General Specifications
The number of degrees of freedom is as follows:
| Component | # of degrees of freedom | Notes |
|---|---|---|
| Eyes | 3 | Independent vergence and common tilt |
| Head | 3 | The neck has three degrees of freedom to tilt, swing, and pan |
| Chest | 3 | The torso can also tilt, swing, and pan |
| Arms | 7 (each) | The shoulder has 3 DoF, 1 in the elbow, and three in the wrist |
| Hands | 9 | The hand has 19 joints coupled in various combinations: the thumb, index, and middle finger are independent (coupled distal phalanxes), the ring and little finger are coupled. The thumb can additionally rotate over the palm. |
| Legs | 6 (each) | 6 DoF are sufficient to walk. |
Sensors
| Sensor type | Number | Notes |
|---|---|---|
| Cameras | 2 | Mounted in the eyes (see above), Pointgrey Dragonfly 2 (640x480) |
| Microphones | 2 | SoundMan High quality Stereo Omnidirectional microphone, -46 dB, 10V, 20....20 000 Hz +/- 3dB |
| Inertial sensors | 3+3 | Three axis gyroscopes + three axis accelerometers + three axis geomagnetic sensor based on BOSCH BNO055 chip, mounted in the head. (100Hz) |
| Joint sensors | For each large joint | Absolute magnetic encoder (12bit resolution @1kHz) at the joint, high-resolution incremental encoder at the motor side, hall-effect sensors for commutation (brushless motors only) |
| Joint sensors | For each small joint | Absolute magnetic encoder (except the fingers which use a custom hall-effect sensor), medium-resolution incremental encoder at the motor |
| Force/torque sensors | 6 | 6x6-axis force/torque sensors are mounted on the upper part of the arm and legs plus 2 additional sensors mounted closer to the ankle for higher precision ZMP estimation (100Hz) |
| Tactile sensors | More than 3000 (*) | Capacitive tactile sensors (8 bit resolution at 40Hz) are installed in the fingertips, palms, upper and fore-arms, chest and optionally at the legs (*). |
| Task | Description |
|---|---|
| Crawling | Using visual guidance with an optic marker on the floor |
| Solving complex 3D mazes | Demonstrated ability to navigate and solve intricate 3D mazes |
| Archery | Shooting arrows with a bow and learning to hit the center of the target |
| Facial expressions | Capable of expressing emotions through facial expressions |
| Force control | Utilizing proximal force/torque sensors for precise force control |
| Grasping small objects | Able to grasp and manipulate small objects such as balls and plastic bottles |
| Collision avoidance | Avoids collisions within non-static environments and can also avoid self-collision |
