Nowadays, robots are moved not only over smooth surfaces with typical wheeled mechanisms but also for verities of applications a robot needs to travel over rough surfaces. It is difficult to move over rough surface using wheeled and tracked robots. So, the idea of a rough terrain robot appears to ease this situation. From the locomotion of insects and animals, researchers got the idea to invent a multilegged robot that can move easily on the rough surface with legs rather than a wheel. A vast improvement has been made in the sector of rough terrain robots since the 1990s. RHex was the most advanced version of the hexapod robot, with better velocity and stability than other rough surface robots. Over time, many improvements have been made in RHex and other hexapod robots. This paper presents a new design of a rough surface robot of beetle shape; also, can be called as an adaptation of RHex robot. This new model of a Six-legged hexapod robot focuses on mechanical simplicity with minimum power consumption. The model of the robot body is designed without any circular parts, which makes it easier to construct the body with laser cutting. This process also reduces construction costs. Acrylic is used for the body construction to reduce the total weight, and the leg is fabricated using a 3D printer. Using a DC gear motor reduces the complexity of the robot rather than a stepper motor or any other motor because of the simplicity of control. Also, the important thing of this rough surface terrain beetle robot is it uses six motors, one for each leg, which helps to move over various rough terrain with the capabilities to produce a lot of applications. Performance test on different surfaces shows that the constructed robot has the capabilities to perform the movement accurately. This robot can achieve forward movement, running, and turning capabilities with a more straightforward control method using the Android Application.
