A mechanical toy vehicle (w/o electronic)

Click For Summary

Discussion Overview

The discussion revolves around designing a mechanical toy vehicle that can navigate a path and turn to avoid an obstruction without the use of electronic motors. Participants explore various mechanical solutions and constraints related to the vehicle's movement and design parameters.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant suggests using a launching or propelling system to navigate the vehicle, emphasizing the need for a non-motorized solution.
  • Another participant inquires about the type of vehicle (land, sea, or air), budget constraints, and specific turning requirements, proposing that wind-up mechanisms could replace electronic motors.
  • A similar response reiterates the need for clarification on the vehicle's turning distance, direction, and number of turns, while suggesting various mechanical alternatives like oven timers and strings to facilitate movement.
  • A participant specifies a budget of no more than $150 and outlines the distance and width constraints for the vehicle's path.
  • One participant expresses frustration at the vagueness of the requirements, indicating a lack of sufficient detail to provide further advice.

Areas of Agreement / Disagreement

Participants have not reached a consensus, as there are multiple competing views on the design approach and mechanical solutions. Some participants seek more details to refine their suggestions, while others find the requirements too vague.

Contextual Notes

The discussion highlights limitations in the clarity of the project requirements, including the specifics of the vehicle's turning mechanics and the constraints of the environment in which it operates.

Who May Find This Useful

This discussion may be useful for individuals interested in mechanical design, particularly in educational settings or DIY projects involving non-electronic propulsion systems.

Using some kind of launching/propelling system to launch a vehicle (toy size)...
The problem is getting the vehicle to turn at a certain point to avoid the obstruction w/o using any type of motor.
I've tried to look into zigzag patterns, but they all require electronic motors w/ gear shafts.. but i need something that's not motorized.

Vehicle? Land sea or air? Budget? Ten dollars or ten thousand?

I'll assume a small wheeled vehicle for a school project.
Does the distance after which it needs to turn change?
Does the direction it needs to turn change?
How many turns does it need to make?
Electronic motors can be replaced with wind ups. Oven timers can be rigged to engage other mechanisms. strings that wind around driven axles can pull a pin or sim. after a set distance. A wind up motor and a crank to the steering axle is an easy way to get zigzagging. There are many other paths to go down depending on budget and application

Budget: no more than 150. Distance is around 9-12 meters (straight path) with an small obstruction being at midway range. The toy vehicle must stay within 2 meter width of the path.
 
Your requirements are too vague for me to offer any more advice, good luck.
