We need to specify some more parameters of the joint however to get the two objects to rotate relative to another, like your knee allows your lower leg to rotate relative to your upper leg. When you run joints.py now and unpause it, you should see that the two objects are connected: the robot ‘falls’ forward as shown in Fig. This creates a joint that connects the two cylinders together. Joint = sim.send_hinge_joint( first_body_id = whiteObject, second_body_id = redObject ) We are now ready to connect these two objects by placing a line just after the creation of the two objects: 1a, because the two objects are not attached together.Ĭapture a screenshot like Fig.
You should see the red object fall to the ground as inįig. Run joints.py and unpause it using Ctrl-P. Start by making a copy of objects.py and naming the copy joints.py. Joints, like your knees or elbows, connect parts of the robot’s body together and allow them to rotate relative to one another.
In this project you will add a joint to the simulation.
