Introduction to Robotics - Ping! how far is the obstacle?


The Cartesian coordinate system, invented by the 17th century mathematician, Rene Descartes, showed a way to connect Geometry and Algebra. This lesson will take you on a journey into Descartes’ world and teach you to understand this world, navigate it, and master it with MathBot.

Learning Outcomes

Students will:

  • Learn to locate points and specify locations in the cartesian plane
  • Navigate, plan, and reflect upon trajectories of a robot in a static environment
  • Learn about powers of 10
  • Learn about geometric shapes

Mathematics Florida Standards (MAFS) Grade 5

MAFS.F.OA.1.1; MAFS.F.OA.1.2; MAFS.F.MD.1.1; MAFS.F.G.1.1; MAFS.F.G.1.2; MAFS.F.G.2.3; MAFS.F.G.2.4;


Teacher Setup:
  • Set up a coordinated grid using the masking tape.
  • Add 4 locations (starting point, church, mall and school) according to the following schematic; however, do not write down the location/coordinate because the students will be responsible for providing with the correct points:
  • Place the MathBot at the starting point.
Student Teams' Robotic Tasks (Robot Dependent):
  • Provide a written trajectory for the MathBot to go to the school following the correct coordinates. (Example: to arrive the mall, the MathBot needs to move the following trajectory: (1,0)->(1,2)->(1,3)
  • Program the robot to park in front of the school on the correct square point. Remember to avoid hitting any obstacle.
  • What is the distance of the trajectory selected in the previous questions?
  • Program the robot to return to the starting point avoiding any coordinate already visited.
  • What is the distance of the trajectory designed in the previous questions?
