Pretty happy with the shoulder joint now, it’s able to handle a 370g hammer with the arm hyper extended. Next step is to upgrade the rest of the arm 🦾

Different gearboxes built in the past few days. The first left side one is using planetary gears with a 7.5NM stall torque and tested to be able to handle 4.6NM continuous load. (The stock servo motor is Feetech STS3215 on the right hand side)

Switched back to using a rotary servo motor instead of the linear actuator. Three times cheaper and seems to be way smoother this time
