Consider an omnidirectional robot with a ring of eight sonar sensors that are fired sequentially. your robot is capable of accelerating and decelerating at 50 cm/s2. it is moving in a world filled with sonar-detectable fixed obstacles. the maximum range of the sonar sensors is 5 m. given the bandwidth of your sonar sensors, compute your robot's maximum speed ensuring no collisions.

The maximum velocity is 2.23 m/s.

Explanation:

Given that,

Deceleration = 50 cm/s²

Range = 5 m

Let the maximum speed of robot is

We need to calculate the maximum velocity

Using equation of motion

Where, v = maximum velocity

U = initial velocity

s = distance

Put the value into the formula

Hence, The maximum velocity is 2.23 m/s.
