Introduction: Budget Friendly Home Made Rc Bobcat With Ground Ripper and Solar Update Video

About: Me and my daughter just tincker together, and figured we'd share them with a crowd that may enjoy them like instructables.

Don't Forget To Watch My First Test Run Video And Solar And Ripper Video!

As a child I loved construction toys, wasn't never into the plastic ones. Always metal and as I got older it turned into rc construction toys, but they where all pretty much plastic found a few all metal fully functional rc construction toys, problem with them there all about two thousand and up. So I came up with this on a budget of four hundred dollars. I hope you enjoy and like it.

Step 1: Parts List

4- Traxxas rc tires

4- Wormgear motors

2-motor controllers

1- Rc Transmitter

4- Linear Actuators

2- 6 volt batteries

1- Wood Of Your Choice

1- Jb Weld

2- 6 volt solar panels

1- solar charge controller (small one)

Scrap Pieces Of Steel ( Thickness of your choice

Step 2: My Frame

Basically i cut my frame out of Home depot chalk board wood. It's 24"x7". I painted it with a black acrylic sealant for a water proof finish. Reason for the wood is it's readily available and when i wanna connect a camera its fast.

Step 3: Motor Positioning

So I'm using 12 volt 100 rpm worm gear motors. I suggest you trace the motor face out and create a template first and then put them on the side of your frame before drilling. Position your motors to your own positions.

Step 4: Writing and Wheels

Ok after your frames ready motors mounted, wheels are on time for wiring. I'm using two Sabretooth 2x25 motor divers. Coupled with a distribution block and two five amp fuses. One motor driver dives all the wheels in tank mode, and the other motor driver controls the linear actuators.

Step 5: Lift Arms and Actuators

Ok frames all closed up, time to make the arms starting with the actuators, I'm using Actuonix P16-P linear actuator with Position Feedback with a 256:1 gear ratio. The reason you wanna get the actuator with position feedback, is because that position switch won't allow you to over extend and break the actuator. My lift arms are made of out of half inch aluminum c channel from Home Depot. Cut them to my desired length. I used threaded rod, washers and nuts to assemble the front end of the lift arms were the bucket goes.

Step 6: The Bucket

The Bucket was made by a friend, its welded together but you can make a bucket from glues screws or whatever. Welding isn't necessary.

Step 7: Ground Ripper

This ripper is my first prototype. I cut it out with a dremmel and used a old rc swing arm. And another linear acuator .

Step 8: Solar Panels and Charge Controller

When it comes to the solar. I'm using two six volt solar panels. Connected in series to give me twelve volts, connect it to my charge controller and straight to the batteries. (Note) solar does not keep batteries fully charged but does improve run time significantly. Thank you for stopping by.
