Re: My first robot
Make sure you have good traction with the ground, enough ground clearance to be able to drive off wedges should you be got underneath, and a low front to get under other robots Hi Joey, are you saying you shouldn't design a robot with very little ground clearance? I see what you mean but I have alw...

Re: Charging batteries in series
Thanks for the advice, I have ordered 2 replacements and will keep these separated. My friend has a NiMH charger that may allow me to charge them slowly. I believe my charger is indeed "sulking" it is a Sky RC E4 and is showing warning light and refusing to even attempt to charge them. Kil...

Re: Charging batteries in series
I have left my robot on and drained the batteries after only 3 charges. From what I understand the charger looks for a voltage range before it will work. Can they be revived? My idea is to order 2 more and charge 1 dead with 1 good one to get the voltage up enough so they can then be charged indepen...

Re: Peter Wallers Robot Ramblings
P&P from Shapeways is about £8. It's gone up very steeply over the years, but that's still quite good value considering it's 24 hour delivery from Holland. The chassis cost all depends on how good a design you have. I personally try and limit myself to £30 per robot, and £40 for a clusterbot. I...

Re: Peter Wallers Robot Ramblings
Shapeways? What do they charge for an average chassis?

Re: Peter Wallers Robot Ramblings
Wow, these look great. Very professional, it's amazing how good they can look with the 3D printed parts. Do you own your own printers or send them away to be done? I've had parts made for work and it's not that cheap.

Re: New B: First post, First RC, First robot
Thanks for the advice, I must admit the wheels are a bit overkill but they fit perfectly on the motor shafts and appear to gave a lot of grip, I would hate to have to replace them with a bottletop or such like. Let's do a full weigh in and see how we get on. I will have a play with the trimming and ...

Re: New B: First post, First RC, First robot
Hi Joey, I had another look and my temporary chassis measures 120 x 150 so a little oversize. The chassis is 1mm ALU with a 2mm display board top. Once I have my final design worked out I may switch to polycarbonate. I didn't realise how tough it is getting to weight.

Re: New B: First post, First RC, First robot
It works, I connected it all up today on a temporary chassis and apart from some channel reversing it was fine. The only issue I have is that it doesn't drive in a straight line, not sure if this is a bent chassis or one wheel is running faster...any ideas? I am also at around 175g even with a card ...

Re: Charging batteries in series
Thanks for the advice. I have successfully soldered up some tiny JST pH sockets that allow me to plug in each 1c battery indepentally although they are in series on the robot. Both charged within 1hr so no problem there.
