Let’s get back to the main thing we wanted to look at.

pip3 install pybullet –upgrade –user

cd /opt

git clone https://github.com/bulletphysics/bullet3.git

cd bullet3/

cd build3/

cmake -G”Eclipse CDT4 – Unix Makefiles” -DCMAKE_BUILD_TYPE=Release -DBUILD_BULLET2_DEMOS=ON -DBUILD_CPU_DEMOS=ON -DBUILD_BULLET3=ON -DBUILD_OPENGL3_DEMOS=ON -DBUILD_EXTRAS=ON -DBUILD_SHARED_LIBS=ON -DINSTALL_EXTRA_LIBS=ON -DUSE_DOUBLE_PRECISION=ON ..

make

make install

ldconfig

ok that installs it and builds the examples but seems to be for Eclipse CDT. Not sure I need a C++ IDE.

ok so i was supposed to do this for cmake:

./build_cmake_pybullet_double.sh

But anyway,

cd /examples/RobotSimulator

./App_RobotSimulator

COOL.

Ok lets run build_cmake_pybullet_double.sh

ok there we go

cd ./build_cmake/examples/ExampleBrowser

./App_ExampleBrowser

OK this is great.

geometric, kinematic and dynamic models

The geometric model describes the geometric relationships that specify the spatial extent of a given component.

From this website: https:

Kinematics is the study of motion of bodies without regard to the forces that cause the motion. Dynamics on the other hand is the study of the motion of bodies due to applied forces (think F=ma). For example consider orbital mechanics: Kepler’s Laws are kinematic, in that they describe characteristics of a satellite’s orbit such as its eliptical shape without considering the forces that cause that motion, whereas Newton’s Law of Gravity is dynamic as it incorporates the force of gravity to describe why the orbit is eliptical.
