Raspberry Pi 2 delivered! This may become the ROS brain in the near future.

First calibration parts #3

RepRap completed #6

RRR robot GUI. The green square indicates the required target position that the manipulator end effector must achieve.

Yet another close-up of the working extruder. The solder which reinforces the copper wire did not show signs of melting from the high temperatures, as it is futher away from the tip, with a large area exposed to the air.

RepRap completed #4

Self-collision checking optimisation in MoveIt! Never in collision

Soldering around the MCU

FSRs held on temporarily with sticky tape.

Booting up

5500 mAh LiPo battery powering Raspberry Pi 2 and Robotis hardware.

The updated Motor Dials, controlling 18 AX-12 motors.

Symmetric foot separation.

Mostly intact after three outdoor practice flights!

RepRap #2 – The soon-to-be son

The push-connectors are fairly hard to press down on, but guarantee a good contact and are much better than screw-based connectors.

A closer view of the mounted extruder.

The idler block is attached to the extruder at the top with two long (40 mm) M3 bolts. The hinged bottom pivots on another M3 bolt (need to cut the excess thread or use a more suitable size).
