Team Coolspeedbot: first feather weight robot

[Coolspeedbot]

So I’ve been using Wolf-E’s test platform to help get a sense of scale with parts yet to be added such as the Lipo battery mocked up in cardboard.

I came to the conclusion that it’s possible to add 2 more 12volt motors and using HDPE. I can make a 4WD weaponless CSB instead of Wolf-E.

Don't Worry this thick-o work it out I had to set one of the mixes to -100% to get it to work

[Coolspeedbot]

So the Receiver and drive mystery thickens. When I mix the Aile and elev channels through the mix 1, mix 2 and the V-tail mix on my DX6i the rudd channel suddenly has control over the left motor. The only way the mixing works is not using mix 1, 2 and V-tail mix and instead use Elevon mix instead. is this normal? or is something busted?

You can get extra long shafts for the Banebots P60 gearbox; making your own shafts is a precision job that needs both a lathe and a mill.

oh thats handy.

Personally I'd go with the first one, because a) it's harder to get high reduction out of pulleys (the gearbox will likely be much higher and won't slip) and b) I like Sewer Snake, and that's how they do it. :P

I had figured that would be a factor but I'll need to mod the gearboxes to have extended drive shafts to support the whole wheel and pulleys.

Pondering on drive configuration. Wither to go with gearboxes directly running the middle wheel and connect the front and rear wheels through pulleys.



Or run the brushless motors to the rear wheels with another pulley and then run pulleys to the middle and front wheels.

[Coolspeedbot]

So I went to do the test run and... the receiver is busted. I had to check both motors, both ESCs until I found the fault that was stopping both motors from running at the same time. It appears one of the channels used for drive on the receiver is not working. At least it's a cheap part to replace.

[Coolspeedbot]

Motors are now mounted and the wiring connected. Hopefully will get a test drive tomorrow.

[Coolspeedbot]

And now for something completely different.

Spent the past day and today working on one pair of motor mounts made out of HPDE scrapes. Hoping to get the other side done tomorrow and monday so I can have a working test platform to fully test the drive of Wolf-E.

Yeah just send them a dxf or dwg drawing and they can cut it in pretty much anything. They have a lot of material on stock so best to ask them what thicknesses they have before designing something. For hardox I think it's 4,6,8,10,35,40mm

[Ocracoke]

Ah right, so you can specify a CAD design with a specification of what sort of material and thickness you are after and they water cut it? Fair enough, worth bearing in mind.

[Coolspeedbot]

K-cut source their own hardox for water cutting

[Ocracoke]

Out of curiosity (for my next robot), where are you sourcing the Hardox from?
