Designing robots that replicate human interactions is always an exciting challenge. Recently, I created a robotic see-saw model that mimics the classic playground activity. The project combines mechanical design, motors, a linkage mechanism, and a RoboKi controller to bring two figurines to life, pushing up and down as if they're enjoying a real see-saw ride. Here’s how I approached this project and what went into making it a reality.

Step 1: Key Components

  1. See-Saw Frame:
  2. The see-saw is constructed with a balanced frame to ensure smooth motion. I designed it with durable yet lightweight materials to reduce stress on the motors.
  3. Motors:
  4. Motors are positioned on each side of the see-saw, driving the linkage mechanism that controls the figurines' up-and-down movement.
  5. Linkage Mechanism:
  6. A carefully designed linkage mechanism translates rotational motion from the motors into a push-pull action. This mechanism ensures synchronized movement and mimics the natural motion of a see-saw.
  7. RoboKi Controller:
  8. At the heart of the system is the RoboKi controller, which orchestrates the movements of the motors. The controller is programmed to manage speed, direction, and timing to keep the see-saw moving smoothly and realistically.


Step 2: How It Works

Motion Control:

The RoboKi controller operates the motors on each side of the see-saw. It alternates between pushing one figurine up and allowing the other to come down, maintaining the balance and rhythm.

Synchronization:

Using programmed timing, the controller ensures that the figurines' movements are perfectly synchronized. This prevents abrupt stops and jerks, creating a seamless motion.

User Interaction:

While the see-saw is fully automated, you can experiment with the RoboKi controller settings to adjust the speed and frequency of the motion, making the system versatile and fun to observe.

Step 3: Conclusion

The finished robotic see-saw is not only a functional model but also a fascinating demonstration of mechanical and electronic engineering. Watching the figurines go up and down in perfect harmony is mesmerizing and a testament to the power of simple mechanisms driven by advanced control systems.
