Program Review: Turn in Place 90 degrees
- The program shown below is a sample solution to the 90 degree turn Mini-Challenge.
The robot turns 90 degrees to its right, using a Move Steering Block with steering set to +100 (turn to the right in place).
- Note: This program assumes you are using the default EV3-RE design,
and is only approximate – your robot may require a slightly different number of rotations.
Program Review: Dizzy Drill (Square Turns)
- The program shown below is a sample solution to the Dizzy Drill Mini-Challenge.
This solution uses multiple 90-degree turns to navigate around the obstacle.
Move Steering Block
On for Rotations
Moves the robot forward 5 wheel rotations at 50% power.
Moves past the obstacle.
Move Steering Block
On for Rotations
Makes a point turn to the right, for 0.5 wheel rotations (approx. 90 degrees body turn) at 50% power.
Turns the robot in place, 90 degrees to the right.
Move Steering Block
On for Rotations
Moves the robot forward 2 wheel rotations at 50% power.
Moves forward, traveling behind the obstacle.
Move Steering Block
On for Rotations
Makes a point turn to the right, for 0.5 wheel rotations (approx. 90 degrees body turn) at 50% power.
Turns the robot in place, 90 degrees to the right.
Move Steering Block
On for Rotations
Moves the robot forward 5 wheel rotations at 50% power.
Moves back to the start.
Program Review: Dizzy Drill (Wide Turns)
- The program shown below is a sample solution to the Dizzy Drills Mini-Challenge.
This solution uses a single "wide" U-shaped turn to navigate around the obstacle.
Move Steering Block
On for Rotations
Moves the robot forward 5 wheel rotations at 50% power.
Moves past the obstacle.
Move Tank Block
On for Rotations
Runs left motor at 100% power, and right motor at 50% power, until the faster(left) motor passes 3.8 rotations.
Makes a "wide" turn to the right, forming a semicircle behind and around the obstacle.
Move Steering Block
On for Rotations
Moves the robot forward 5 wheel rotations at 50% power.
Moves back to the start.
