About motor parameters:
We choose a reduction ratio of 48:1, the line length is 15cm, and the travel speed is about 0.65M/S under the condition of 7.2V rechargeable battery power supply measured by the code disc. This speed is good (applicable to most smart car applications). Of course, increasing the drive voltage can increase its speed. The motor working voltage is recommended to be between 5-10V.
Car chassis size: about 26cmX15cm
The motor bracket is made of hard aluminum alloy, which is durable and stable
Regarding the material of the car chassis, we use imported acrylic transparent material (it has better toughness and is not so easy to break).
Corresponding holes are opened on the chassis of the car, which is convenient for users to install and use directly, especially users who use the Arduino UNO development board.
