Some fascinating developments this year mean motion planners are a trending topic!<\/strong><\/p>\n\n\n\n<!--more-->\n\n\n\n<p>Motion planning is not a new topic\u2026 not by a long mile. Since the very <a name=\"https:\/\/www.wired.com\/story\/wired-guide-to-robots\/\" rel=\"noopener noreferrer\" target=\"_blank\"><\/a><a href=\"https:\/\/www.wired.com\/story\/wired-guide-to-robots\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\" (opens in a new tab)\">beginning of modern robotics<\/a> (in around the 1960s), researchers and engineers have been looking for ways to improve the trajectory planning of their robots.<\/p>\n\n\n\n<p>A lot of progress has been made. Slowly and surely the algorithms have improved. Robots have gradually become able to automatically plan their own routes without bumping into things.<\/p>\n\n\n\n<p>But, recently there has been a flurry of activity in motion planning technologies. Specifically, there are several new technologies which help to achieve real-time motion planning. Unlike with previous software advancements, these new planners use dedicated hardware specifically designed for motion planning.<\/p>\n\n\n\n<p>We&#8217;ve been thinking a lot about motion planning recently because we added a motion planner to the latest version of RoboDK. However, these new hardware technologies approach the problem from a whole new perspective.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why Is Hardware Motion Planning Needed?<\/h2>\n\n\n\n<p>The traditional problem with motion planners is that they are quite slow\u2026 in some cases very slow. This is absolutely fine if you are planning your robot&#8217;s movements in advance (as is the case when you&#8217;re using the one in RoboDK) but it is not very good if you want your robot to react in real-time.<\/p>\n\n\n\n<p>There is a growing need for motion planners which can react and change their plans &#8220;in the moment.&#8221; Robots like Atlas from Boston Dynamics are finally overcoming some of the big physical challenges that have held-back robots for years \u2014 <a name=\"https:\/\/www.nbcnews.com\/mach\/science\/watch-boston-dynamics-atlas-robot-do-parkour-try-not-squirm-ncna919686\" class=\"mce-item-anchor\" target=\"_blank\" rel=\"noopener noreferrer\"><\/a><a rel=\"noopener noreferrer\" href=\"https:\/\/www.nbcnews.com\/mach\/science\/watch-boston-dynamics-atlas-robot-do-parkour-try-not-squirm-ncna919686\" target=\"_blank\">robots can now run, jump, and backflip with ease<\/a>. But, these physical advancements are basically useless if the robot has to stop and wait for 30 minutes every time it needs to re-plan its route.<\/p>\n\n\n\n<p>Even though motion planning algorithms have improved hugely in the past decade, it is still almost impossible to plan routes in real-time using the robot&#8217;s on-board computer.<\/p>\n\n\n\n<p>That&#8217;s where these new hardware motion planners come in. Over the last couple of years, researchers have been working to find ways to offload the computation-heavy parts of motion planning to dedicated hardware.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">4 Trending Motion Planning Technologies<\/h2>\n\n\n\n<p>Here are four of the new hardware-based motion planners which are being developed for robots right now:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Rapid Plan<\/h3>\n\n\n\n<p>Realtime Robotics was listed as one of the &#8220;<a target=\"_blank\" name=\"https:\/\/www.therobotreport.com\/robotics-startups-watch-2019\/\" rel=\"noopener noreferrer\"><\/a><a href=\"https:\/\/www.therobotreport.com\/robotics-startups-watch-2019\/\" target=\"_blank\" rel=\"noopener noreferrer\">10 robotics startups to watch in 2019<\/a>&#8221; in The Robot Report at the start of this year. They recently received $2M in seed funding.<\/p>\n\n\n\n<p>The company&#8217;s product &#8220;RapidPlan&#8221; is a processor specifically designed for motion planning for robotics and autonomous vehicles. <a name=\"https:\/\/spectrum.ieee.org\/automaton\/robotics\/robotics-software\/enabling-faster-more-capable-robots-with-real-time-motion-planning\" class=\"mce-item-anchor\" target=\"_blank\" rel=\"noopener noreferrer\"><\/a><a href=\"https:\/\/spectrum.ieee.org\/enabling-faster-more-capable-robots-with-real-time-motion-planning\" target=\"_blank\" rel=\"noreferrer noopener\">According to the team<\/a>, the processor can solve motion planning in under a millisecond for roadmaps of under 3000 edges. This is a great start, but the team says they need to increase this number before the processor is suitable for guiding autonomous vehicles in real-time.