Question

i am working on differential driven wheeled robot, a robot is considered as a point mass and navigation is done through artificial potential field, i am able to calculate the linear velocity, but i am unable to calculate the angular velocity. how to get angular velocity?

Answer 1

@kkowdiki here robot is considered as point mass so we can calculate linear velocity very easily.we knoe that the the velocity of centre of mass gives linear velocity of the body .the centre of mass's speed is summation of angular velocity and linear velocity.that is we use following equation:
\[v(due \to translational motion)+\omega \times radius(due \to rotation motion)=total linear velocity of the body \ that is which speed of linear velocity you have got ,half of this linear velocity/radius you will get angular velocity of this point mass but here one thing that it is point mass due to this its radius tends to zero,hence its angular velocity tends to infinity thatb you can not determin.......
