Lunokhod on tracks with remote control))...made from old parts...
brains PIC 12F629 driver L293 motor 2 motors and drives from CD-ROM tracks from the scanner (printer) the BATT from cellphones wheels - the bobbin thread from the sewing machine + a few other parts))
Awesome robot ukrnano, nice use of those old parts. It runs faster than I guessed :p. I too use those old cellphone batteries in my projects. I suppose you are using them in series which should produce approx.9-10 volts, does the l293d heats up after a few minutes of use at that voltage?
Also, cool PCB you made there, it even has a charging port in the corner!
Yes, L293 really heats up, but not very much…especially the really hot with frequent changes of direction(forward-backward) when the current is maximum, but this robot is not critical, unlike my balancing robot… …but the following robots I’ll be soldering the H-bridge of transistors, for better cooling…
