Need help with structure of stair climbing robot

In summary, the conversation discussed designing a robot with a sliding motion and the difficulties in determining the mechanical structure responsible for this motion. Suggestions were given, such as using a belt or chain with a stepper motor, or creating a rack and pinion design. The conversation also questioned the presence of motors on the wheels.

Im supposed 2 design a robo like this 1, but here, the mechanical part seems more tought thn the electrical and programming. I couldn’t make out what mechanical structure is being used to have this type of motion. Can anyone please help.



Here’s a start:
There r 2 motors attached in the centre part of the robot, which keeps sliding back anf forth.
But, I can’t figure out out is the motor shaft being coupled to the structure, and how does it have tht kinda motion.

The sliding motion looks to be from a belt or chain. Utilizing a stepper motor with a chain or belt would allow you to count how many steps it takes to move a fixed point on the chain from one end of the track to the other. The fixed point on the chain or belt is attached to a pivoting mechanism (probably another stepper motor) within the body of the robot... inside the track that it slides on is probably a wire ribbon similar to that of the inside of a printer which would power the motors for the wheels. That's just me dissecting it with my eyes though.

OR... if you don't want to use a chain or belt, you can make a rack and pinion design to create the sliding motion.

i can't see any motors attached to da wheels, r thr motors?
 

1. How does the stair climbing robot maintain its balance?

The stair climbing robot uses a combination of sensors and algorithms to maintain its balance while climbing stairs. These sensors detect changes in the robot's orientation and send signals to the control system, which then adjusts the robot's movements to prevent it from toppling over.

2. What type of materials are used to construct the stair climbing robot?

The materials used to construct the stair climbing robot vary depending on the specific design and purpose of the robot. However, most stair climbing robots are made from lightweight and durable materials such as aluminum, carbon fiber, and plastic. These materials help to reduce the robot's weight and improve its mobility.

3. How does the stair climbing robot detect and navigate stairs?

The stair climbing robot uses a combination of sensors, such as ultrasonic sensors, infrared sensors, and cameras, to detect the presence and height of stairs. The robot then uses this information to plan its movements and adjust its legs to climb the stairs. Some stair climbing robots also use machine learning algorithms to improve their navigation and adapt to different types of stairs.

4. Can the stair climbing robot carry heavy loads?

The ability of a stair climbing robot to carry heavy loads depends on its design and purpose. Some robots are specifically designed for heavy-duty tasks and can carry loads of up to 100 kilograms or more. However, most consumer-grade stair climbing robots have a weight limit of around 20-30 kilograms. It is important to check the specifications of a specific robot to determine its weight-carrying capacity.

5. How does the stair climbing robot handle different types of stairs?

Stair climbing robots use different techniques to handle different types of stairs. Some robots use a combination of crawling and hopping motions, while others have rotating or flexible legs to adapt to stairs with uneven or irregular steps. Some robots also have the ability to change their center of gravity to navigate steep or narrow stairs. Ultimately, the design and capabilities of the robot will determine how it handles different types of stairs.
