Yes thanks Dave, it is working and is just a mess of wires for testing out the new stuff. I just love electronics and trying out new or old style circuit boards! Most people have no clue what I am doing until they see me organize the wires and boards neatly on the robots. Hey , I was just actually reading your B9 thread, some amazing stuff you are doing there! The old EZB-3 was going to be just like a classic museum piece on my shelf to just look at but I think it deserves to serve it's intended purpose to live on a robot. It will display itself on the robot's back pack. L.E.D.'s showing through clear plastic cover.Of course EZ-4 will still be the main controller.

I think I need a break, Took me many hours today to just figure out how to reverse motor polarity using old style relay board with 1 battery to raise the Terminator Left arm up and back down,  programmed with ARC Blockly. Next will be the wrist motor and finger grippers. When I get to building my other Cylon project I think I will stick with the HDD servos, wayyyyyy more easy than Relay board ,older motors for arms.I think I accidentally made a crude relay wired H-bridge to get the motors working without shorting battery.

Chopped a kiddy car in half to try wheels outside in Field. 12 volt high torque motors and wheelchair battery. Also adds the height I wanted.

At just about 6 foot tall I think he is about ready to cause Mayhem in the outside park! Still need to add the chrome paint tomorrow on the wheel base and the electronic turret machine gun just BB's of course and only for the cool sound effect.

Nice progress. I love the look now that you added the with to his lower section. I'm sure that will help with the top heavy tilting when he turns.

I may have missed it but are you using RC control for the drive wheels? If so what type of controller are you using? I'm going to be mobilizing a full size B9 robot and am looking for good RC options to control his movement. I'd like to keep the cost below 150 USD if possible.

No RC controls ,just going to keep it under ARC Mobile app control or full autonomous Roaming with all the new sensors helping out,EZ camera and possibly some tilt sensors to help the bot roam in the bumpy field areas. I am using 2 high power motor controllers at the wheels connected to EZB-4.These work great with my 15 Amp motors as they are now updated to handle 13 Amps continuously with 30 Amp peak power and all the way up to 30 volt motors.Very good price on these too...... https://www.robotshop.com/en/cytron-13a-5-30v-single-dc-motor-controller.html

Thanks!

Sounds like quite a cool robot you have here. When in roaming mode do you have some kind of "return to home area" if it go beyond a boundary? This scary cat would cause quite a commotion rolling down main street in town. LOL

That is a great question Dave and something I need to think about . I have lost control of my older robots before when roaming around outside All I could do was run after them when they would keep running across the field. If EZB controller disconnects for any reason there is no cutting off at the motors ,they just keep going with no way to remotely shut off. I will need some type of safety cut off circuit  like a drone uses to return to home.
