Have you ever thought about how humans walk?
A walking robot must also alternate its two legs to move forward, and to achieve this leg exchange, a crank-rocker mechanism is used, which is a common type of machinery. The crank-rocker mechanism is the most basic form of a four-bar mechanism, consisting of a crank and a rocker connected by a hinge.
Characteristics: The crank performs a full rotation as a rotating pair, while the rocker swings in an arc. The crank-rocker mechanism can be divided into two states based on the active and passive forms: First: The crank is the active component and rotates at a constant speed, while the rocker is the passive component that performs variable speed reciprocating motion, with the connecting rod performing planar compound motion. For example: the crank acts as the active component—driving a ratchet mechanism;
Second: In the crank-rocker mechanism, the rocker can also act as the active component, converting the rocker’s reciprocating motion into the crank’s rotation. For example: the rocker acts as the active component—a sewing machine foot pedal.
Now let’s get hands-on and make it together~
Assembly Steps
Assemble the torso structure
Fix two cranks on the motor hexagonal shaft, ensuring that the two cranks are installed 180 degrees apart.
Assemble the leg structure
Since the robot has two legs, we need to assemble two identical leg structures.
Assemble the leg support structure
1. Ensure left-right symmetry;2. Combine to form a crank-rocker mechanism.
Install the head
Attach the horn to serve as the head.
Connect and wire the mainboard and battery box
Connect the battery box to the power interface, the horn to the horn interface, and the motor to the left wheel interface.
Is the assembly complete? Let’s take a look at the finished product~
Quickly give it a try,
and see if your robot walks steadily~
If it doesn’t walk steadily,
how can we improve it?
Think creatively~
We look forward to your better ideas……
