2.0 out of 5 stars Arrived Broken 28 Mar 2014
Verified Purchase
First it arrived with the main body part broken... Then when I used it with batteries they kept exploding when I used the supplied battery compartment... also, some of the holes are not lined up properly and an incorrect number of bolts was provided...

I've glued these directly into the base of my robot, the caster has a lot of swing which results in a small delay before the robot straightens out.

4.0 out of 5 stars Item matches picture exactly and met expectations. 14 Mar 2014
By R. Pries - Published on Amazon.com
Verified Purchase
The item was well packaged and everything in the picture was included. Note: There's no instructions in the picture, so don't plan on getting any. It was easy enough to assemble without instructions using the pictures. There were also extra nuts and bolts provided. I believe I had one extra long bolt, and a number of extra smaller ones, including extra nuts. Also, the clear plastic body piece and the encoder wheels are covered in a protective paper type material. In the picture you can tell they assembled the car and then took off the paper. That is why you'll see the brown paper under the items in the picture. It comes off easy, meaning it's not glued or using any strong adhesive, but does often rip when you take it off when it encounters a hole or other cut-out piece. So it takes a few minutes, and doesn't just come off in one pull. Once you do this to the encoder wheels, the wheels are entirely black, and just have notches or cut-outs to be used. I'm not exactly sure how these encoder wheels are designed to be used? Once assembled I wired it up with an Arduino and a H-Bridge Motor Driver (SN754410) and had it driving around with per-programmed instructions within the day. I don't think the 4 AA batteries could power the motors and the Arduino, but the batteries did provide plenty of power for both of the motors. Or not my Arduino Duemilanove anyways... which I believe needs more then 7V to keep it happy. Good enough for a quick little project \ learning experience. Would have given it 5 stars if the front caster wheel turned a little better and some of the tolerances with things were a little better. But overall it met my expectations and worked as intended.

5.0 out of 5 stars You don't buy these because they are the best, they work and are cheap 5 Feb 2014
By Chris J. Albertson - Published on Amazon.com
Verified Purchase
I gave this 5 starts not because it is the best robot platform. It's not. It is cheap and very simple. It just two cheap motors and plastic wheels and a very cheap plastic "body". The encoders are a disk with 48 slots that mount to the wheel axel. So you get 48 counts per rev. BUT you need to buy the IR detecters. for detectors buy the "HY301-21" optical switch and connect it to the interrupt line on an Arduino and measure the microseconds between the slots on the disk.

Note this robot will NOT do anything at all except drive in a big turning arc and crash into wall. Not until you add a small computer to control it, some sensors the encoder detecters and write some software. This is just the basic platform with no "brain" no sensor and not even all the parts you need to make the wheel encoder.
5.0 out of 5 stars Quick robot kit! 9 Aug 2014
By D. Richardson - Published on Amazon.com

For the price, this is one of the best kits that you can purchase for building a basic robot. I let me 8 year old daughter do most of the construction. We are adding an Arduino with the Motor Shield and a few sensors. Great school project. There are a lot of holes for mounting things. The one thing I would say, the holes don't line up for the Arduino, so I am making a custom mount that will line up with these holes.

it is a good start but its what was advertised
4.0 out of 5 stars It works great for small robots 30 Jun 2014
By ADavies - Published on Amazon.com
Verified Purchase
It works great for small robots. I build an Arduino obstacle-avoiding robot with this chassis. The motors seem to draw a lot of current, which required an additional motor shield for the project, but otherwise it does the job well.
