Explorer/Inspection robot from scratch

Hello,

I am new to robotics but essentially my end goal is to build something similar to the inspector bot (https://www.robotshop.com/en/pan-tilt-minibot-inspection-robot.html).

I have tried to read and watch as much as I can over the last week, but still not 100% sure what I need.

What I think I know:

I think I have decided to start with the Prowler 4WD Robot Kit, due to its greater ground clearance and speed, over the A4WD1.

With the prowler kit I think I need a Sabertooth Dual 2x32A 6V-24V Regenerative Motor Driver

and for my pan tilt with i think I will go with Lynxmotion Micro Pan and Tilt Kit with Servos (Black)

What I don’t know:

How do I control the rover with RC? The PS2 controller setup looks convenient and compact, but I assume there is a range issue compared to say a Flysky FS-i6X 6-10(Default 6)CH 2.4GHz AFHDS RC Transmitter w/ FS-iA6B Receiver? I plan to use this outside and in enclosed spaces like crawl spaces so reception is important to me.

I would like to control my pan/tilt and rover motion with the same controller, how do I do that? Can one joystick be movement and steering and the other pan tilt?

Do I need something like Lynxmotion SSC-32U USB Servo Controller to actuate my pan/tilt?

Batteries:

I saw on one of the superdroid robots that they used dewalt 20V batteries. This is ideal to me vice buying battery packs, bc I already have lots of dewalt batteries and chargers, while I have nothing for RC battery packs.

I assume they were using something similar to this that I found on Amazon [Battery Adapter for DeWALT 20V Max 18v Dock Power Connector 12 Gauge Robotics] (https://www.amazon.com/battery-adapter-DeWALT-connector-robotics/dp/B07HKGM78H/ref=pd_ybh_a_1?_encoding=UTF8&psc=1&refRID=KVMTK9JPQY55JFRHQ1QQ).

Does anyone have experience with these and can share a recommended brand or pros/cons of using dewalt batteries?

Any recommendations or insights welcome. This will be my first foray in to robotics, so any helpful info is appreciated.

Hi @Premierwheelman and welcome to the forum

To control the pan/tilt servos and the sabertooth , the SSC32 would be overkill.
I’m sure, there are dedicated 4WD robot controllers with RC-support, but I know there are many RC-multicopter-controllers, ready to control lots off servos and even autolevel the camera.
In any case, it’s likely you have to adopt the software to your usecase.

Usually an RC-transmitter can add some potmeters to control pan/tilt. No need to use the joysticks for that. (I will check the abilities of the Flysky later and report)
edit// the Flysky already has two potmeters installed :+1:

Regarding DeWalt battery holder Check this first
In case you have access to a 3D printer…

The Prowler comes with 12V motors, not sure if they survive 20V DeWalt-power for long…
