Build Sessions
The guided journey from cold-start to a finished Dropbear. Each session is one sit-down chunk of work — usually 1–3 hours, ending in a verifiable artifact.
Torso Assembly
A futuristic, rigid robot torso — square, light, holds its shape under hand-twist. The first part of your Dropbear that exists in the real world.
Pelvis & Hip Assembly
The pelvis subassembly — the load-bearing bridge between torso and legs, with hip pitch/yaw/roll mounts ready for actuators.
Left Leg Assembly
The left leg from hip to ankle — femur, tibia, knee revolute, ankle pitch/roll. Articulates freely once actuators are mounted.
Right Leg Assembly
The right leg — mirror of the left. Same instructions, mirrored parts. About 30% faster the second time.
Left Foot
The left foot — a smart sensing platform with four 50kg load cells embedded in TPU pads. Dropbear feels the ground through this.
Right Foot
The right foot — mirror of the left. Same sensing platform, same process.
Left Arm & Hand
The left upper limb — shoulder yaw/pitch/roll, elbow, wrist, and the Aero Hand with five tendon-driven fingers at 7 DoF, 16 joints, 389 g.
Right Arm & Hand
The right upper limb — mirror of the left. Same instructions, mirrored parts.
Head — the Egg
The Dropbear head: Stewart platform with 6-DOF motion, camera, Jetson Orin running local LLM. The face that talks back.
Full Robot Integration
All nine subassemblies joined into a standing Dropbear. First full-body power-on: every joint alive, sensors live, the robot as a system for the first time.
