1、小车的规格要求:小车长、宽、高不超过25厘米,最多用4节五号电池,电机规格不限,小车出发后不能光控、遥控它。 2、要求:如图1,小车在地面上行驶2.5米后爬上16个台阶;如都能爬上,看谁的小车快。 3、小车制作思路:小车要爬上台阶,必须做成履带式或大轮式。经同学们研究,拟用大轮制作更容易些。考虑到台阶高5厘米,轮子直径要大于10厘米才好爬。轮子要前、后轮同步驱动。
1, the car’s specification requirements: car length, width, height does not exceed 25 cm, up to 4 AA batteries, motor specifications are not limited, the car can not light control, remote control it. 2. Requirements: As shown in Figure 1, the trolley will climb 16 steps after traveling 2.5 meters on the ground; if it can climb, see who’s car is fast. 3, car production ideas: the car to climb the steps must be made track-type or big wheel. After the students studied, it was easier to make a big round. Considering that the step height is 5 cm, the wheel diameter must be greater than 10 cm to climb. The wheels are driven synchronously at the front and rear wheels.
