Emo Smart Robot Car Chassis Kit with Motors, Speed Encoder and Battery Box for DIY

Muy buen diseño y materiales.

Pretty much exactly what i was looking for. Enough holes to mount things. not perfect but was able to get 1-2 screws in. Chassis came scratched without the protective peel which the instructions said to peel off but that’s just cosmetic. As another reviewer said, the screws for the castor wheel are too small and go right through the castor wheel holes. I had to add some small washers which I luckily had. Btw you will need some additional wires to connect the switch.

Easy installation, and really fun to play with for a kid. Got one of these for a friend's kid, and after comparing the prices, this is the one I ordered. He absolutely loved it.

as expected

The item was missing parts required for it to function. Four of the screws were the wrong size and slid through the holes that they were supposed to be for. I used some of these spare nuts to hold those parts together, but there weren’t enough of the spare nuts to do it for all four locations. It also did not come with enough wires to connect the battery box to the switch and the motors. The item description claimed that this would be usable out of the box once assembled, and it was not.

Instructions were easy enough to follow if you thoroughly read them, can't just use pictures to follow along with. Screws for the "Hammer Caster" are too small and fall through the caster's holes, need to supply washers or larger screws. As others have recommended, the power switch location is horrible once everything is wired up, needs to be re-located. Also, make sure to solder on wires to the motors before you attach them or you're going to have a bad time putting them on.

As a gift for my friend, this DIY robot car has good quality mechanical components. It Included printed docs were fine for assembly. Overall recommend to everyone who likes robot car!

I bought mine to build a simple robot with my family. It comes with 2 motors which seem to be pretty standard, a switch which I did not need (switch was handled by GPIO on pi), a battery pack and the skateboard. The real problem here is the skateboard. Mine came with a bunch of micro fractures, however, I didn't return it because I was stuck indoors and wanted to finish the lesson. However, very quickly pieces of the skateboard started to break off where the fractures were located. Pros: * Everything you need to create a simple robot Cons * Skateboard was fractured new out of the box and ended up being extremely fragile. * No pre drilled holes to match the pi * Becomes back heavy when board and battery were installed causing me to need to install a weight to the front * Battery pack comes with traditional wires and nothing on the end meaning it falls out of the breadboard easily
