Makeblock drive wheels for the robot arm
and it can be controlled via iPhone Bluetooth through the arduino bluetooth module attached
old robot arm
found my old makeblock robot arm, while cleaning up the room for my son, another office/work room gone…
Redesigning the TeddyRobot Wheels
the old design was not solid enough and traction too slippery,
this new design will also further reduce the gear to wheel ratio for more torque
Makeblock Lab Kit
Ordered a whole bunch of additional Makeblock components with a 50% discount at EXP Tech.
Now I have enough components to re-create my 3d printer in Makeblock parts. There should also be enough parts left to build a few more wheeled robots for my son, or even a plotter.
FreeNAS 9.1.1 Upgrade
Today I upgraded my FreeNAS storage from 8.3.1 to 9.1.1 with all RAIDZ pools still alive, all new ZFS features available, no problems so far.
Further I printed lots of 90 degree makerbeam brackets, and uploaded all my design files to Thingiverse.
New head mount plate
To put the robot head on top of the maker beam chassis I needed a quick and dirty solution, so I simply cut off a CD jewel case, and used the plate for mounting.
Unfortunately the material, some kind of polystyrol I guess, isn’t very robust, easily to be scratched and simple to break.
Back to the 3D printer and I quickly designed a new head servo mount plate:
OpenSCAD designs for makerbeam spare parts
Only a few days after the maker beam starter kit arrived and I screwed together the robot chassis, already a lot of connector parts are gone.
Especially the 90 degree corners and the 90 degree flat angles.
Instead of ordering the next batch, I decided to 3D print them later, but first the design files:
Makerbeam teddy robot chassis
My makerbeam starterkit arrived, so I migrated the whole robot chassis from 3D printed parts to the more practical extruded aluminium profile beams. This way I can mount additional stuff everywhere and change minor things faster without the need for reprinting.
