Walker Controller


Advanced

1 hour

Grades 6 - 8

MISSION OBJECTIVE

Build a controller to steer your Walker using buttons—code it to follow your commands in real time!

Walker’s steps feel a little off, so we work with Pip and Piperbot to smooth out the movement. With the right code, we help Walker stride with confidence across the Martian surface.

MISSION RESOURCES

Learning Goals

  1. Students will program smooth, continuous walking for Walker using mathematical functions.
  2. Students will apply sine wave calculations, phase shifting, and steering offsets to control leg movement in real-time, integrating both math and controller input to simulate natural robotic gait.
I WILL BE ABLE TO...
  • Use sine waves and math functions to create smooth back-and-forth movement for Walker’s legs
  • Adjust phase to change how Walker’s legs move together or apart
  • Use offset values to make Walker steer left or right
  • Control Walker in real-time using my controller to adjust movement while it’s walking
