Ask HN: Courses/textbook recommendations for studying robotics?
Hi HN,
I am studying robotics and exoskeletons as a hobby. Can HN please recommend high quality resources for self study?
- randcraw 3y agoFor mobile, "Introduction to Autonomous Mobile Robots" by Siegwart et al. For motion, "Principles of Robot Motion: Theory, Algorithms, and Implementations" by Choset, et al. It's telling that few new robotics textbooks have shipped in the past 10-15 years.
- mohsaad 3y agoProbabilistic Robotics by Thurn/Burgard/Fox is basically the best resource for anything SLAM or planning related. Artificial Intelligence: A Modern Approach by Russell/Norvig is another good book for planning and AI.
- jfrd 3y agoAre any subtopics particularly interesting to you? Mechatronics, Computer Vision, Control Theory, State Estimation, Path Planning, etc?
- auxym 3y agoSecond that. Similar questions get posted pretty often in engineering subreddits and it's difficult to answer as robotics is so multi-disciplinary. Very few people in this world are skilled enough in embedded programming, PCB design (motor control and sensors), materials and structures, dynamics and kinematics, controls and machine design (CAD, selecting manufacturing processes, selecting various COTS mechanical parts like actuators and bearings) to be a one-man-robot making orchestra. Advice to OP: pick a specialization to start with, and focus on learning that while using pre-made parts for the rest. For example, buy a ready-made robotic arm and write path planning and controls software to operate it. Or build your own CNC router/pick-and-place/3D printer/pen plotter but use off the shelf/open-source electronics and firmware. Once that's done, pick another specialty and move on to that if it interests you.
- antiviral 3y agoGood advice. Can you recommend the names of any off-the-shelf robotic arms or tools that can be modified or hacked? Any good standard starting points for controller software?
- jonathankoren 3y agoThere's plenty of toy arms for programming on every electronics site, including amazon. They're basically just a series of exposed hobby servos mounted together in a plastic skeleton. The motors are pretty much standard. You can even buy them with or without an control board. Buy an Arduino Mega or something. That way you'll have way more pins that you'll need, and shouldn't hit up against the memory limits. Arduinos have a huge community, and the free IDE has all libraries and everything you need. I bought one and an MP3 shield from AdaFruit last year and successfully made a GNK droid. complete with flashing lights and multiple modes of tranquil gonks.
- tomp 3y agoI recently researched "cheap" (not really but not super extra expensive) robot arms. (Disclaimer: I haven't bought any of them, so can't say anything about the quality.)

- thomasthorpe 3y agoThe Niryo arm is a high quality kit with good software support package if not updated as often as it could be https://www.niryo.com https://www.niryo.com
- GlenTheMachine 3y agoThe classic book for kinematics and dynamics is John Craig, Introduction to Robotics: Mechanics and Control, published by Pearson. Despite the title, it isn't a particularly good controls book. But it's the standard for kinematics.
- techbro92 3y ago“Robotics dynamics algorithms” by Featherstone is a great book to read for modern forward and inverse dynamics and spatial vector algebra.
- ericdfoley 3y agoIf you're interested in perception, like tracking & freespace detection or SLAM, then "Probabilistic Robotics" by Thrun is pretty good. For a more fundamental take on that stuff (but less robotics specific), "Pattern Recognition and Machine Learning" by Bishop is my favorite.
- jaredandrews 3y agoLearn thru experience and consider mentoring a FIRST robotics team in your area.
- petrw 3y agoThe really big shift in ai in a sense was to reject the sense-model- plan- act cycle. I continue to see researchers assuming SMPA so although "everyone" knows this,"Intelligence without representation" by Brooks is essential. The alternative is sense-act in one layer, and model-plan over the top.
- egl2021 3y agoI apparently wasn't paying attention: can you elaborate on what it is that "everyone" knows?
- pgorczak 3y agoNonlinear systems and control could be something that’s useful to get into regarding legged robots or exoskeletons. It’s not covered in depth by many general robotics textbooks but there’s a great lecture including fantastic interactive notebook material at http://underactuated.mit.edu/ http://underactuated.mit.edu/
- jstmm 3y agoKevin Lynch has a great course "Modern Robotics: Mechanics, Planning, and Control Specialization" on coursera. It covers the key ideas in robotics at a high level (however it leaves out perception). I recommend it for people interested in getting started on this topic. https://www.coursera.org/specializations/modernrobotics#courses https://www.coursera.org/specializations/modernrobotics#cour...

- anfractuosity 3y agoI bought a 6DOF robot arm a while ago, which uses servos driven by PWM, which I found quite fun. It was only around £70 for the servos + metal framework. I drive it with a Pi and a PCA9685 based I2C board. I was driving with a 5V supply, but it looks like the servos can run at 6V, which I need to try, as the bottom servo in the arm doesn't seem to have quite enough power. I'd like to sometime try to 'teach' it to draw with a pen (however badly), 'Inverse kinematics' feels rather scary though, so wonder if anyone might have any very basic tutorials on this. Tangentially related, I just bought 'The Ultimate Guide To DIY Animatronics' yesterday, which I'm looking forward to reading when it arrives. And have been watching a few videos on animatronics such as: * https://www.youtube.com/watch?v=y0R8-F4TmPI https://www.youtube.com/watch?v=y0R8-F4TmPI - 'Show and Tell: Animatronic Raven Kit!' * https://www.youtube.com/watch?v=uNIfx0Xddzc https://www.youtube.com/watch?v=uNIfx0Xddzc - 'How Realistic Animatronics Are Made For Movies & TV | Movies Insider' Curious if anyone has any recommendations for videos/books in this area?
- thomasthorpe 3y agoTry the Robot Operating System documentation for the software and control side. If you can write the low level drivers then the ROS stack abstracts the IK and other middleware layers allowing you to focus on app and problem spaces. https://docs.ros.org https://docs.ros.org
- anfractuosity 3y agoThanks, that sounds really interesting, will definitely have to try that out.
- stonemetal12 3y ago>'Inverse kinematics' feels rather scary though, so wonder if anyone might have any very basic tutorials on this. You might look into graphics programming and 3d modeling. For example Blender supports Inverse Kinematics for creating character animation.

