    Does anyone know where I can pickup a mount for an MFA 940D which I picked up from Maplin ? Thought it came with a mount but apparently not. MFA website doesn't list it. The gear box has a diameter...

    I am pretty sure you are right. I found a T30 and that's too big. Ordered a set anyway.

    Congratulations on Shu!'s performance at the event. I reread the build thread to see how you controlled the limits on the arm. But failed to see how you did this. Do you use limit switches and a...

    You could be right. I never saw a 12v they were out of stock at the time. Too late unfortunately. Other one is in same condition. What size driver do I need? I assume they are the same. I'll...

    Some measurements were taken back last year when I was looking for better mounts, and struggling with fitting wheels to the demo bot. Since then I bought a caliper gauge so I'll post these...

    Hey all, Decided to untangle and disassemble the Argos 14.4V drills I used in my demo bot. In making the demo bot, I removed the battery and unscrewed the few screws holding the two sides of...

    For the on off switch just put a xt60 or similar on the positive wire. Basically a giant jumper. Straight after battery cut the positive wire. Wire one end to + side and other end to - side of...

Merry Christmas and Roboting New Year

by Deathly Hallows on 28th December 2017 at 20:47
There was a theme to my Christmas presents this year, you couldn't guess?

A bench drill and vice
A Dremel 3000
Even a robot themed notebook and pen
The wife even got me thermals so I am warmer in garage

I also got a Maplin and had an Argos voucher from my birthday
The Maplin voucher I spent a few pounds on more accessories for the Dremel
The Argos voucher I am putting towards a Dremel Versatip

All I need is some parts to arrive

Too many choices!

by Deathly Hallows on 2nd December 2017 at 10:57
I have been reading Ant threads recently.

There are too many choices. There are so many cool ants out there and they look cheap to make. They are definitely on my to do list. But I have to keep focused and finish a Beetle and a Feather as I originally planned.

I am ironing out the issues I had discovered in rendering the Beetle "Evil K'Weevil" in CAD. Initial design was over weight, with the original shape the surface area (so armour required) was too large,

Is designing as much fun as battling?

by Deathly Hallows on 16th November 2017 at 22:31
I am really getting into the designing part of the sport.

Spent ages trawling websites like Robotshop, Dx.com, technohotsonline, eBay and Amazon. As I am working on a beetle weight is critical. I am also getting to grips with OnShape. I am able to model most simple things that a vendor has a drawing for. Motors, hubs, wheels etc. The built in mass calculator also shows just how much I save by narrowing a plate from 2mm to 1.5mm or drilling out holes. This is making the exercise

Getting into OnShape

by Deathly Hallows on 11th November 2017 at 21:24
I came across OnShape and really like the tool based on my limited experience.

Here is the website

For an expert this is probably really easy, but I am rather new to this so it's taking me a while to really be able to do very much. What I like is the structured approach, powerful tools, 3D rendering, materials built in, and access to massive set of pre-built objects.

So far I have only managed to make HDPE planes with slots cut or holes countersunk. But

It's alive!

by Deathly Hallows on 10th November 2017 at 09:05
The wheels are fitted at least to the level I need now. M10 bolt padded out to ensure central and then washer and nut to clamp the wheel. It will do for my test bed.

Now I need to work on designs here are a few concepts I am playing with:

Code name: Evil K'Weevil
Weight: Beetle (could be scaled up)
Body: Flat
Drive: 2x2, any way up
Weapon: Core Cutter

Code name: Ali-grater
Weight: Feather
Body: Angled wedge to assist self
