Certainly a challenge that increases in complexity with the newer six DoF biped. We will be modeling velocity and torque control too.

Update 5: Building a Bi-ped Robot With Aditya Tiwari leading the front on Simulation and General Software. For the 4DOF system, One of the key challenges faced during the simulation process was the accurate modeling of the robot in the Unified Robot Description Format (URDF) used extensively in ROS2. Principally, the robot possessed parallel linkages that cannot be modeled in URDF, this necessitated a clever workaround by repositioning the concerned links and adjusting their Inertia values. Furthermore, the incorporation of ROS2 control required a significant investment into the control manager and the hardware interface which took time and effort to circumvent. simultaneously, the mechanical team started designing the 6 DOF system. #PrototypeDevelopment #mechanicalengineering #humanoidrobots #controlsengineer #problemsolving #EngineeringChallenges #pid #bipedRobots

Linear Pendulum Gantry Response to a 4N input force for 180ms. This exercise is used to find the system parameter values and to validate the mathematical model. Once the model is validated, a controller can be designed and implemented. An EMB rotary encoder measures the pendulum angle and an EMB linear encoder measures the cart position. An EMB actuator with a rack and pinion provides the input force to the cart. Data available for download (free) in our GitHub, for input forces of 2N, 3N, 4N, and 5N. Data includes time [s], force [N], motor current [A], cart position [m], and pendulum angle [rad]. Sampling time is 0.001s. Hardware: - EMB-AM4 - EMB-MM2 - EMB-LM1 - EMB-SM1 - EMB Pendulum attachment - EMB Rack attachment - EMB DAQ1 - Power supply - Maxon ESCON (in current mode) Software*: - pysimCoder - NuttX - RTScope * a special thank you to the open-source community for developing and maintaining these amazing tools! #robotics #controlsystems #engineeringeducation #engineering #mechatronics

Short clip from Part 7 of our "EMB with pysimCoder" tutorial series. Using the modularity of EMB, students can create more complex plants such as a pendulum on a cart with a spring and damper. An EMB rotary encoder is used to measure the pendulum angle (green signal) and an EMB linear encoder reads the cart position (red signal). Hardware: - EMB-SM1 (Rotary Encoder) - EMB-LM1 (Linear Slide + Encoder) - EMB Pendulum - EMB-DAQ1 (Real-Time Target) - EMB Spring - EMB Damper Software: - pysimCoder - NuttX #robotics #mechanicalengineering #controlsystems #engineeringeducation #mechatronics

Our success from last week was once again: 💯 ROS and the way we use ROS.💯 🎛️ Sometimes we still program things directly on the robot controller or with PLCs. 🦾 However, if you have somewhat larger and more complex projects, or you want to do some things rapidly, then it's difficult to top something as modern as ROS. 🦾 In fact, we now have a project where four employees — spread over several thousand kilometers worldwide — are working on almost the same piece of code simultaneously, but each with a different level of simulation. 🦾 That's what ROS gives us: huge flexibility for the entire team — regardless of time zones and travel. It's simply fascinating! 🤩 💫 #ROS #programming #robot_control #PLC #complex #project #speed #top #thousands #kilometers #worldwide #spread #code #different #level #simulation #flexibility #total #team #timezone #journey #fascinating

What is ECU Cloning?🤔 ECU cloning, also known as engine control unit cloning. The process of ECU cloning involves completely writing the EEPROM and FLASH data of the original car ECU to the adventive ECU (including programming, coding, anti-theft, VIN, learning matching and other data). The ECU is an electronic control module responsible for all aspects of engine operation. Such as fuel injection, ignition timing and emission control. #magicflex #garagetoolstips #garagetips #automaxtools #toolstips #mechanictips
