The instructors also need to make sure the students always use the required personal protective equipment when drilling holes for mounting the equipment.<\/p><p>The first task for the students is to familiarize themselves with the robot. Since they should have taken the online training beforehand it should be quite straightforward to get the robot to move around.<\/p><p><span style=\"text-align: var(--text-align)\">When they have the robot running, the students divide themselves between the various practical tasks of wiring power to the cabinet, mounting the sensors to the metal frame and running signal wire according to the schematic. These tasks are intentionally pre-planned and practical so that they can be started on at once and in parallel.<\/span><\/p><p><span style=\"text-align: var(--text-align)\">When the equipment is installed and properly labeled the students can experiment with the different ways the robot can be made to react when the safety curtain is being triggered. The need to decide if it should slow down, pause, stop, or just avoid certain areas. Their decision and motivation are logged and become part of their risk-analysis documentation.<\/span><\/p><p><span style=\"text-align: var(--text-align)\">Depending on team decisions, two teams that share the same robot may end up deciding that they both need to use the same safety input. If this happens, they need to connect their light curtains in series. This is covered in the Wednesday lecture <\/span><em style=\"text-align: var(--text-align)\">3.7 Talking in the workshop: Combining safety systems and <\/em><u style=\"text-align: var(--text-align)\">3.7 topography_light_curtain.pdf<strong> (HYPERLINK). (<\/strong><\/u><span style=\"text-align: var(--text-align)\">If each team has access to a robot each, this contingency will not be needed.)<\/span><\/p><p>After they have completed their safety improvements and documentation there is secondary task available to the teams. Using any remaining time, they should attempt to improve to the efficiency of the robot program using the capacitive sensor in the gripper. Note that this is NOT an approved safety sensor and should not be relied on to increase the safety of the installation.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-7bccef9 e-flex e-con-boxed e-con e-parent\" data-id=\"7bccef9\" data-element_type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-b09e45a elementor-widget elementor-widget-heading\" data-id=\"b09e45a\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Program for MicroChallenge 3<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-f4c87b0 e-flex e-con-boxed e-con e-parent\" data-id=\"f4c87b0\" data-element_type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-f821559 elementor-widget elementor-widget-image\" data-id=\"f821559\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<style>\/*! elementor - v3.21.0 - 22-05-2024 *\/\n.elementor-widget-image{text-align:center}.elementor-widget-image a{display:inline-block}.elementor-widget-image a img[src$=\".svg\"]{width:48px}.elementor-widget-image img{vertical-align:middle;display:inline-block}<\/style>\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"678\" height=\"603\" src=\"https:\/\/robocup.website\/wp-content\/uploads\/2023\/09\/MC3-program.jpg\" class=\"attachment-large size-large wp-image-953\" alt=\"\" srcset=\"https:\/\/robocup.website\/wp-content\/uploads\/2023\/09\/MC3-program.jpg 678w, https:\/\/robocup.website\/wp-content\/uploads\/2023\/09\/MC3-program-300x267.jpg 300w\" sizes=\"(max-width: 678px) 100vw, 678px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-570d9c6 e-flex e-con-boxed e-con e-parent\" data-id=\"570d9c6\" data-element_type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-d5ee2a3 elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"d5ee2a3\" data-element_type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"elementor-divider\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-3e50dae e-flex e-con-boxed e-con e-parent\" data-id=\"3e50dae\" data-element_type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-77a4db4 elementor-widget elementor-widget-text-editor\" data-id=\"77a4db4\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<h2 class=\"wp-block-heading\">Resources\/ Presentations<\/h2><table width=\"887\"><tbody><tr><td width=\"73\"><strong>No<\/strong><\/td><td width=\"264\"><strong>Activity<\/strong><\/td><td width=\"550\"><strong>Resources<\/strong><\/td><\/tr><tr><td width=\"73\">\u00a0<\/td><td width=\"264\">3D Files for all parts<\/td><td width=\"550\"><a href=\"http:\/\/robocup.website\/wp-content\/uploads\/2024\/05\/3D_models.zip\" target=\"_blank\" rel=\"noopener\">Download 3D_models.zip<\/a><br \/>or <br \/><a href=\"https:\/\/github.com\/robotikklinja\/robocup\" target=\"_blank\" rel=\"noopener\">Link to github repository<\/a><\/td><\/tr><tr><td width=\"73\">3.1<\/td><td width=\"264\">Presenting the case<\/td><td width=\"550\"><a href=\"http:\/\/robocup.website\/wp-content\/uploads\/2024\/05\/3.1-The-Case-3.pptx\">3.1 The case.pptx, PowerPoint presentation<\/a><br \/><a href=\"http:\/\/robocup.website\/wp-content\/uploads\/2023\/09\/3.1-The-Case-3.pdf\" target=\"_blank\" rel=\"noopener\">3.1 Presentation &#8211;