- cashsterling 3y agoKevin Lynch's book is free and very good: http://hades.mech.northwestern.edu/index.php/Modern_Robotics http://hades.mech.northwestern.edu/index.php/Modern_Robotics - someone already mentioned his course. The Robotics resources and texts by Peter Corke are good: https://petercorke.com/ https://petercorke.com/ -also has this good related course: https://robotacademy.net.au/ https://robotacademy.net.au/ "Controls Engineering in the FIRST Robotics Competition" by Tyler Veness is free and a good short reference: https://controls-in-frc.link/ https://controls-in-frc.link/ Also add the MIT Robotics Series books: https://mitpress.mit.edu/series/intelligent-robotics-and-autonomous-agents-series/ https://mitpress.mit.edu/series/intelligent-robotics-and-aut... Algorithms for Decision Making is free and awesome: https://algorithmsbook.com/ https://algorithmsbook.com/ Also looks really good (MIT Press hardcopy): https://introduction-to-autonomous-robots.github.io/ https://introduction-to-autonomous-robots.github.io/
- vinte 3y agoThanks, what about resourses for reinforcement learning in robotics.
- cashsterling 3y agoI'd say RL is an advanced robotics topic. There are some books out there that cover introductory or general RL aspects... after that you'll have to dive into papers and specific code bases. Might not be a bad idea to start with a Python-based, practical RL book and move from practical demonstrations towards theory. Although not an RL book, I really like Data-Driven Science and Engineering by Brunton and Kutz: - https://www.databookuw.com/ https://www.databookuw.com/ - https://www.amazon.com/Data-Driven-Science-Engineering-Learning-Dynamical-dp-1009098489/dp/1009098489/ref=dp_ob_title_bk https://www.amazon.com/Data-Driven-Science-Engineering-Learn... Steve Brunton also has an awesome youtube channel on dynamic systems, control, and machine learning. Robotic books with some RL concepts (don't have either of these tbh): - https://introduction-to-autonomous-robots.github.io/ https://introduction-to-autonomous-robots.github.io/ - https://mitpress.mit.edu/9780262046169/learning-for-adaptive-and-reactive-robot-control/ https://mitpress.mit.edu/9780262046169/learning-for-adaptive...

Control Systems and Reinforcement Learning by Sean Meyn looks to be on topic but I haven't read through it.
- huevosabio 3y agoTake a look at Stanford's Principles of Robotic Autonomy: http://asl.stanford.edu/aa274a/ http://asl.stanford.edu/aa274a/
- ForestCritter 3y agoWell, from my experience in a partially automated factory 'wrangling the robots' I would do a little foray into 'things that can go wrong'. Our robot arms would periodically have 'robot revolt parties'. Watched a robot arm reach up and push a compressor right off a ten foot dead nest. It didn't drop it or fumble, it cleanly swept it right off. So many small things could trigger problems and sometimes the fixes were odd, like one robot refused to reset unless you opened and closed a certain one of the cage doors despite having done the proper reset process in the computer.
- antegamisou 3y agoThis reply will focus mainly on the academics. Since you've mentioned exoskeletons, knowledge of kinematics and dynamics is imperative. Rotation Matrices, Forward/Inverse Kinematics, Denavit - Hartenberg Parameters, Lagrangian Mechanics are a few fundamental concepts one should be familiar with. Their applications mostly pertain to robotic manipulators (arms), which are what members of exoskeleton's are modeled after. They're covered extensively in the classic in the field textbook Robotics Modelling, Planning and Control by Siciliano, Sciavicco, Villani, Oriolo https://link.springer.com/book/10.1007/978-1-84628-642-1 https://link.springer.com/book/10.1007/978-1-84628-642-1 They also require some prior knowledge of linear algebra to safely navigate through, so make sure you've achieved at least some math literacy before diving into them. Speaking of navigation, if you're interested in motion planning i.e. how to optimally (safely and efficiently) go from point A to point B, what you read is Planning Algorithms by Steven M. Lavalle http://lavalle.pl/planning/ http://lavalle.pl/planning/ for various ways the math people have came up with to solve this. Many cool applications in fields outside of robotics like in Computer Graphics/Animation too. And btw, if there's one paper you'll absolutely have to read if you find yourself more interested in motion planning is Sampling-based Algorithms for Optimal Motion Planning by Sertac Karaman and Emilio Frazzoli https://arxiv.org/pdf/1105.1186.pdf https://arxiv.org/pdf/1105.1186.pdf in which the authors have revised two very popular path planning algorithms by making them significantly more optimal than their initial implementations were, and are part of many decision making systems that are involved in any type of mechanical movements. Some other comments talked about more advanced disciplines in the field like State Estimation or Reinforcement Learning but I believe the aforementioned (kimenatics/dynamics/motion planning) are the bare minimum before diving into even more advanced math-heavy concepts.

- rramadass 3y agoI have heard good things about Foundations of Robotics Analysis and Control by Tsuneo Yoshikawa though haven't read it myself. Apparently it has a good coverage of the mathematics/equations needed for manipulation/control. Somebody who has already read it might want to chime in.
- xjejux 3y agoIf your robot has sensors, they'll need to be calibrated. This ebook is basically the calibration bible: https://www.tangramvision.com/resources/calibration-desk-reference https://www.tangramvision.com/resources/calibration-desk-ref...
