The Motion Planning Game can be used to test skill.

The games are Moving Objects,  Robot Arm, Driving a Car and Multiple Robots. 

If you choose the Robot Arm games there are six challenges to complete.

 

 

The three Movements L1, L2 and L3 correspond to the shoulder, elbow and wrist of the arm.

The idea of the game is to achieve your goal in the least number of movements.

It is very easy for a person to “forget” how they did it when the goal is achieved so…

Record your Mouse Clicks in this PROGRAM FORMAT

 

01        L1        RIGHT ONE

02        L2        LEFT              TWO

03

04

 

Once you have completed your program and recorded it you may wish to revise what you have done.

This task is now repeatable as you only have to follow the program.

 

The problems that would occur in a “real life” situation would be the exact positioning of the arm and the goal to be achieved.

This is a reason “feedback’ is important so that a check on progress can be made.

 

We could change our code into a “machine code” by following these rules.

 

Let us assume that

1.                  There would be a maximum number of commands. This could be 64 ( 6 bits needed) (11 1111₂=65₁₀)

2.                  L1 is represented by the bit 0 and L2 is represented by the bit 1

3.                  RIGHT is represented by the bit 0 and LEFT by the bit 1

4.                  The number of CLICKS is represented by 7 bits ( 111 1111₂=127₁₀)

 

Our first and second lines of code would be

000000 0 0 0000001

000001 1 1 0000010

 

Our program would also have to start with the arm in the original rest position. We would need to have a special line of code to return the arm to the rest position.
