What Do I Build Next? Some Assembly Required? Part 1 of 4

What Do I Build Next? Some Assembly Required!!! Actually, alot of assembly was required. I'm not kiddin'...My fingers are numb. 6.0 Hours to piece together these two tank chassis'. (Two of two different kits purchased from Banggood on February 26, 2019 which finally arrived on March 30, 2019). The project is in two parts, the assembly and the electronics/BRAINS. This kit had no documentation what-so-ever... an opened box of parts...screws, nuts were loose in box and in torn open shipping bag?..Customs or the Post-office? At least someone folded the bag end over and applied some tape.

I'm glad to actually had chosen to assemble this one second.

This is what website showed:

This was my kit:

Did I say,...in previous projects.... I hate removing the blue film

Using knowledge gained from the first kit, and from one picture in the item description web page, the second TANK was assembled. It had 4 drive wheels attached to the motors and twelve follower/free-spinning wheels that needed assembly. I chose to assemble ALL 16 wheels first... The wheel assembly pictures from my first build helped with this build's assembly but not totally. I did had one blunder... I actually disassembled one follower wheel assembly to install an axle but later determined that my "I guessed wrong...was actually correct, and I needed to swap the axle and hub back to previous orientation. I actually got the assembly each each wheel down to 2 minutes....but after 40 minutes my fingers were useless.

First step, for me was to organize and identify my hardware

second, remove the blue film

third, organize parts for wheels, followers, and drive sprockets... look at pictures that are available

forth, attach sprockets, motor couplings, and threads to each assembly

Fifth, attach each assembled motor assembly to chassis.

Well, that's "some assembly required"... stay tuned for next installment when electronics/brains are installed...

I want to use a Raspberry Pi, PiCamera, Webstreaming, L298 motor controller, 7.4VDC-12VDC battery, some Python code.... and maybe magic... from adapted Kookeye or Osoyoo Raspberry Pi Robot Kit that (I previously purchased) uses the PiCamera for live video streaming while using the L298 motor controller with PWM..... stay tuned
