Replace external force with an internal force

In summary, the conversation discusses the possibility of using solenoids or motors to replace the external force of a ball hitting the bat in a haptic device for a baseball simulator. However, it is noted that this may not provide a natural recoil-like feel. Alternatives such as using a high mass or a gyroscope are also discussed, but they come with their own challenges and may not be suitable for a wireless haptic device.

Hi guys. I am working on making a haptic device for a baseball simulator. Now the problem is that I want to replace the external force for the ball hitting the bat with an internal force in my bat-like device using either solenoids or motors. Do you think it is possible to replace the external force and still get a recoil-like feel on the bat?

It won't really work. This is why: There are two ways to achieve some similar effect like a recoil.
1) Actually recoil something inside the bat. You could use a high mass that wouldn't need to be speed up as much as a ball, but you would have to catch it again inside the bat which would produce a very unnatural force.
2) Do something funky with a gyroscope, but these things would normally turn the bat in weird directions. You could spin the gyroscope up slowly though in a direction counterclockwise to the bat swing, and hit the breaks suddenly the moment you simulate the hit. Gyroscope physics are a ***** though and the bat will be have in a strange way when your swing is not in the right plane of motion.

hey thanks for that. I did consider gyroscope, but apart from the difficult control, it'll make the bat heavy and defy the whole purpose of a wireless haptic device.
 

1. What is meant by replacing external force with an internal force?

Replacing external force with an internal force refers to the concept of using internal resources and mechanisms to achieve a desired outcome, rather than relying on an external force or factor. This can involve utilizing one's own skills, knowledge, and abilities to overcome challenges and achieve goals.

2. Why is it important to replace external force with an internal force?

Replacing external force with an internal force can lead to greater self-reliance and self-sufficiency. It also allows for a more sustainable and long-term solution to problems, as it is not reliant on external factors that may change or be unavailable.

3. How can one effectively replace external force with an internal force?

To effectively replace external force with an internal force, one must identify the external factors or forces that are currently being relied upon and find ways to utilize internal resources instead. This may involve developing new skills, seeking support from others, or finding alternative solutions.

4. What are the benefits of replacing external force with an internal force?

The benefits of replacing external force with an internal force include increased self-confidence, self-reliance, and resilience. It also allows for a deeper understanding and utilization of one's own capabilities and strengths.

5. Can replacing external force with an internal force be applied to all situations?

While it is not always possible or practical to completely replace external force with an internal force, the concept can be applied to many situations. It may require creativity and adaptability, but utilizing internal resources can often lead to more effective and sustainable solutions.
