CableCam - Failed Concept

Description

<B>This Is A Proof Of A Concept - And First I Must Admit, I Didn´T Reach The Target - Not Even Half Way! But I Learned A Lot And Will Reuse Some Of The Parts For A Changed Design. And Maybe This Helps Some Else, Thinking About Creating A Similar Tool, Too</B> (Edit: In The Meantime I Created A Camera Slider, Using The Parts That Were No Longer Needed Here: The Stepper, Stepper Driver, The Arduino, The Shield And A Battery: Https://Www.Thingiverse.Com/Thing:3042730 ) The Primary Idea Was To Create A Kind Of A Programmable Cablecam - With An Arduino As A Brain And A Stepper-Motor To Move The Thing. There Should Be Foldable Arms For The Rolls And And A Simple System Of Two Rods To Carry A Small Camera-Gimbal, That I Use With My Copter. So The Basics Were Designed. Then I Tried Several Sketches To Turn The Motor Forwards And Backwards A Different Speed. Next I Found Code To Read The Pwm-Signals From A Receiver And Finally I Put Thoose Lines Together And Got A Sketch, That Lets Me Move The Thing Forwards And Backwards By Pushing The Stick On The Remote. Https://Youtu.Be/U8Bpidyfe8K (The Thing In The Video Is Not Leveled Because There Is No Camera Installed). And That´S Where I Stuck. The Motor Is To Weak Although I Tried Higher Voltage (12 V Instead 2S-Lipo) And Adjusted Vref. For A Faster Speed I Need A Bigger Wheel Which Means A Longer Lever And Less Strengh … Now I Think About Using A Slow Running Brushless Motor (About 600Kv) And A Car-Esc. For A Simple Design Like That, There Will Be No Need For An Arduino - But There Will Be No Simple Way To Make It Programmable Either. (With The Stepper-Motor There Was The Idea To Count The Steps While Moving From A To B).
