Overview
The following is an overview of my project between February and August of 2024, where I was able to work on, and complete my 3D-printed robotic arm.
Features and Specifications
- 6 NEMA Stepper motors
- Gripper servo (max weight yet untested)
- Arduino MEGA 2560
- 12V 10A Power Supply
- 3D-Printed using PLA of various colours.
- KY-0003 Hall Effect Sensors
Lessons Learnt
-
Every problem can be solved with enough creativity and patience.
-
Heating up Neodymium magnets too much can demagnetize them if temperature exceeds their Curie temperature threshold.
-
Do not print PLA if the ambient temperature is high. Heat creep can cause premature melting which may clog the printer head.
-
Ensure polarity of wires connected to a power supply is always correct before connecting this to electrical components (as that can damage them and blow them up!)
-
Ensure the wire gauge used to connect things is appropriate for both the voltage and the current passing through them.
