Pneumatic Rotary Joint
            Pneumatic actuators, combined with a pneumatic rotary joint, can create rotating joints that utilise compressed air
            or gas. Pneumatic rotary joints enable the transfer of pneumatic power to the actuator while allowing continuous
            rotation. They are often used in lightweight robotic systems or applications that require rapid movements.


            Wheels
            Wheels in robotics are responsible for robot mobility and locomotion.
            Actuators are connected to the wheels to provide rotational motion,
            enabling the robot to  move  and navigate  its  environment. The  type  of
            actuator  used  depends  on  the  specific  requirements  of  the  robot’s
            locomotion system.

            How Actuators are linked to Robotic Wheels?
            To link actuators to robotic wheels, several methods can be used based on the type of actuators. Here are some
            examples:

               • DC Motor-Driven Wheels: DC motors are frequently used to power wheels in robotics, particularly in mobile
              robots. By controlling the speed and direction of the motors on each wheel, the robot can achieve movement
              and navigate its environment. The differential drive and omnidirectional drive configurations are commonly
              implemented using DC motor-driven wheels.
               • Stepper Motor-Driven Wheels: Stepper motors can also be utilised to drive wheels in robots. Stepper motors
              allow for precise position control and are commonly used in applications that require accurate and repeatable
              movement, such as robotic platforms used in laboratory settings or precision manufacturing.
               • Servo Motor-Driven Wheels: Servo motors can be employed to drive wheels in robotic systems that require
              precise control over wheel motion. Servo motors offer accurate position feedback and are commonly used in
              robotic vehicles, drones, or robotic arms where precise movement is crucial

            These examples illustrate some of the actuators used in robotic joints and wheels, but there are many other
            variations and combinations depending on the specific requirements of the robotic system.


                    Controller for a Robotic System

            Control systems in robots are essential for achieving desired behaviours, precise movement, and effective task
            execution. They enable robots to sense their environment, process information, and generate control signals to
            actuate their actuators.

            Controllers in robotics are devices or systems responsible for commanding and coordinating the actions and
            behaviours of robots. They receive sensory input from the environment or the robot itself and generate control
            signals to actuate the robot’s actuators. Controllers play a crucial role in controlling the motion, behaviour, and
            decision-making of robots.

                 The Ecobots from England use bacteria-filled cells to produce electricity from rotten apples and
                 dead flies. These Ecobots (Ecological Robots) are also known to collect energy from the waste in
                 the environment.
