I had a watch of the livestream on the EXR Facebook page and yeah, without zooming in, it is hard to tell what was going on half of the time.

So the post mortem has been done.
The top panel with the slot is bent where Blunt Force Trauma hit it. The original top panel has a few more dings in it but nothing catastrophic. The front bits of the side panels are missing on both sides where Drumroll presumably hit and there is a gash in the panel where Binky scored a direct hit and I think it was that what took the side panel off. Amazingly, the rear panel has come out of it unscathed, a bit more dirty perhaps but nothing a scouring pad couldn't fix.
The wheel on the side which came off looks very poorly but is structurally intact. The rubber needs gluing and screwing in place but that isn't a big job in of itself. Definitely needs a new wheel hub though. The motor which was soldered back to life is still running as is the other motor. In fact, all the drive electrics are still running. The soldered motor is too high up in the shell which explains all the wobbliness. Incredibly, I think the motor shafts themselves are still straight.
The wings are bent, as are the screws holding them in. The tail has come loose and the front and top crossmembers holding the robot together have cracked in weird and wonderful ways plus the castor wheel is loose.
In short, the list of things needed are:
- A new wheel hub
- 2x new wings
- New crossmembers
- A new drive motor
As for the weapon, the motor blew itself apart during the "featherweight fun times" after show match and the mount for that has fallen apart along with the locking pin having sheared in the hub.
None of this is insurmountable, just to get moving under its own steam is going to cost very little (only the £30 for a new crossmember and a wheel hub, less if I can find a second block to act as a crossmember) but it will require a full disassemble/clean/fix/reassemble. However, I do want to concentrate on Kaizen built and getting The Honey Badger 3 ready (been specifying motors and such today) so in short, The Honey Badger 2 is fixable but requires a fair bit of time which I might not have.
It may surface again

Since the last post, I've removed all the electrics/motors/batteries etc of The Honey Badger 2 and left with a rather sad looking shell. As I have Kaizen to worry about along with the upcoming FW championships, I need to get The Honey Badger 3 moving so I've made a decision to transplant the current brushed setup from 2 to 3 and then replace it all with the fully brushless setup later on - I have my eyes on some KEDA 56-63 outrunners as drive motors which look very tasty (https://hobbyking.com/en_us/kd-53-20...ner-195kv.html). Once at the stage of being fully brushless, I'll put all the brushed stuff back into The Honey Badger 2.
So here is the design as promised. A lot of this is subject to change (without reason - a Battlebots reference there) but this is what I want it to look like.

(To be really in keeping, it was drawn on the back of the Robot Wars application I wrote for Kaizen - :P)
Certainly going to be wider than The Honey Badger 2 at any rate, probably about as high as Neophyte for context. The weapon on the back was meant to be a saw but to be honest, anything that rotates can go there or, as the annotation suggests, a spear for non-spinner events.
I had some of the 15mm panelling arrive last night but unfortunately, muggins here screwed up and ordered panels that were too short by about 100mm. That is OK though, they can form part of a internal double deck structure inside the main body so that I do have more usable space in there (I could do that with panels I have now to be honest but it being wider means just that little bit more room). Below is what the main body kinda looks like:

So the idea is that I'll mount the speed controllers and the motors on the lower deck and then have the batteries/fuse/link on the top deck so I can use all of the 100mm wide space available and have the two 50mm high rails underneath which the top deck can mount to so the normal serviceable stuff can be accessed much easier.
Provided the new set of panels work, I might have something driving by next week

Reminds we somewhat of Tanto, good luck with it!
I didn't know which robot got torn up initially, only when the remenants were put in the loading pen I realised. Felt really sorry for you, was convinced it was a write-off. Yet you made it into the next battle!Comment

An interesting looking design, wasn't neophyte quite short? Are you aiming for invertable? Being honest it doesn't look that much wider than 2.0, seems it's going to be a compact little thing and 15mm!? Damn son.
Going to be following quite closely, I can't wait to see the brushless drive take shape, it's going to be pretty nippy with those motors anyway..
When is the FW championship? What sort of timescale do you have?
Sorry, question overload

