I would check out the grounding of the robot, to avoid any
floating RF. Shielding may help. Keep me posted....

I would agree with pkott716, with the power supply problem. I would try a battery,
and if that did not work, I would email ServoCity about the issue, to make sure they
sent me the motor that I ordered, and that I did not expect this action form this motor.
Keep me posted....

I followed admin of this website's voice recognition car steps. He has it on his website that how to build the voice recognition car. I followed every single step and did exact the same thing he showed on his website. But still I cannot complete my programming because I am a high schooler and I just wanted to complete my project for Science Fair. This is the website by admin:http://www.societyofrobots.com/axon2/axon2_setup1.shtml

A complex question, to be sure.
The answer lies in the complexity of the robot. The more "layers"
of programming and MCUs, the more systems that can inhibit
In the case of the scenario you indicated, I would think that Baymax had
"learned" what had happened, and did not want to be rebooted. Back in the day,
there was ROM, (Read Only Memory)
which could not be written over.
I would hope, in the fiction or fact world, that the main "overseeing"
AI that controls the robot is not damaged, and maintains a divine
integrity.(assuming the robot is good, of course. NOT Ultron!)

Have you tried running it from a battery instead of a power supply and see if the problem continues? Sounds like a power supply problem to me.

Ide never considered the flicker,
To add some more info to this, the bot is controlled currently from a 2.4ghz 5 channel RC transmitter, the camera is a HTC Droid Incredible 2, running an app to stream through the network to a local IP address. The current setup works beautifully, but instantly when I turn the transmitter on, the video freezes. I know they make dual band routers that work on 2.4ghz as well as 5ghz, would this potentially solve this interference?
I guess I don't understand why they would interfere with one another, pretty much everything in a home runs at 2.4ghz, microwaves, televisions, etc and they don't have any effect on the signal.
Would making the bot controlled by the web via WiFi instead of a transmitter stop the interference?
Just looking for a little helpful banter, thanks again.

I forgot to include that the problem exists without a load on the motor. The motor has 305.5 oz-in torque.

Hi. This should be an easy solution, but I'm very electronically illiterate. I'm not building a robot, but I'm using a DC motor that I bought from Servocity for my project. I wired the 12v motor directly to the 12v DC power supply; however, the motor will run for approximately .5 seconds and then shut off for .5 seconds and then cycle through again, effectively causing the motor to pulse. I just need it to run constantly. Since there are no electronics between the motor and the power supply and there are no electronics on the motor itself, I'm not sure what is happening. The specs on the motor are:
Operating Voltage Range: 6~12VDC
Rated Voltage: 12VDC
Rated Load: 3.2 kgf-cm (44.4 oz-in)
Operating Temperature: -10 ~ +60°C
Max No-Load Current: 0.52A
No-Load Speed: 437 RPM
Min. Stall Torque: 22 kgf-cm (305.5 oz-in)
Max. Stall Current: 20A @ 12VDC
Dielectric Strength: 250 VAC
Motor Brush Type: Graphite
Output Power at Max. Efficieny: 13W
Gear Type: Planetary
Gear Ratio: 19:1
Bearing Type: Dual Ball Bearing
Shaft size: 6mm (0.236”)
Net Weight: 330g (11.64oz
The Power supply specs are:
Input Voltage: 100-240Vac
Input Plug: USN
Case: Wall Plug in
Input Current: 0.8A max
Output Volts: 12 VDC Regulated
Output Current: 2500 mA
Power Rating: 30 Watts
Dimensions: 88 x 58 x 48mm (Case)
Any help on an affordable way (less than $20) to keep the motor running continuously would be appreciated. Thanks.

Is it a problem with the flicker selection? I know some places power frequencies are 50hz while others are 60hz. Maybe something is set for 50 when it should be 60 and the result of that flicker is the cause of that video feed stopping.
I don't know, one of my webcams is always asking me if I live in a 50 or 60 hz area and the reason for the question is to avoid flickering.

Hello All! I've finally had some time to start on my virtual presence bot, its running and driving wonderfully. However, I have a ton of interference when I try and use a 2.4ghz Wi-Fi camera, every time the transmitter turns on, the video feed stops instantly, is there anyway to remedy this? Thanks in advance!
