Cut the mild steel bars to form 13 lengths of 87mm bars and use a dremel or similar to smooth the ends slightly (shown below are 87mm bars, but only 9 of them). Also cut the 1 metre smooth steel bar to get 3 sections of 325mm bar and smooth the ends...
Today I finally got a chance for some quality time with the Dremel. I have decided to drive the arms directly with small 9g servos. This meant removing the square bar that connected them and carefully chopping away various protrusions, including the...
An alternative to reducing the weight (which, given that the servos + batteries currently comprise more than half of the overall weight, and cannot be reduced) is to design the frame + legs in such a way that the servos are not supporting the weight...
TL;DR - I built the first version of a leg: I have some goals for the the mechanical design of this open source robot - it doesn't help if you make an open source robot but it requires a $ 500 000 mold! These goals are: Use readily available manufacturing...
General:Twitch is a 3 servo 'hexapod' inspired by a similar robot made by Amino-san from Japan, seen on YouTube. The idea behind this bot is that it's very mobile (on flat surfaces) for a walking robot with only three servos. The simplicity, walking...
Thursday, 16:41, 15/12/202220/12/2022Sorry for the delay, for some reason my brain refused to work these last 5 days, so I didn't work that much on this project log as I wished to. 23/12/2022 For some reason, it seems like this Project log is so...
Powder tried:PowderResultPlaster + Talcum powderNot enough strength both immediately after print and after settingPlaster + sugar + dextrinIncrease wet strength, but very difficult to spread. Also very messy.Salt + dextrinGood wet strength, improved...
I started by cutting all the lengths of steel box section to length according to the chassis design. Next i made the hydraulic wheel motor mounting plates. I used a compass and pencil to mark up for the large holes that took the body of the hydraulic...
With a little dremel work and sanding I was able to nicely seat a mini Corsair keyboard that was removed from its housing. I had also liked the idea of wrapping a Zaps cable with the aviation-style GX16 connector around the bar used for the fax...
I just wanted to detail the construction of the portable device.For all point to point connections, see the schematic. For the most part.. Just build the schematic. Note. The button wiring may be different in the finished device, but this can easily...
Well I caved and purchased a mid tier Proxxon rotary tool and matching drill press and mini vise. I already had acquired a Proxxon KT 70 compound X-Y table before which works with the press as well.This tool is far more stable, with minimal run out compared...
