How can two DC motors move a robot in various directions?
DC motors can be run both forwards and backwards depending on the direction of the applied current. Special circuits called “H-bridges” allow the use of switches and transistors to change the direction a motor moves without having to change any of the wires.
How much weight can DC motor carry?
The maximum torque is given as 1.2 kg*cm (which includes the gearbox-transition), which means having wheels with an radius of 1 cm (or 2cm in diameter) will give you a force that is equivalent to 1.2 kg in weight at nominal voltage, as long as your electronics can provide a current of 300 mA (load current).
How do robots select DC motors?
10 Steps to Choosing the Right Motors for Your Robotic Project
- Step 1: Determine the total weight and traction requirements.
- Step 2: Calculate the traction wheel rotation speed.
- Step 3: Calculate the traction motor power/torque.
- Step 4: Calculate the lifter motor rotation speed.
What is DC gear motor?
A Direct Current (DC) motor is a rotating electrical device that converts direct current, of electrical energy, into mechanical energy. An Inductor (coil) inside the DC motor produces a magnetic field that creates rotary motion as DC voltage is applied to its terminal.
How do you rotate a DC motor?
Your DC motor can be configured to turn in either direction by simply inverting the polarity of the applied voltage. The change in the flow of current switches the direction of the spinning force, causing the motor’s shaft to begin turning in the opposite direction.
What type of DC motors are used in robotics?
Stepper Motor Controllers: used with unipolar or bipolar stepper motors depending on their kind. A brushed DC motor is one which uses two brushes to conduct current from source to armature. There are several variations on the brush DC motor, but permanent magnet DC motor (PMDC) is used extensively in robotics.
How can I make a DC motor stand upright?
Assume your two ball-launching wheels are in a horizontal plane. Now imagine that the DC motor is under one of the wheels, with its shaft also horizontal, but in line with the two ball-launching wheels’ centers, so if you put a small wheel on the motor’s shaft, it will be upright.
How do you control a DC motor from the battery?
By the term controlling I mean both direction control and the speed control. The direction of the DC motor can be reverse by simply reversing the polarity of the battery connection. The speed of the motor can be control by changing the voltage level and dc voltage level can be changed by PWM signal.
How to drive two different loads from one motor?
Well, You question is unclear, But as far as I understand You can drive two different load from a single motor by making a correct mechanical gear box assembly. You can rotate two wheels into two different directions with the use of proper gear system. Thanks for contributing an answer to Robotics Stack Exchange!
