Abstract

Example embodiments relate to robotic arm assemblies. The robotic arm assembly includes forearm and upper arm segments. Upper arm segment includes distal motor. Robotic arm assembly includes elbow coupling joint assembly connecting distal end of upper arm segment to proximal end of forearm segment via a serial arrangement of proximal and distal elbow joints. Proximal elbow joint is located between upper arm segment and distal elbow joint. Distal elbow joint is located between proximal elbow joint and forearm segment. Proximal elbow joint forms proximal main elbow axis. Distal elbow joint forms distal main elbow axis. Elbow coupling joint assembly includes distal elbow joint subassembly connected to forearm segment. Elbow coupling joint assembly includes proximal elbow joint subassembly connecting upper arm segment to distal elbow joint subassembly. Proximal elbow joint subassembly is configured to be driven to rotate forearm segment relative to proximal main elbow axis.