Neophyte was a huge bot for a feather. I would guess 750mm wide 400-500mm long and 250mm high with the lifter down.Comment

I didn't realise it was so wide in all honesty, maybe that's why it looked quite short... I'll get my coat...Comment

Quite a few did to be honest, myself included for a moment.I didn't know which robot got torn up initially, only when the remenants were put in the loading pen I realised. Felt really sorry for you, was convinced it was a write-off. Yet you made it into the next battle!
As noted, Neophyte is bigger than your typical feather - The Honey Badger 2 in its widest incarnation was 510mm wide. The bodywork on The Honey Badger 3 is 480mm wide plus whatever the wheels are going to be but it is the plough that is the widest point, likely to clock in at 600mm wide, depending on what I end up using for that. I am indeed aiming for invertible, trying to get hold of some specialist RC wheels again that should fit the bill nicely.An interesting looking design, wasn't neophyte quite short?

Yeah, the main bodywork is 450x100mm so very compact, hence the double deck thing. It'll make more sense when I've got that bit built.
Even with the Gimson motors, it is going to be fast. With the KEDA motors, it is probably not going to be substantially faster owing to a low Kv rating but it is unlikely to be stopped in a hurry. The brushed motors (775 type) give out about 215W per side, the KEDA motors are rated for around 1500W. The motors have been ordered anyway.Going to be following quite closely, I can't wait to see the brushless drive take shape, it's going to be pretty nippy with those motors anyway..
Late August I believe but the signups have not been posted yet. As far as timescale goes, if I get it rolling next week, I am on course to have something rolling by EXR Portsmouth as a test day out (I'll only be going for a day). It probably won't have a weapon by then (the spear I might have ready) but the major construction work will have been completed by then.When is the FW championship? What sort of timescale do you have?
Wider than that surely? The Honey Badger 2.2 was 490mm wide and the video I have from the first melee (when Neophyte was upside down) completely covers the Badger at one stage. However, the Badger is taller than Neophyte I think with the lifter down - The main body of the Badger is 230mm high.Neophyte was a huge bot for a feather.

For those who are curious Neophyte's chassis (excluding the lifter arm) is 650x450x150mm. Once you factor in the lifter & wheels it becomes 770x650x200mm. Will probably look at cutting it down a little before the next event. Either way if nothing else I'm glad it has become the benchmark for the size of featherweights.
Also assuming the featherweight championships are being held at the Insomnia festival again then they will be at the NEC in Birmingham on 24th-27th August.Comment

Damn i was not too far off, did you say your where going to Grantham? it is no spinnerComment

Should be at Grantham as long as all goes as planned. Hopefully should get some proper driving practice in.Comment

After the ordering mishap, the new, longer panels arrived and for your viewing pleasure...

Tada! A misaligned box though it is out only by 1mm on one panel so I'll take what I can get. Weird to think that that box is pretty much the main body of The Honey Badger 3 when compared to the vastness of the predecessor but it is a less is more approach here. Obviously, the screw pilot holes will need to be deepened + countersunk with at least 8 more needing to be added for strength.
The body still needs motor end caps on each end, the rails for the second deck to sit on and the fancy pants motors putting in but I put in the old motors and ESCs as a test to see what it looks like.
DSCF6365.JPG
You can't really see where the ESCs are but it is tight, they are right in front of the motors. The wooden jig underneath I placed a little deliberately to get a mock view of how long the rails need to be. The angle of the photo betrays this but the rails are out further at the back than they are at the front. When the new motors arrive, the wheels will need to be changed as the motors are taller than these by about 20 mm (which is also why the end caps haven't been done yet) but in theory, I could tape+wire this together now and see how it looks when moving.
Oh, and as an aside, the LEDs I ordered for Manchester turned up today! Yay, only 2 weeks late!Last edited by Ocracoke; 1 May 2018, 12:37.Comment
