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....

I do have A voltage regulator i bought from robotshop.I would be happy if it has enough amps to run the panda because my 7.4 Lipo can run Ezb and sensors,servos pretty good. If not I may upgrade to a light weight battery pack similar to what the e-bikes use.
Okay so I took back what I said that Roomba can't work out on a taller robot body....After I put in a few self tapping screws and tons of hot glue in the seem of buckets to make the body stronger, it seemed okay could not tip it over by hand! The First test with taller body was a disaster though,Roomba is working too good! the torque on those roomba motors are crazy good! I had to stay near the robot because the default cleaning program was to just ram into the corners of room and spin in a 360 turn just going nuts getting tangled in shoes and wires! Speeds are crazy too fast,all these can be adjusted with the Synthiam ARC software. So I will continue to Modify Roomba/Cylon. Adding the ultrasonic sensors should help big time.
Not too sure if I will put the robotic arms on it until I can buy more sensors ultrasonic or Infrared to add on the arms. I have 2 Ultrasonic now, will try one on it,s back and Front. Also run at half that speed!
Well ,I do think I solved my power problem so that I can run the EZB and the Latte Panda at the same time . I found an other battery from an RC boat .Not a Lipo just a NImh at 8.4 volts.Will use for EZB. Then on the Panda I can use high powered Lipo at 7.4 volts and has a high current rating.In testing the Ezb lasted longer than an hour! So re charging now and after will see how long the Panda will run.
I added a 12 volt lead acid battery that was from my e-bike. On the bottom which is not too heavy but just enough to keep the 4 foot body stable at high speed.will even stay stable after sudden abrupt stops.should be able to provide more current to electronics.
Okay, so following instructions from the Roomba hack video with DJ, I did some simple surgery on the Create 2 serial-USB cable,using the available header connection directly on the cable. I am now using power for the EZB from the Roomba battery at around 15 volts,no problems. Then only adding the RX wire and connecting to the EZBv4 TX output pin at D5 or 6? I forget which as the other pin is only for recieving data from the Iroomba which I dont really need now. Also EZ camera comes on so I can right away start remote driving the Roomba while watching the view on my big screen tv as a monitor. I can now finish adding the Cylon Chest and back pack pieces maybe the arms not sure on that yet .So here is the first successful test of the Cylon /Roomba. His head was removed just in case it failed and flipped over,causing any damage. I have 1 small lead Acid battery on the bottom which gives it enough stability to get to medium speed and stopping without tipping over. I think I will add my slightly larger acid battery for good measure. He does vacuum the floor,all the buttons that DJ and crew added to the Roomba plugin work great! Now I need to finish all the body parts and figure out how to make a script with adding sonar sensors to the middle of body. Next great challenge not sure how it will work,if Sonar needs to control Roomba H-bridge? I could also add the wires for recieving sensor data from Roomba infrared bumper sensors. 1 thing at a time.
