STOOOOOOOOP!

What? It doesn’t always work as you expect?

How do you usually solve a new challenge?

Build a Rhino!

student-02

This build has two parts:

  • Rhino's Body

  • Rhino's Head

Make it Move

SPIKE Extra resources Going Distance Step03-Program - en-us
student-03

Place a LEGO brick 1 meter (39 in.) from the Rhino's nose.

Play the program and see what happens.

The Rhino should run over the LEGO brick, showing no mercy!

Stop at the brick!

student-04

Keeping the LEGO brick 1 meter (39 in.) from the Rhino's nose, adjust your program to make the Rhino stop as close to the brick as possible, without touching it.

How many wheel rotations will move the rhino as close as possible to the brick, without knocking it over?

Calculate how many times the circumference of the wheel fits into the distance to be traveled. Use this calculation to figure out the number of rotations you should enter as the block parameter.

student-04-hint

d = 5.6 cm (or d = 2.2 in.)

Ready for a challenge?

student-05

Place the LEGO brick 120 cm (47 in.) from the Rhino's nose.

You have one chance to program the Rhino to stop as close to the brick as possible, without knocking it over.

Good luck!

Can you make the Rhino stop when its nose hits a ”wall?”

student-06

Create 2 program stacks:

  • One without a sensor
  • One using the Force Sensor (the Rhino’s nose)

Play the program stacks separately and describe how your rhino’s reactions change.

The Force Sensor enables the rhino to detect objects when it touches them, regardless of the starting distance.

This program doesn’t use the Force Sensor:

Think about how you did.

What did you do well? Is there anything you could’ve done better?

Good to know you've solved that challenge!
