I built this years ago from the base of an old broken RAD Robot toy

It has, and still does, serve me well as a relatively "mostly all terrain" type test base for outdoor use.

It presently looks like this...

It is currently running off a Wemos D1 Mini Pro, and I have used many different control interfaces for it.  I am working with VirtuinoSE for it's latest GUI. 

It runs on a 12v SLA battery... which, while heavy, is easy to keep charged with a simple trickle charge solar panel, provides more than enough power and the weight helps with traction.

The motors and drivetrain are the stock (6vdc - now over driven, and plastic gears) from the original toy, and while very noisy they seem to "just work" so I haven't bothered to upgrade them... although I did have to "stretch" the chassis to tension the old rubber tracks and keep them from falling off when "tank steering".

It has a two speed "transmission" that I converted to servo control for remote switching.

One of these days I need to upgrade to a proper POV system (using a cell as IP Cam is too laggy) and add on an arm or something, with this servo converted VEX claw.

@gunner Nice bot base.

I know what you are talking about with the lag on the phone as a cam setup. I did it on a telepresence bot and it was no fun.  I would drive into stuff all the time.  I love the shifter mod.

I love that idea !

Makes me think about the old (still functional) Omnibot2000 I've got in the basement
