Wheeler Chair Robot
I saw that last year somebody had built a wheel chair robot?. My idea for the new Robot will be as a stage mascot that can also pretend to play the drums on stage. My brother has a live Metal band every Saturday night and most of the time we have trouble with no drummer showing up. We end up using a Drum machine instead with the 2 other guys on real guitars and singing. So Terminator will be able to move around and substitute behind the drum kit with the Live drum machine signal activating terminator arms at the drums. Also need him to move around in a wheel chair , so is anyone out there that has done this wheel chair hack, looking for suggestions on power/motor controller connections etc...should not be too hard just larger than I'm used to building. This is a youtuber that bought what I just bought,takes a month to get from China and we are building the rest of the Endoskeleton to integrate in wheel chair....

Could be power related for sure. I find sometimes they behave funny when not getting enough power - and a bad ground could do it.
Yes, agree DJ, I am sharing the 5 volt regulator with both sonic sensors and the heartbeat L.E.D.'s seems to be okay on power but then the grounds are getting shared all over the entire system. Sometimes a working servo can cause disruption on the grounds. To solve that in the past I isolated the power source for the sonar with a pack of double A batteries.Only 1 ground wire for both sensors.
Yes ,one thing I really love about Synthiam ARC like say you are just starting out to program any robot, not really sure how to write a Javascript or even Blockly script. You can pretty well use a pre existing program in the Synthiam cloud to download for your "any" robot design. Just make sure you set the limits of your servos so you don't get any sudden movements going the wrong way.Save the servo profile to Start up everytime you open Arc. Then you can have fun for example I use the revolution Hex 6 sample program from the cloud, save it as my own,try out what all the buttons do like on the mobile interface joystick window, try the attack button, walk,dance,wave etc...the chances are it will work with your servos! So I had Mr Cy wave at me,attack me,move forward everything worked then you can go into the Auto Position movement window and modify how far,fast the servos move,add custom movements and delete the actions and servos that do not apply to your robot...I tell you what ,I have never had so much fun with a lockdowns hobby!:D
Another setback today, lost the hand cannon Star L.E.D. seems they can get so hot even with the back heat sink ,if the driver board is too close the Circuit board can melt the wires off! It happened to both my driver boards. Sollution now is to buy more expensive driver board with longer wires. Really sucks as that was the most fun part of robot. To be fully self aware with the room and detect movements, lift arm and fire the 3 watt super bright flash, add gun sounds...ah well.
I have better ground distribution now for all the sensors, going to neatly tie wrap all the wires away from chest. Also working more on visual responses to when it see me I will try to teach camera my face to recognize me.Get some conversations going.
Wow you're making a lot of progress lately! All energized
Hey Thanks DJ! Of course I would not be able to have all this fun without all your hard work and dedication to making this hobby possible for any one that always wanted to build one or buy one ready to go,easy to program! Well, I have found the driver board that is an upgrade for my star L.E.D. blaster!.... driver board 3 watts
Oh man did quite a bit this night, ready for a rest as it is 2:30 AM. I am so tempted to let the Cylon/Roomba loose out in the main living room,clean some dust! Too much noise for now,people sleeping upstairs, LoL! That left servo is an older one, does buzz but still works good.
