I made a playable Excel workbook that models a 2D and 3D robot arm using only ordinary spreadsheet formulas, charts, sliders, and Excel Solver. The idea is to make kinematics easier to understand. GitHub: https://github.com/CarlKCarlK/excel-3d-robot-arm The 3D arm is inspired by the old Radio Shack / TOMY Armatron toy robot arm. The workbook lets you move the arm manually, set a target point, and then use Excel's Solver to find the control settings that move the hand to the target (inverse kinematics!). I made this mostly as a learning project. Excel makes the math visible: the rotation matrices, position updates, target error, and Solver setup are all inspectable cell by cell. Nothing is hidden in a robotics library or graphics engine. The model itself is just a series of rows, each controlling one segment. The rows process 3 ways to turn (yaw, pitch, roll) or a move, turtle graphics-style. submitted by /u/carlk22 [link] [Kommentare]

Hey reddit, So we built a gaming accessibility app SensePilot that enable people with disabilities to control a computer and play video games. I just finished developing the human-robot interface prototype so thought I'll share the demo here too as its related to robotics. Hope to eventually apply this to assistive living robots, because their controls are usually very limited and their users are unable to use hands for controlling the robot very well. submitted by /u/SensePilot [link] [Kommentare]

I'm looking to buy a robot arm through AIFITLAB - has anyone done a major purchase through them recently? I'm looking to buy an AgileX NERO, price seems lower than US based companies which I know might be due to tariffs submitted by /u/Vassaci [link] [Kommentare]

During NY Techweek, Arc League, presented by Katena, demonstrated the teleoperated suit with robot boxing and dancing. I know there has been a lot of humanoid hype, but as a roboticist watching it up close, I'm still quite amazed how far we have come. submitted by /u/OkThought8642 [link] [Kommentare]

I made a little online multiplayer game inspired by my recent underwater robotics work. You can pilot a little ROV around the ocean, explore shipwrecks, take photos and categorize fish and things. It's multiplayer and I'm thinking of having treasure hunts, etc. Should I ship it? Would you play? submitted by /u/cheese_birder [link] [Kommentare]

I have known sence I was 7 that I have wanted to be a robotic engineer and now it is the summer going into high school and I am already taking as many electives next year but I need to know if there is anything I should do over the summer to help me submitted by /u/GameFoxx1 [link] [Kommentare]
