SUMMARY

This discussion focuses on designing a human-powered claw mechanism capable of grasping objects weighing up to 2.2 lbs, utilizing pulleys, levers, and gears. The user seeks assistance in creating a functional design that mimics the scissor action for effective gripping. Prototyping is suggested as a crucial step in the development process, emphasizing iterative design and testing.

PREREQUISITES
  • Understanding of mechanical advantage in levers
  • Basic knowledge of pulley systems
  • Familiarity with gear ratios and their impact on force
  • Prototyping techniques for mechanical devices
NEXT STEPS
  • Research mechanical advantage principles in lever systems
  • Explore different pulley configurations for optimal lifting
  • Study gear ratios and their effects on torque and speed
  • Learn prototyping methods for mechanical designs, such as 3D modeling
USEFUL FOR

This discussion is beneficial for mechanical engineers, hobbyists in robotics, and anyone interested in designing human-powered mechanisms or grasping devices.

Ok for this project I'm supposed to build a vehicle that is human powered (the easy part). the hard part is, I have to make a claw that will be able to grab things like erasers, balls, and a bucket with a 2.2 lb weight in it. It will also have to be able to grab a ball from a stool and place it on the ground and visa versa.

Can anyone help me on the design onf the claw? IT has to be made out of pullys levers and gears. Actually just 2 of the 3. Any input would be greatly appreciated :smile:
 
Physics news on Phys.org
use the idea of scissors where the blade is the claw, we can't design the whole thing fo you now can we.
 
hey... th ats actually a really good idea! lol thanks for the tip.

i'll try to devise some prototypes
