4 Lipo 5000mah and 2 nimh 8.4 for the motors and lights, this little guy can show everything on it's video camera ,in pitch black night! I had it roaming around the campground almost the whole night at the end there!
Looks awesome at night, loved the on board footage, she travels over the ground really well! : )
Oh nice work with the batteries, whats your run time roughly now?
I am still experimenting with which battery to use for the EZB and the H-bridge motor controller because the H-bridge needs more juice for the motors but then also the EZB is running it's own Wifi server and video feed from the cell camera along with all the other data transmitting to my Laptop.It seems that using the 7.4 5000mah Lipo battery has never died on me yet hooked to EZB and the motors will die first on the H-bridge Nimh 8.4 volt 3000mah battery. (should buy another Lipo probably) The EZB with LIPO is superior to the Nimh.I will try switching the batteries to see what happens but the problem comes with Lipo will no longer have the early warning battery status from the EZB if it is on the motor controller.The robot was still running after 5 hours and if the motors did not completely slow to a crawl,The EZB seems to run forever so far LOL! No low power warning ever came yet! I am using the Venom brand Lipo with the new all in one balancer charger,can also recharge the Nimhs and Nickels. One further note is that I don't drive the wheels at full throttle I will often run at quarter speed and stop/pause for many minutes while listening for sounds and observing video,so this helps to keep juice in the motors.
Would continuous servo's be a good idea to drive the wheels instead of running them from a H-Bridge?
But wow your run time sounds really good, but yeah the ezb is very good with power consumption i've read. : )
Venom are good, i use their lipo low voltage alarms.
Wow great idea again! I should try newer servos as those can connect directly to EZ B right? Then I could use the H bridge for other control motors in the head and arms, dart gun!
