    Degree of climbing

    rajkiransingh

      Hi

      Am designing a bot , basically which will be moving on the smooth surface (as glass).

      The total weight of the bot is around 7kg to 9 kg.

      Am i wana use 2 motors.

      Climbing angle 0 to 40 degree

      Please let me know about which type of motor is should use, what should be the torque, speed etc.,

       

      Please guide me if you have got better solutions

          At 40 degrees it takes about 5.8 kg to lift a 9 kg bot, which is 57 N.

          To calculate the torque, multiply by the radius of your drive wheel or drive gear.

          Add 10% to 20% for friction losses in your drive train.

          Divide by the number of drive motors.

          Add a safety factor.

          You can calculate speed by how fast the circumference of your drive wheel is moving at this torque.

          Note, you will need a pretty good coefficient of friction on your drive wheel to avoid slipping  on a 40 degree slope.

            You will also have to build so that your robot's center of gravity stays within the wheel base at the angle of the incline.
