Virtual Robot with Labview

I have asked the programming teams to create a virtual robot. The robot in the shape of a car was supposed to move inside a virutal room with virtual walls. It was decided to divide the group for four teams, each will develop a subvi and then they will be connected in a main program.
a) Sensors team;
Input:will receive the position of the robot (x,y,alfa)
Output:distance to wall
b) Control team
Input: distance to wall
Output: direction change (angle -100..100), forward motion (0..100%)
c) Movement team
Input : Robot Position, desired change in direction
Output : new robot position (x,y, alfa)
d) drawit team
input : robot position
output: output on screen

Suspension thoughts

Tank drive robots won all the recent years, it is simple and therefore reliable
3 wheels create a surface, therefore a suspension will be needed to keep the wheels on the ground
