I used three [ http://www.ebay.com/itm/37GB-550-555-DC-Brush-Gear-Motor-37mm-DIA-DIY-Robot-Toy-Car-DC-12V-24V-/272307306999?var=&hash=item3f66c7c1f7:m:mbV9RsQ6UH4tPhU1tvlyfAQ ] this type of motors to drive the robot and three [ http://www.ebay.com/itm/3PCS-DC-3V-High-Speed-Electric-Mini-Motor-Micro-K20-Motor-for-Toy-Car-Model-DIY-/252579677724?hash=item3aceec061c:g:uqIAAOSw-CpX-Q5l ] this type of motors to clean the pole and one [ http://www.ebay.com/itm/6V-DC-160mA-100RPM-Dual-Shaft-Car-Toy-Reduced-Gear-Motor-Yellow-c13-/251525941428?hash=item3a901d48b4:g:uIsAAOSwsB9WDdVl ] this type of motor to rotate the plate attachment back and forth.
well it is about 8cm/sec regardless of cleaning or not. I think that is because the high power driving motors i used. (35kG/cm @ 12V) anyway the speed can be changed easily via the code.
well, i made this robot mainly to clean long length, vertical poles that hard to be close. the three motors in the last photo is to clean (or buff) the pole. to eliminate the non cleaning space those motors are rotate (actually the plate attachment that motors are fixed is rotate) CW and CCW (back and forth) in 60 degrees and these three motors are connected parallel to a H-bridge. this rotating action is done by the small plastic gear motor (yellow color) and is driving with another H-bridge. as you can see that three driving wheels are drive separately using three H-bridges. so, one another H-bridge is spare. I'll try to make a video of this and a connection diagram too. any more questions are welcome. cheers
