Smart Robot Car Chassis Kit with UNO R3 Module - Educational DIY Toy, 2WD with Battery Box and Speed Encoder for Tracking Obstacle Avoidance -

The VKmaker New Avoidance tracking Motor Smart Robot Car Chassis Kit with Speed Encoder, Battery Box, 2WD Ultrasonic module, and Tutorial CD has received mixed reviews. While some reviewers found that the kit had good instructional documentation and came with pre-soldered wires, others criticized the lack of build instructions and missing parts such as screws and wires. Some reviewers recommended using alternative instructions available online, citing issues with the code that comes with the kit. A customer reported that he had purchased 17 kits for his class, but found that they did not come with build instructions, making it difficult for beginners to work out what goes where. Another buyer had to improvise a replacement wire as one of the wires from the toggle switch was missing. One customer initially bought the kit to work on with his grandson but soon found that the kit required a lot of research to build and was not suitable for beginners. Another buyer was disappointed with the quality of the product, citing broken pieces in the kit and issues with missized holes. However, one reviewer found that the kit was a good deal and had fun building it in the end. Another customer appreciated the fact that the motor and switch wires had already been soldered on in the kit. Overall, the VKmaker New Avoidance tracking Motor Smart Robot Car Chassis Kit has largely received mixed reviews, with some customers praising its affordability, while others found it difficult to assemble and missing important parts.
