Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
Customers report that the robot platform's motors are too weak and struggle to turn on hard floors. Moreover, the product comes with no instructions in the box, and customers find the anchoring system unsatisfactory. While some customers consider it a nice chassis for the price, others find it pretty worthless.
5 customers mention "Value for money"2 positive3 negative
Customers have mixed opinions about the robot platform's value for money, with some finding it a nice chassis for the price while others consider it pretty worthless.

Customers have mixed experiences with the robot platform's anchoring system, with one customer reporting issues with the mounting for the Arduino and another noting that the case wouldn't bolt together properly.
"...Also the mounting for the arduino is not ideal, no riser or screws just holes...." Read more
"...the holes until the head of the screw hits the plate, meaning no anchoring whatsoever...." Read more
"The case wouldn't bolt together unless I put tape on it to hold it together and 2 of the motors were faster than the other two so it always turned..." Read more
First of all, each of the 4 motors had bent up connectors and the provided wires were too small to connect and were too short to reach a top mounted arduino. The documentation blows, its barely even english and is pretty worthless considering it includes instructions for how to install led's and ultrasonic sensor that isn't included BUT they didn't bother to tell you the frequency's for the motors. Also the mounting for the arduino is not ideal, no riser or screws just holes.
I'm sure the next step will be getting some legitimate motors and hoping they fit the wheels.
It's a great looking chassis, and it has plenty of mounting points, including some that align with the arduino.
But: - The motors are far too weak. They'll drive forward and reverse but struggle to turn on hard floors, and absolutely will not turn on carpet. - The wheels don't fit quite right on the drive shafts, so you'll get a wobble.
For $50 I didn't expect much, and the laser cut metal chassis was probably worth that, but the motors are absolute trash.
Pros - reasonably cheap, plenty of room and mounting holes.
Cons - There were no instructions in the box. Took a bit of hunting around to find a pdf version on the internet. The wheels require a lot of force to get onto the axles. Probably a lot more force than the axles/motor can handle without some damage or warping of the plastic.
This is a nice little chassis for the price. The DC motors are a little weak using the included battery holder. I went with a 9.6v 1600mAh RC battery and the motors work a lot better. Instructions are not included but are easily accessible from the SainSmart website.
05/06/2013 - I am currently designing & assembling my own custom-designed robot which uses the SainSmart 4WD Drive Aluminium Mobile Robot Platform, so I am extremely satisfied with this product. I wonder if they make the same thing in a larger-size frame so that I can put some bigger wheels on it ?

Totally useless as-is. The screens that attach the frame parts to each other fall through the holes until the head of the screw hits the plate, meaning no anchoring whatsoever. As soon I noticed this I just stopped building and threw it back in the box.
I don't care how much it cost, you expect the damn thing to at least go together...something I will have to figure out myself, probably from my box of screws.
I was eager to get this and build it to be controlled via my xbox controller. However, when i assembled it and started it up it did nothing. The motors were so weak it wouldn't even move the robot on carpet, hardwood was okay but still not impressive. I bought some new motors and it works great. So if you plan on actually using this robot I'd advise getting more powerful motors.
There is no manual. The motors are far too weak. They'll drive forward and reverse but struggle to turn on hard floors, and absolutely will not turn on carpet. - The wheels don't fit quite right on the drive shafts, so you'll get a wobble.
Not a good kit for anyone not in possession of a multitude of proper fasteners and some serious technical knowledge.
Usually I list the Pros first due to the best foot forward and so forth but this time is a bit different.
Cons: 1) No instructions for assembly were included (manufacturer's website contains a very broken English translated copy). 2) Many screw holes that were supposed to be tapped were wrong size for included screws requiring user supplied hardware (larger, more aggressive or self-tapping screws). 3) Arduino board mounting is impossible without supplying additional hardware (standoffs and additional screws) and doesn't line up as well as it should. 4) Paint finish is uneven and poorly applied. 5) Battery box is of very cheap quality. 6) Motors have cheap quality terminals that are so thin that I had two break off during assembly. Expect to replace all four, thankfully standard Adafruit 6V hobby motors fit perfectly and were pre terminated with a length of hookup wire. 7) Wheels are not 100% round causing kit to "limp" under operation.
Pros: 1) The wheels are sturdy and have rubber tires despite being not quite round. 2) The aluminum chassis is also sturdy and somewhat well designed for it's use case. 3) 90 degree adapters for motors are thoughtfully designed to minimize lost internal space. 4) Kit is easily assembled and configurable when you have proper hardware.
