I ran into two minor assembly problems: 1) The holes for connecting the caster wheel were too large (it slipped right over the nuts that were supposed to hold it on). I didn't have any washers of the right size, so just I used a little bit of cardboard from a tissue box to fasten it. And 2) the battery pack didn't have the extra wires coming off the plug, so I had to chop the plug off. Neither issue was bad enough to drop my rating. I still think this is a very nice kit for the price. What I really like is that almost all of the parts will be useful in future projects. Review: This will keep you busy - As others have pointed out, this kit isn't exactly perfect. You will get all the parts you need to build this robot but no part of the assembly will be without a little challenge. I would not recommend this kit for a beginner to Arduino or to electronics. Nothing will work right from right out of the box. Someone with a little experience can massage this kit into a fun, working robot. If nothing else, you get a lot of good parts for the price in this kit. First I'll share some of the assembly challenges I experience. The Arduino and the motor controller can only be secured to the acrylic with two screws each. If you want more than that you will have to drill your own screws. For now I've opted not to and it holds together well enough. The battery case is meant for six batteries and only one hole lines up on the acrylic. I got around this problem by using velcro to hold the battery pack in place. The servo mount already had the servo arm mounted inside it but the screws were installed from the wrong side. The included instructions suggested a "fix" of installing a screw through the center of the arm and into the servo shaft which will work but I chose to also fix the incorrectly installed screws. For all this hard work you will still find that the screw holes in the acrylic do not quite line up with the screw holes in the servo base. Others have noted that the instructions for wiring the motor controller are incorrect. I found that to be the case in my kit too. However, where others found that the problem was the numbering of the analog pins was off by one, I chose to use the digital pins and reserve the analog pins for future use with actual analog devices. For assembly, the last problem I had was the instructions calling for connecting the power switch between the Arduino and the motor controller. This is not ideal as the result is that the Arduino board is always on once you have installed all the batteries. I cut the red power lead of the included barrel connected and connected the switch right after the battery pack so that once the switch is flipped the whole robot turns on. Others have complained about the rear caster needing washers or not quite lining up. Funny, but that was the only part of my kit that was without problem. Another reviewer, Perspicacious Consumer, pointed out that the ultrasonic scanner is "crappy." I agree. As for the included Arduino sketch, it stinks. It is a very poorly written piece of code that will have to be edited just to get the kit to work. At bare minimum you will either need to adjust the analog pin connections as pointed out earlier or you will need to change the pin values in the sketch. Also as Perspicacious Consumer pointed out, unless you enable PWM by uncommenting the analogWrite commands, your robot will run at full speed. I have hardwood floors in my house so I need to run the motors just barely above stall speed or the robot "peels out" by spinning its wheels in place without grabbing traction. There is one last significant problem I experienced with my kit. No matter what tricks I tried, I could not get the left and right motors to turn in sync resulting in the robot veering in one direction or the other. The kit includes shaft speed encoders but for some curious reason it does not include the photo-optical speed sensors needed to read the encoders. I've ordered a pair of speed sensors and will update this review with my results once they are installed. Despite all I've mentioned above, this kit is pretty fun and I've already started writing a custom library for it. It has a lot of potential and room for refinement and additions but it will require a little know-how and perseverance to get it going. ## Features - Easy Assembly: Simplified design structure for quick and easy installation.

I found it worked great. **Q: Where can I get the manual for the robot?** A: You should have gotten a small CD that included an example program, some short Windows word documents that explained wiring, and an assembly video when you bought the kit. I think some folks fail to realize that the video is included, since it is an .rar archive (similar to a zip file). Dallas Personal Robotic Group recently put out an alternative robot kit build video of this kit, which I believe is better. The link is https://youtu.be/d9TXThtSUNM . **Q: The dvd which came with this kit is blank, where can i download this information?** A: While this kit is a great deal, there are some technical issues. The kit is a standard first robot in many robotics classes. I found http://www.cs.columbia.edu/~sedwards/presentations/robot-car-instructions.pdf to have excellent instructions for assembly. Another source is a Youtube video from the Dallas Personal Robotics group https://www.dprg.org/ There are several ways to assemble this kit. I found the kit to be a good challenge for a first step in learning about robotics. The first link is my favorite because it explains the Arduino sketch. The Dallas video uses approximately the same instructions that came with the kit, just a little more difficult to follow because it's a video. Don't give up. It took me two weeks to get it the way I wanted. Again, this kit is a good deal, it just requires some research to build. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fun to assemble and full of useful little parts *by J***M on December 8, 2017* I'm giving this 5 stars for the price and because my kit actually did come with pre-soldered motors, as well as a mini-CD with sample code and a video showing how to assemble the kit.

The kit doesn't come with any instructions or code so if you are looking for a step by step, Instructable style, kit this is not the kit you should be buying. This kit is a bunch of independent pieces put together into one package then sold as a "kit" and as a result unless you drill additional holes in the robot chase you are not going to get all the screw holes in the PCBs to align with chase holes. In all this is a fun few hours of layout, assembly, piecing together, and coding. ## Frequently Bought Together - VKmaker Smart Robot Car Chassis Kit with UNO R3 Module - Educational DIY Toy, 2WD with Battery Box and Speed Encoder for Tracking Obstacle Avoidance - Designed for Beginners to Learn Programming - Miuzei Starter Kit Compatible with Arduino Projects, Circuit BreadBorad, LCD1602 Module, Breadboard, Jumper Wires, Servo, Sensors, LEDs, Detailed Tutorial MA05 - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ae/products/35870737-smart-robot-car-chassis-kit-with-uno-r3-module-educational](https://www.desertcart.ae/products/35870737-smart-robot-car-chassis-kit-with-uno-r3-module-educational) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-06-01*