<\/p>\n\n\n\n<p>Not sure what &#8220;roadmaps&#8221; are? <a href=\"https:\/\/robodk.com\/blog\/robot-motion-planning-made-easy\/\" target=\"_blank\" rel=\"noreferrer noopener\">Check out our previous article for an introduction to motion planning.<\/a><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Search-and-Rescue SoC<\/h3>\n\n\n\n<p>Intel&#8217;s The Search-and-Rescue SoC (System-on-a-Chip) is one of <a name=\"https:\/\/spectrum.ieee.org\/automaton\/semiconductors\/processors\/3-new-chips-to-help-robots-find-their-way-around\" class=\"mce-item-anchor\" target=\"_blank\" rel=\"noopener noreferrer\"><\/a><a href=\"https:\/\/spectrum.ieee.org\/automaton\/semiconductors\/processors\/3-new-chips-to-help-robots-find-their-way-around\" target=\"_blank\" rel=\"noopener noreferrer\">three hardware motion<\/a><a href=\"https:\/\/spectrum.ieee.org\/3-new-chips-to-help-robots-find-their-way-around\" target=\"_blank\" rel=\"noreferrer noopener\"> <\/a><a href=\"https:\/\/spectrum.ieee.org\/automaton\/semiconductors\/processors\/3-new-chips-to-help-robots-find-their-way-around\" target=\"_blank\" rel=\"noopener noreferrer\">planners<\/a> which were announced at International Solid-State Circuits Conference (ISSCC) in February 2019.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/robodk.com\/blog\/wp-content\/uploads\/2019\/05\/SoC_Motion_Planner-1024x576.jpg\" alt=\"\" class=\"wp-image-1881\" srcset=\"https:\/\/robodk.com\/blog\/wp-content\/uploads\/2019\/05\/SoC_Motion_Planner-1024x576.jpg 1024w, https:\/\/robodk.com\/blog\/wp-content\/uploads\/2019\/05\/SoC_Motion_Planner-300x169.jpg 300w, https:\/\/robodk.com\/blog\/wp-content\/uploads\/2019\/05\/SoC_Motion_Planner-768x432.jpg 768w, https:\/\/robodk.com\/blog\/wp-content\/uploads\/2019\/05\/SoC_Motion_Planner.jpg 1920w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>The chip is targeted at small mobile robots with limited size and power resources. Its motion planning is achieved by a dedicated accelerator. On top of this, <a name=\"https:\/\/newsroom.intel.com\/news\/intel-shows-collaborative-mini-bots-5g-innovations-brain-inspired-computers-isscc-2019\/#gs.2yio7f\" target=\"_blank\" rel=\"noopener noreferrer\"><\/a>the chip includes all the computing capabilities needed to control a small robot, including real-time sensing and processing, power management, actuation, and communication.<\/p>\n\n\n\n<p>Although it&#8217;s currently limited to mobile robots, the team at Intel is hoping to extend the chip&#8217;s capabilities to work for drones.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Wave Computer<\/h3>\n\n\n\n<p>The second chip announced at ISSCC 2019 is being developed by a team at the University of Minnesota. Unlike the previous two examples, their hardware is not limited to motion planning. It can be used for even more applications.<\/p>\n\n\n\n<p>The Wave Computer is a solid-state chip dedicated to running the A* algorithm.<\/p>\n\n\n\n<p><a target=\"_blank\" name=\"https:\/\/en.wikipedia.org\/wiki\/A*_search_algorithm\" rel=\"noopener noreferrer\"><\/a><a href=\"https:\/\/en.wikipedia.org\/wiki\/A*_search_algorithm\" target=\"_blank\" rel=\"noopener noreferrer\">The A* search algorithm<\/a> is one of the classic algorithms and is widely used in pathfinding applications. It can achieve high-performance and accuracy, but it can be energy intensive. The team says that their chip is about 1 million times more energy efficient than using the same algorithm on computer and graphics processors.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. The SLAMmer<\/h3>\n\n\n\n<p>The final chip announced at ISSCC 2019 was the SLAMmer from researchers at the University of Michigan.<\/p>\n\n\n\n<p>As the name suggests, it uses Simultaneous Localization and Mapping (SLAM). It is a purpose-built chip which can achieve SLAM with 97.9% accuracy when used in a moving vehicle.