Kaaz'min Robot Build Diary

Postby Kaazmin » Sat Aug 26, 2017 5:00 pm

so after conversing with Shakey and looking at error.exe's performance from AWS 52, I decided to completely re design the robot. Therefore I purchased a new battery as I needed to borrow one from Shakey in AWS 52 (thanks a lot btw). I have also upgraded the drive motors to 50:1 ratio motors so it's now a lot faster. However, the motor would not run on the new robot and it really did not hold up to the power I needed. Now with a new motor and a completely new design im ready to build the proper robot.

The design looks pretty good, and with a much beefier spinner motor! :D

Looking good, the new spinner blade and motor look much more dangerous!

Thanks a lot, I need a new disk as that one won't fit the new motor here's the new disk design compared to the old one. Image

Got the chassis complete

got a little problem with one of the wheel ESC's.( i use the finger tech tiny ESC v2.) at the moment its just got a continuous red light when powered and is not relaying to the motor its connected to. I've checked and replaced all the wires to the motor, and it's in an identical circuit to another ESC which is working. just wanted to check if anyone had any ideas before I just buy another one thinking it's broken.

It's looking good!

I'm not familiar with the tiny ESC's though so no idea what it is doing.

A simple one first: Try unplugging and replugging the cable into the receiver also and of course recharging the battery and trying with a fresh one.

And now more complicated fixes if that doesn't work:

Have you tried swapping the motors over? There could be a short on one of the motors causing the motor to continually stall or a different fault.

I can see from the specifications on the website for them (https://www.fingertechrobotics.com/proddetail.php?prod=ft-tinyESCv2 under the operation tab) that solid red means it's receiving the signal to reverse. Perhaps a stalling or otherwise faulty motor or connection could be causing the logic voltage to dip, meaning the chip does not respond properly and defaults to 'reading' the lowest pulse width or simply does not boot properly at all due to insufficient power. Just an educated guess really but definitely worth swapping motors over to eliminate that variable.

Potentially could also be due to this calibration setup mentioned on the site not being performed correctly. Unsure what they actually mean by that but definitely worth checking out the linked website; probably easier to understand when you have the hardware to hand.

Also, you could definitely remove the case from that receiver. Then, just put some electrical insulation tape around the outside to prevent shorting. Usually saves about 7g of weight which is a lot. It'll help you armour up and also make the internals more compact and easy to work with.

Loving the look of it! Best of luck; keep us all updated. :D

thanks a lot, I have tried switching and swapping over the motor it's on and the channel on the receiver and I still get the same problem. the battery is fully charged. it might be due to the calibration of the ESC. plus I have removed the casing from the receiver and covered it in masking tape to save weight ^-^. I'll have a proper look at the calibration stuff to see but yeah IDK what it is at the moment :P but it's definitely a problem with the ESC

I notice you had screw terminals in one of your photos. Maybe the power wires are not in fully. Perhaps try to restrip the wires and put them back in, maybe soldering together with others if possible.

for some reason on a full charge, my battery is only lasting about 1 minute ... https://hobbyking.com/en_us/turnigy-nano-tech-300mah-2s-45-90c-lipo-pack.html this is the one I use at the moment, anyone got any ideas ??
