IMPORTANT This explain to execute the code in a Linux environment with python 3.7 In first place must be ensure that the Webots simulator is running and loaded the fire.wbt world, the simulation must be paused and at the begining (second 0). 405.4.1 Isolation of the balance algorithm. 26ĥ Revision/Validation of the model 275.1 Gyroscope. 254.8 Improvements of the communication speed. 153.2.3 Motion Manager in asynchronous mode. 8ģ Calibration 93.1 Improvement of the model. The first one extends the standard functionalities of e-pucks under Webots (i.e., microphones, speakers, bluetooth). In Webots and is now distributed with eachġ Introduction 31.1 Context. The whole project has been fully integrated Robot window developed in order to interact Process of transferring a controller to the To the actuators of the real robot in real time State of the sensors and sending commands Order to allow running controllers on theĬomputer from Webots and interact with the In this project we try to realize the developed kinematic of SoftServe for Gazebo under webots. Therefore, the joint angles for the leg motors must be calculated when a or none command velocity is received. The goal is to control the spot via a teleop. Has been made in order to allow the use ofĬontrollers made in simulation on the real This is a ROS 2 package to simulate the Boston Dynamics spot in webots. ![]() The native robot API being very differentįrom Webots API, a cross-compilation tool Write in order to be used with Webots API. Processing, motion playback, etc.) has been Of the robot API (walking algorithm, image FurthermoreĪ library containing the main functionalities Then, the robot controllers can be transferred to real robots (see Figure 1-2). Webots allows the experimenter to design, program and simulate virtual robots which act and sense in a 3D environment. This integration has been divided in threeġ) Creation of a simulation model of the robot.īattery, the numerical model of the robot hasīeen calibrated very accurately. Webots is a fast prototyping and simulation software developed by Cyberbotics Ltd., a spin-off company from EPFL. The aim of this project was to fully integrate Mobile Robot Modeling, Simulation and Programming The reason for this could be mismatched motor limitations or parameters for hip, shoulder, elbow in the SpotKinematics.py and LegKinematics.py or project, 2012-13, section of microengineeringīiorobotics Laboratory (BioRob)CyberboticsīioRob & Cyberbotics Abstract Master Thesis When moving in z, the spot does not go completely to its knees.Īlso, the teleop allows the movement to overshoot, so the robot falls. Moving in x,y,z and roll, pitch yaw almost works. The spot_teleop_keyboard sends GaitInput.msg recevied by the spot_driver. To calculate YawRate_desired the self.yaw_inst is set by reading the rotation field of the robot itself. Path planning + line following using a robot. SpotRightLeg.proto and SpotLeftLeg.proto to the limitations from SoftServe found in e.g. I added touch sensors on the feet for all legs to detect contact with the ground used for GenerateTrajectory().Īlso, i changed the min/max position for the leg motors inside the Spot.proto resp. The env_tester.py and gui_spot.py are integreted in spot_driver.py. Only the height is set to 0.84 instead of 0.6, according to the original dimensions found from Boston Dynamics docs.Īt a height of 0.6, the spot stretches its legs and falls to the ground when the simulation starts. The python scripts for the invervse kinematic: Bezier.py, LegKinematics.py, LieAlgebra.py and SpotKinematics.py are nearly untouched. The leg kinematic of the spot is ported from the SoftServeSAG robotics_spot repo. ![]() Ros2 run spot_teleop spot_teleop_keyboard
