SZDoit 4WD Smart Metal Robot Car Chassis Kit for DIY Robotic Steam Platform with 4pcs TT Encoder Motor, 65mm Rubber Wheel, Speed Measure Encoding Disc

Easy to build. This was a super great value. Perfect for a DIY project.

Metal chassis smaller than expected. My phone is bigger. It comes with holes but have not found any that align with my Arduino. The included instructions manual is a one folded sheet of paper with pictures in black and white.The link to online instructions goes to a wiki page on github where I could not find instructions on this model C101. There no wires included for motors and no wiring diagrams. I would not order this particular model again but maybe try the tank chassis as there are better instructions for it on the site they mentioned for this model. The metal chassis seems sturdy and of good quality. I will probably need to drill holes to mount my arduino though. There was no online help as it seems noone has actually used this model anywhere. I found a video on wiring 4 motors in general and follewed it.

Very small chassis (doesn't fit anything but the battery). The manual is in Chinese and broken English hard to understand. There are no wires along with it to connect the motors to the battery pack. Does not come with batteries and doesn't accept AA batteries (still trying to figure out what type of batteries this battery pack is made for). I'd not recommend this product.

GREAT

Arrived on time but tires do NOT match. 3 tires are the same-these fit fine. One tire is very different—so doesn’t fit. Can’t use this to complete a college course project. So disappointed.
