DoF refers to the specific number of axes that a rigid body is able to freely move in 3D space. A 6DoF robot arm can reach any given point in space, with any given orientation.<\/p>\n\n\n\n<p><strong> A 6DoF robot arm can perform a wide variety of tasks: <\/strong><\/p>\n\n\n\n<ul>\n<li>Grasp a tool at the far end of the handle, flip it and put it back<\/li>\n\n\n\n<li>Open a drawer, grasp an item and close the drawer<\/li>\n\n\n\n<li>Write down on a desk or on a wall<\/li>\n<\/ul>\n\n\n\n<p>A 7DoF robot arm is the most similar to a human arm. It replicates the human arm motion the best. will replicate human movements Un bras robotique dot\u00e9 de 7 degr\u00e9s de libert\u00e9 (DoF) est celui qui se rapproche le plus du bras humain. More agile and faster than a 6DoF robot arm, it can reach inaccessible spots that a 6DoF robot arm can\u2019t.<\/p>\n\n\n\n<h2 id=\"h-strength-and-reach\">Strength and reach<\/h2>\n\n\n\n<p>The strength (maximum payload) and the maximum reach are the next two criteria that will require your attention. <br \/>Think about the project you will be working with your robot arm. Will the robot have to carry heavy items or apply a force to a mechanism? Be aware that a robot with a higher maximum payload will lose in accuracy. <br \/>The robot reach is the distance from the center of the robot to the fullest extension of the robotic arm.<\/p>\n\n\n\n<h2 id=\"h-speed-and-accuracy\">Speed and accuracy<\/h2>\n\n\n\n<p>Accuracy is an important consideration if the robot arm have to interact with small parts or tiny items. <br \/>A robot repeatability (how well the robot can reproduce the same move in unchanged conditions) will be an important criteria during a pick and place task in a laboratory. If the robot is used in an experiment about home care, a high maximum speed will probably not be a major consideration.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter\"><a href=\"https:\/\/blog.generationrobots.com\/wp-content\/uploads\/2019\/10\/panda-franka-emika-care-robot-arm-1.jpg\"> <img decoding=\"async\" width=\"800\" height=\"533\" class=\"wp-image-6218\" src=\"https:\/\/blog.generationrobots.com\/wp-content\/uploads\/2019\/10\/panda-franka-emika-care-robot-arm-1.jpg\" alt=\"Franka Emika Panda robot used as a care robot\" srcset=\"https:\/\/www.generationrobots.com\/blog\/wp-content\/uploads\/2019\/10\/panda-franka-emika-care-robot-arm-1.jpg 800w, https:\/\/www.generationrobots.com\/blog\/wp-content\/uploads\/2019\/10\/panda-franka-emika-care-robot-arm-1-300x200.jpg 300w, https:\/\/www.generationrobots.com\/blog\/wp-content\/uploads\/2019\/10\/panda-franka-emika-care-robot-arm-1-768x512.jpg 768w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/> <\/a><\/figure>\n\n\n\n<h2 id=\"h-other-decision-making-criteria-in-the-purchase-of-a-robot-arm\">Other decision-making criteria in the purchase of a robot arm<\/h2>\n\n\n\n<p>We added to our \u00ab\u00a0checklist\u00a0\u00bb five other decision-making criterias:<\/p>\n\n\n\n<ul>\n<li>Number of grippers available for the robot<\/li>\n\n\n\n<li>ROS compatibility<\/li>\n\n\n\n<li>Is it a collaborative robot?
