Joint / actuator fault or unusual motor noise
A limb joint reports a fault, stiffens, or makes grinding / clicking noise during motion.
Quick answers
What you might notice
- Joint error on controller/app
- Stiff or locked joint
- Grinding or clicking from a limb
Can I fix this myself?
Difficulty: hard · about assessment. If unsafe or unresolved, use meetup / mail-in repair.
What you need
- Soft dry cloth
- Manufacturer diagnostic app / remote
Do this
- Stop motion immediately and place the robot in a safe, supported pose on a flat floor with clear space.
- Power-cycle after the joints settle. Check for loose covers, debris around joint housings, and cable pinch points.
- Run the vendor diagnostic / firmware check if available. Do not force a jammed joint by hand.
- Actuator replacement is specialist work — book Brisbane meetup assessment or Queensland mail-in if the fault returns.
Parts
