Hey Community , i really don't do enough fun projects. As you may notice many of my projects have a utility function. Squeegee mops, jarvis vacuums, smart marine fish tank is... well smart lol. So this is just for fun and I hope others enjoy it. I have already contemplated using it as a demonstration tool to get kids interested in technology. . Dang it! This is just for fun , ok I'll try not to get to serious with this. My friend Marty was talking about being able to drive the power wheels around while his kid was in it around the neighborhood. Or if his kid was driving and got to far he's just a button click away from stopping it. We found a free power wheels that had seen some rough years and we gave it a complete makeover. It looks better than new, new Gel cells from power sonic , smart charging and more. I gave it a cool high grass stripe camo.pattern and gave it to his son for his birthday. I'll post a couple pics. He's on the fence about doing the further mods so i searched craigslist.org for another power wheels that had been loved a little too hard. Searching for something with space and power I wanted I set my heart on a f150 , Toyota 4x or jeep 4x4. I didn't find a 4x4 model but f150 was the next best as it had dual gearboxes with rs585 motors. Also a good gel battery and charger was included. Here come some pics...

Thankyou Sfoy , I would really like for this guy to be able to move. I am looking for my brushed motor controller and I checked the specs and now the specs say that the controller is good for a certain sized lipo. I will post the specs.
Edit: ok so I don't like the setup of the rc motor controller , they are loud and make crazy beeping noises everytime they turn on before they arm. So I am considering a completely different option. Either a relay or a H bridge serial controller from dimension engineering.
Shifting away from the H bridge , I received today the portable USB power router I purchased for 15 dollars. It is an older model from 2 or 3 years ago. That would be the first generation of 4G but not LTE. It connects to a cell tower for 4G internet, but also can interconnect 5 devices through WiFi. I'm going to test it out. Basically I could have the tablet run the robot but I could remote desktop from a longer distance without fear of being too far away. The obvious backup of course would be I just needed to get closer to the robot but I eventually want to go for some autonomy, but still be able to monitor everything from a distance. So anyways I did latency pings and speed tests with Ookla.
Great news , the servo city gearbox arrived for the steering on this project. It is a 7:1 ratio of the donor servos torque. All the parts a machined aluminum and very strong for their weight. I love that they put candy and mints in every order. Usually they do a hand written note as well. #servocitycandy
ServoCity Rocks! I just placed a $100 + order with them.
Do you submit picks and links to your project with them? Each time you mention them in a forum like this and give them a link to check they'll give you 10 - 15% discount on your next order!
I love the looks of those aluminum power gearbox arms! They look very strong.
I did try to bend the aluminum servo arms with my hands as soon as I pulled them out of the box and they are really stiff! They are no joke. They are physically thicker than they appear on the website. I did tag them on Facebook, but I will need to see about this percent off thing as I have a handful of their stuff and I love their products. No one else is making the things they machine. I love it!
They're stuff is the key parts of my B9 arms. Very strong, light and amazing. It's amazing how interchangeable their stuff is.
Alright , more parts arrived. This is to undo my epic screw up when I cut the last hub about a inch short. Here are the replacement parts and extras. The rod is the steering column that originally bolted to the steering wheel.
Ok so I put the bearings in the wheels and slid in the new axle. Perfect fit. Then slide the power wheels gearbox coupler hub on as well. I did this to ensure that the hub was centered when I drilled the holes and billed everything together. It wasn't perfect because I don't have a drill press but a hand drill did the job.
