A mechanical toy car (without electronics) should turn on detecting obstruction

In summary, the conversation discusses the possibility of creating a toy car that can detect and avoid obstructions using purely mechanical means. However, it is deemed nearly impossible to achieve this task without any electrical components. The group considers using a non-contact sensor and a leg mechanism to push the car out of the way of the obstruction.

HI all.
I wanted to make a toy car (except battery and motor completely mechanical) which should turn and move along on detecting an obstruction. I saw such a toy car but unable to get the design. Please help guys...

Not really feasabile to do it by mechanical only. You can do a mechanically programmed car that will move in a certain pattern but not one that will adapt.

The problem boils down to:

Input -> Signal interpretation -> Action

Using purely mechanical means input and signal interpretation are incredibly difficult (read nearly impossible) to achieve.

The action part is really easy, that could be done by rotating a steering wheel by hydraulics or pneumatics or an electric motor that turns a wheel.

Dude Even i was amazed but our sir showed us that and told it is done using some gears and the toy costs less than 100 rupees. It is possible dude ...

Let us know the details then.

When you say 'detecting an obstruction'. Can the car touch the obstruction? If yes then it can be done mechanically, if not then it can't.

I immedately thought of avoiding the obstuction, which requires a non contact sensor. As such the sensor itsself will have an electrical output.

It will touch and then turn ...
Do u no how?

Some sort of leg out front that when it touches an obstruction, will push the car backwards and the front wheels to the side enough times to get it out of the obstructions way. The foot would run all the time (connected to the drive shaft).
 

1. How does the mechanical toy car detect obstructions?

The mechanical toy car has sensors attached to its body that can detect physical objects in its path. These sensors work by sending out a signal and measuring the time it takes for the signal to bounce back. If an object is detected within a certain distance, the car will stop and change direction.

2. Can the sensitivity of the obstruction detection be adjusted?

Yes, the sensitivity of the obstruction detection can be adjusted by changing the distance at which the sensors will trigger the car to stop and change direction. This can be done by adjusting the placement or angle of the sensors.

3. Will the mechanical toy car turn in the same direction every time it detects an obstruction?

No, the direction in which the car turns after detecting an obstruction is random. This is because the car's sensors are placed at different angles, so the signal may bounce back differently each time an obstruction is detected.

4. What happens if there are multiple obstructions in the car's path?

If the car detects multiple obstructions in its path, it will stop and change direction each time an obstruction is detected. However, if the obstructions are too close together, the car may not be able to change direction and will remain stopped until the obstructions are moved.

5. Is there a limit to the size of obstructions that the car can detect?

Yes, the size of obstructions that the car can detect depends on the range of the sensors. If an obstruction is too small or too far away, it may not be detected by the sensors and the car will continue moving. However, if an obstruction is too large or too close, it may trigger the sensors at a distance that is too short for the car to change direction effectively.
