Teammates: Christine & Vicky
Our car is controlled by Micro Bits. We set codes to make the car keep moving forward and backward to measure the error. During the process, we found many factors that actually may increase the errors. For example, the m2 port for motors seemed to have some problems and the wheels were too close to the screws so the car was actually turning. In addition, in order to make the trace easier to measure, we set the speed to the highest and extended the duration time.
The measuring object is the car’s back location when the car moves forward and backward. Rudi suggested that it is better to set a coordinate axis for all the signs I marked on the ground. Below are the statistics.
| Location | Variables | |
| Original Point | (0, 0) | |
| Point 1 | (-11, -6.7) | X: -11, Y: -6.7 ↙ |
| Point 2 | (17, -0.5) | X: +28, Y: +6.2 ↗ |
| Point 3 | (47.6, 1.7) | X: +30.6, Y: +2.2 ↗ |
| Point 4 | (62.4, 0.8) | X: +14.8, Y: -0.9 ↘ |
It is obvious to see that the error is quite large. Not only the distance but also the direction would change even though the program is the same.
