Breaking hard ground with motors

Click For Summary
SUMMARY

The forum discussion centers on selecting an appropriate motor for breaking hard ground, specifically for a robotic tiller design. The original poster (OP) considers using a 1 kW electric motor and a 3-pound hoe, with a target depth of 6 inches and a speed of 5 mph. However, experienced users highlight that roto-tillers typically require around 5 kW of power and that the OP's calculations regarding battery capacity and motor specifications need refinement. The conversation emphasizes the importance of understanding agricultural practices and the mechanics of tillage before finalizing the design.

PREREQUISITES
  • Understanding of electric motor specifications, particularly power ratings (kW).
  • Knowledge of battery capacity and current flow (amp-hours).
  • Familiarity with agricultural tools, specifically roto-tillers and their operational requirements.
  • Basic principles of mechanical design and robotics.
NEXT STEPS
  • Research the power requirements of roto-tillers and similar agricultural machinery.
  • Learn about battery technologies suitable for high-capacity applications, such as lithium-ion batteries.
  • Investigate the mechanics of tillage and soil penetration techniques.
  • Explore materials used in robotics, focusing on the durability of aluminum versus stainless steel.
USEFUL FOR

This discussion is beneficial for robotics engineers, agricultural technologists, and hobbyists interested in designing robotic farming tools or optimizing existing agricultural machinery.

You have not established that issues with agriculture in LDCs is due primarily to production.
You have not established that the issues with food production are limited by planting rate.
You have not established that planting rate in LDCs could be improved with robotics.
You have not established that even if planting rate in LDCs could be improved with robotics, that farmers in LDCs could buy them. If these are intended as charity, that robots are superior to equivalent cash donations.
You have not established that even if all the above were true that there exists battery technology to power this up.

But you're worried about the outer covering of these robots.
Do you understand why this does not look like you are being serious?