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/robodk.com\/blog\/wp-content\/uploads\/2019\/05\/SLAM_Car-1024x576.jpg\" alt=\"\" class=\"wp-image-1887\" srcset=\"https:\/\/robodk.com\/blog\/wp-content\/uploads\/2019\/05\/SLAM_Car-1024x576.jpg 1024w, https:\/\/robodk.com\/blog\/wp-content\/uploads\/2019\/05\/SLAM_Car-300x169.jpg 300w, https:\/\/robodk.com\/blog\/wp-content\/uploads\/2019\/05\/SLAM_Car-768x432.jpg 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p><a name=\"https:\/\/en.wikipedia.org\/wiki\/Simultaneous_localization_and_mapping\" rel=\"noopener noreferrer\" class=\"mce-item-anchor\" target=\"_blank\"><\/a><a rel=\"noopener noreferrer\" href=\"https:\/\/en.wikipedia.org\/wiki\/Simultaneous_localization_and_mapping\" target=\"_blank\">SLAM<\/a> \u2014 if you haven&#8217;t heard of it \u2014 is a very tough computational problem in robotics which involves trying to map an unknown environment using only the data from the robot&#8217;s sensors. The algorithm builds the map on-the-fly whilst also locating where the robot is within that map. <\/p>\n\n\n\n<p>SLAMmer isn&#8217;t specifically a motion-planning chip. However, without a good map a motion planner can&#8217;t do anything.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The Future of Real-Time Motion Planning<\/h2>\n\n\n\n<p>Currently, the heavy computation required for motion planning is usually uploaded &#8220;to the cloud.&#8221; This approach can sometimes achieve real-time performance, but only if your robot has a flawless internet connection and it doesn&#8217;t require sending too much data. However, this is not a viable solution in the long term.<\/p>\n\n\n\n<p>Hardware motion planners could certainly be the answer. For applications where real-time motion planning is critical \u2014 such as with autonomous vehicles \u2014 this type of purpose-built hardware is a great option.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to Try Motion Planning for Yourself<\/h2>\n\n\n\n<p>In industrial robotics, we don&#8217;t need real-time motion planning. In fact, generating plans on-the-fly could actually be dangerous in an industrial environment.<\/p>\n\n\n\n<p>What we do need is a motion planner which helps us when we are planning our robot applications. And that&#8217;s exactly what we&#8217;ve included in the latest version of RoboDK.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"578\" src=\"https:\/\/robodk.com\/blog\/wp-content\/uploads\/2019\/05\/Auto_Generated_Motion_Plan-1024x578.jpg\" alt=\"\" class=\"wp-image-1886\" srcset=\"https:\/\/robodk.com\/blog\/wp-content\/uploads\/2019\/05\/Auto_Generated_Motion_Plan-1024x578.jpg 1024w, https:\/\/robodk.com\/blog\/wp-content\/uploads\/2019\/05\/Auto_Generated_Motion_Plan-300x169.jpg 300w, https:\/\/robodk.com\/blog\/wp-content\/uploads\/2019\/05\/Auto_Generated_Motion_Plan-768x433.jpg 768w, https:\/\/robodk.com\/blog\/wp-content\/uploads\/2019\/05\/Auto_Generated_Motion_Plan.jpg 1055w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>You can now try out our new motion planner for yourself!<\/p>\n\n\n\n<p>Check out the <a href=\"https:\/\/robodk.com\/doc\/en\/Collision-Avoidance.html\">documentation<\/a> for details on how to get started.<\/p>\n\n\n\n<p><em>What applications can you think of that would benefit from real-time motion planning? <strong>Tell us in the comments below or join the discussion on <\/strong><\/em><a rel=\"noopener noreferrer\" href=\"https:\/\/www.linkedin.com\/company\/robodk\/\" target=\"_blank\"><em><strong>LinkedIn<\/strong><\/em><\/a><em><strong>, <\/strong><\/em><a rel=\"noopener noreferrer\" href=\"https:\/\/twitter.com\/robodkinc\" target=\"_blank\"><em><strong>Twitter<\/strong><\/em><\/a><em><strong>, <\/strong><\/em><a rel=\"noopener noreferrer\" href=\"https:\/\/www.facebook.com\/robodkinc\" target=\"_blank\"><em><strong>Facebook,<\/strong><\/em><\/a><em><strong> <\/strong><\/em><a rel=\"noopener noreferrer\" href=\"https:\/\/www.instagram.com\/robodkinc\/\" target=\"_blank\"><em><strong>Instagram<\/strong><\/em><\/a><em><strong> or in <\/strong><\/em><a rel=\"noopener noreferrer\" href=\"https:\/\/robodk.com\/forum\/\" target=\"_blank\"><em><strong>the RoboDK Forum<\/strong><\/em><\/a><em><strong>.<\/strong><\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>We&#8217;re not the only ones who have been talking about robot motion planning recently.
