Project by tonyandjody

 

In my line of work I spend a lot of time under mobile homes doing repair work. I thought it would be handy to have a camera I could send in to find the problem and maybe save a few extra trips under!

Step 1: First thing to do was make a stable platform.


I had some old rc car parts laying around so I started with 2 Tekno SCT 410's.

Step 2: Modification

 

The chassis were stripped and I modified, cut, stretched, and welded a new chassis with dual front ends.

Step 3: Functional steering, Main beam



The next step was to get it moving!
 
  • Step 1: I installed the main beam between the 2 shock towers.
  • Step 2: I modified and installed the 2 servo brackets for the steering

Parts Used
  • (1) 585458 Actobotics 15" aluminum channel (modified)
  • (1) 585470 Actobotics 90 degree dual side mount A (pair)
  • (2) 575148 Actobotics standard servo plate D (modified)


Step 4: Lift Arm



The next step was to create the lift arm for the camera
Step 1: I installed a servo gear box at the rear base
Parts Used
  • (1) SPG400A-CM-CR7 Actobotics channel mount servo gear box
  • (1) 585444 Actobotics 4.5" aluminum channel (Modified)
  • (1) 584494 Actobotics 90 degree hub mount bracket
  • (1) Radio Shack 1.5k potentiometer
  • (1) 585580 Actobotics flat triple bracket (receiver mount)
Step 2: I made the arm with bracing and attached to gear box.
Parts Used
  • (1) 585456 Actobotics 13.5" aluminum channel (modified)
  • (3) 545360 Actobotics 90 degree quad hub mount C

Step 3: I Made a battery box
Parts Used
  • (2) 585440 Actobotics 1.5" aluminum channel
  • (2) 545360 Actobotics 90 degree quad hub mount C

Step 5: Pan Tilt System

 


The next step was to create the pan tilt system
Step 1: I installed the top lift servo on the arm (keeps the camera system level with the base)
Parts Used
  • (1) 575144 Actobotics standard servo plate C
  • (1) 637110 Actobotics standard Hitec servoblocks
  • (1) 585422 Actobotics flat dual channel bracket
  • (1) 575124 Actobotics standard servo plate B

Step 2: Pan Tilt system
Parts used
  • (2) 525124 Actobotics Hitec lightweight servo hub
  • (1) 585584 Actobotics flat bracket B
  • (1) 585468 Actobotics flat single channel bracket
  • (1) 575144 Actoboticsstandard servo plate C 9modified)

 

Step 6: ?The final result is a good stable machine that will go pretty much anywhere i need it to!!!


Electronics used
  • 6 Hitec servos
  • Futaba 8 FG Super Radio
  • 10 channel receiver
  • Castle Creations Mamba Monster Xtreme
  • Tekin Pro 4 3300kv motor
  • Castle Creations BEC
  • Radio controlled switch
  • GoPro Hero 4 Session Camera
NOTE:
It takes a good deal of servo and radio programming to get it all to work, especially the 2 wheel, 4wheel, and crab walk steering!
