We decided that the standard motor on the QuadROSbot was not suitable for travelling over rough ground at slow speed - it was more suited to speed rather than torque. The motor chosen for the upgrade was a 3 phase 48 V DC motor with a 5:1 planetary gearbox...

In previous projects we spent a lot of time designing and building the mechanical systems and we really wanted to short cut all the hard work by using a ready made system that could be bought reasonably cheaply 'off the shelf'. We looked at mobility...

The fragile alginate negative impression is used as a mold to create a tough heat resistant positive impression. The positive impression will be used to form the specialized dental thermoplastic sheets into ultra-thin ultra-clear retainers. I use Bondo...
List of parts to be 3D printed and the required hardware components A Handle to house the motor and batteries for actuation. This component has been reused form one my previous projects, Enchanted Thor Hammer. Refer to the list of 3D printed parts...
Assemble materials. If possible, try the mechanical switches to suit your hands. I used the Cherry MX Clear for all buttons. Perhaps, MX Blue would be better for Alt, Control, and Shift. Anyway, for the top boards you need "Tactile", and for the bottom...
For each of the Elevon servos, repeat the same procedure as above, but with a servo arm approximately 9.5mm hole-to-center (3/8 Inch). This length can be a bit longer or shorter, the effect is increasing or decreasing elevon control throw. For servos...
Reflow for 0603 parts and the QFN32 FPGA should be pretty reliable, but issues can arise. The 0603 parts may tombstone or become otherwise unaligned and need to be fixed by hand. A soldering iron and wick will work well for this.If the FPGA IC is not...
Eitherget a UBW32 for the CPU. plenty of online retailers for this. proceed to step 2, orget an Olimex Duinomite-mini (which I use), or Duinomite with the IO adapater (which I do not have, but reportedly it also works). If you use these boards,...
PrepareGet a nice work area ready. You'll want plenty of space to assemble everything as well as paper towels and gloves -- epoxy is sticky! It's a step everyone wants to skip, but making sure you have everything laid out and ready to go will help you...
This has been a pretty grueling bootcamp, but you should now be comfortable with basic logic gates including AND, OR, NOT NAND, NOR, and XOR. You should know about flip flops and the difference between sequential and combinatorial logic. There's plenty...
CalibrationCalibrating the X/Y-axis of a plotter or CNC machine is actually quite easy. I did it as described in this video. First i had to know the theoretical steps/mm per axis. To calculate this value I multipliedthe steps/rev. (200 for most NEMA...
Interlude:At this point I decided it was a good time to replace the battery, before it leaked or died. This wipes the patches from memory, so if you want them then make sure you have saved them and know how to restore them using SYSEX or tape.The original...
