While it's a fantastic learning project, successful assembly requires the ability to read circuit diagrams and handle a soldering iron. Beginners are encouraged to review the instructions thoroughly and practice basic soldering before starting.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What batteries does the ultrasonic obstacle avoidance robot car use?\u003c\/h4\u003e\n\u003cp\u003eA: The robot car requires 4 × AA batteries (DC 6V total) to operate. Please note that batteries are NOT included in the kit and must be purchased separately.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I adjust how close the car gets to an obstacle before it turns away?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! The obstacle avoidance distance is fully adjustable. Long-press the SW1 button to enter settings mode, then use the \"+\" or \"−\" buttons to set your desired distance (between 0 and 2.55 meters). The default setting is 0–0.2 meters. Setting the value to 0 disables the obstacle avoidance function entirely.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the maximum detection range of the ultrasonic sensor?\u003c\/h4\u003e\n\u003cp\u003eA: The ultrasonic sensor can detect obstacles at distances of up to 5 meters, with the current distance displayed in real time on the onboard digital tube display.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Is this DIY robot car kit suitable for beginners?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This kit is best suited for individuals who already have some experience with electronics and soldering.
