Excellent platform for DIY robotics. Four wheels give stability, robustness and nice differential steering. Smart structure with interlocking motor/wheel sets, fast to assemble and repair if needed. Not really durable, broke one by dropping from table. This kit is so cheap, one can have another for spares.
Smart design for battery location between the chassis plates frees a lot of space and mounting holes for sensors/actuators/whatever. The best product of its kind IMHO at the moment of writing.
4 cells is not enough if you want to use Adafruit Motor shield and NiMh's. The regulator drops off 1.5V so you are left with 4.5 or less - no good. Double the number of cells to 8 and you have power to play. Tried with very good results. Have more duration too.
Highly recommended for basic robotics.Just received this in the mail a few days ago, took quite a while to get here but for the price I could def wait. upon opening it everything was very nicely packaged. I currently have mine hooked up to a arduino uno and seeeduino motor shield, FINALLY a small affordable base for beginners and advance hobbyists, the only thing that sucked was while building this i had 2 of the 4 long spacers come with the product unthreaded so i had to replace them with second hand ones and lastly 2 out of the 4 motors work actually only one works at 100pcnt the other one works when it wants to, maybe i had a bad batch but i'd like to see if hobby king can replace the motors, over def worth every pennyvery good for assembly of prototypes.Great kit for the price, everything included. Rubber tyres are great, not hard plastic like I've got from another wendor on eBay. The only drawback - no encoder. But like they say - "The possibilities are only limited by your imagination."
