What is Acceleration?<\/h2>\n

Acceleration refers to how quickly your rover can get up to speed and slow down. You can add the following code to your PhidgetsRover<\/i> project, or create a new project. If you\u2019ve forgotten how to do this, revisit the Configure section<\/a> from the Getting Started Kit. <\/pee>[\/et_pb_code][\/et_pb_column_inner][\/et_pb_row_inner][et_pb_row_inner admin_label=”Row” _builder_version=”4.4.1″ box_shadow_horizontal_tablet=”0px” box_shadow_vertical_tablet=”0px” box_shadow_blur_tablet=”40px” box_shadow_spread_tablet=”0px” module_id=”write-code” module_class=”ph-user-java” vertical_offset_tablet=”0″ horizontal_offset_tablet=”0″ z_index_tablet=”0″][et_pb_column_inner type=”4_4″ saved_specialty_column_type=”2_3″ custom_padding__hover=”|||” custom_padding=”|||” saved_specialty_column_type=”2_3″][et_pb_code admin_label=”Write code Java” _builder_version=”4.6.6″ box_shadow_horizontal_tablet=”0px” box_shadow_vertical_tablet=”0px” box_shadow_blur_tablet=”40px” box_shadow_spread_tablet=”0px” vertical_offset_tablet=”0″ horizontal_offset_tablet=”0″ z_index_tablet=”0″ saved_tabs=”all”]<\/p>\n

Code review<\/h2>\n
Looking at the code above, this is what you would expect to happen.<\/p>\n
    \n
  1. Move forward at full speed for one second.<\/li>\n
  2. Move backward at full speed for one second.<\/li>\n
  3. Stop moving.<\/li>\n<\/ol>\n
    Because of this, you would expect that the rover ends up in approximately the same position it started at. The reason it does not is because of the acceleration property<\/strong>. Essentially, the default acceleration is too low! Move on to the next step to learn how to fix this.<\/p>\n

    1. Your rover should drive in the direction that the Sonar Phidget is facing. If it isn’t, simply use negative values for your Target Velocity. This will make the motors spin the opposite direction!<\/li>\n
    2. Make sure everything is plugged in properly and your VINT Hub is connected to your computer.<\/li>\n
    3. Stop running other programs that are using your Phidgets before running a program.<\/li>\n<\/ol>\n
