Hi,

Can you check that you do not have any local function or variable with the name robotics defined.

Try

clear

Then again try.

map = robotics.OccupancyGrid(25,25,20)

The Robotics Toolbox has binaryOccupancyMap https://www.mathworks.com/help/robotics/ref/binaryoccupancymap.html

However, OccupancyMap and OccupancyMap3D are from the Navigation Toolbox

Thank you so much Walter. Yes I didn't notice that navigation toolbox is missing. Problem solved.
