MathCS - Robotics
Challenge: Travel and Rotate
In this two-part challenge you need to:- travel a distance of D along a straight line, where 50cm <
D < 100cm
Moving along a straight line by D cm - rotate by R degrees, where 90 < R < 360
Rotating by R = 225 degree
Your programming environment can be either NXT-G, LeJOS, or MS Robotics Studio, but NXT-G is recommended for this assignment.
Scoring:
You have one try for each challenge. You need to complete the challenges in two parts, with 10 minute preparation time for each part.
- Each part is worth 50 points
- For the distance part you need to be within 95% of D, otherwise 5 points will be deducted for each additional discrepancy of 5%, i.e. if the distance D is 80cm, you get 50 points if you travel between 76 cm and 84 cm, 45 points for travel between 72 cm and 88 cm, etc.
- For the rotation part you need to be within 10 degrees of the specified rotation, otherwise 5 points will be deducted for each discrepancy of 10 degrees, i.e. if R = 225, you get 50 points for rotation between 215 and 235 degrees, 45 points for rotation between 205 and 245 points, etc.
The team with distance closest to D receives 5 bonus points, the team with the closest rotation receives an additional 5 bonus points.
Results from 9/18/2008:
