Build a Robot which can perform following tasks:
1) Move forward 24"
2) Move foward 12", stop, move backward 12" (come back to same place)
7 kids divided in two teams, working on two different NXT kits
How did we do it?
1) Design/ do the Math: How to move a robot (wheel) 24" (inches) in forward direction ?
Step # 1: Find circumference of wheel by
Step # 2: Find out how many times wheel needs to be roated to travel 24" by using the formula: Number of Rotation = Distance / circumference
It was a good test of math skill for 6th graders and younger kids learned what is circumference and how to measure it.

2) Build:
- Shivan, Chaitanya,
- Avi, Om, Sriya
3) Program:
Rishi, Sankshay, Om, Sriya
4) Test, brainstorm and modify software to meet ground condition
5) Share
Sankshay and Rishi presented their program, explained to whole team steps they followed to build program.
Learning:
1) Both team had issues of moving robot straight forward because of floating front wheel, they both were able to fix the issue by making front wheel stationary.
2) Distance traveled by Robot depends upon size of wheel, surface / friction etc.
