This quadrotor is the best flying robot I have ever seen. Just watch the videos, you will be amazed by its great Maneuverability, and all the cool things it can do :)

Hello,

I am working on making a tiny obstacles avoiding robot (with the picaxe 08m). The robot use small dc motors to move and a MaxSonar sensor to detects objects.

The problem is that when I set all pins on the picaxe chip to low, the motors movie in pulses, as if its somehow picking up the pulses from the sensor.

Here is my schematic:

Hello,

I am having trouble connecting the L298N to my picaxe 28x starter pack.

Here are my connections:       ( Sorry for the drawing, I don't have any fancy software :) )

(The Picaxe uses a seperate power supply)

When I set the output pin to high, nothing happens. I am not sure wither I should connect GND on the L298N to GND on the picaxe board and have no idea what is the CURRENT SENSING pin.

Hello,

I have two of these Tamiya 72001 Planetary Gearbox Kit, I am using them with my picaxe 28x1 starter kit.

The manual says "Do not use power source higher than 4.5V". However, the motor doesn't work with a power source lower than 6v, and even with 6V the motor barely moves and the motor drive (L293d) become extremely hot and after a few second of use it seems to shut down and the motor stops moving.

Will using 3C batteries instead of 4AA slove the problem?

Thanks.

Hello,

I want buy a motor and a servo controller, but before I buy it, I thought I should ask some questionst:

1) I know that you can use a separate power supply for the servos on the picaxe 28x1 starter kit, but can I use a separate power supply for the motors or do I have to use a motor controller.

2) Can I use any servo or motor controller with any microcontroller, or is there is a specific motor controller for picaxe or arduino etc.

Thank you.

Hello.

How to use a sensor that doesn't required an analog-to-digital converter (ADC)? Like the Pololu QTR-1RC Reflector Sensor. I am using a picaxe 28x1 (Starter Kit). 

This has been discussed here http://letsmakerobots.com/node/5228 but no solution.

Here is the product information http://www.pololu.com/catalog/product/959

Thank you.

Hello.

I am trying to connect the SRF05 to a picaxe 08M (starter kit). But it doesn't seem to work. I know how to connect the SRF05 to a picaxe 28x1.

Here is the program I used:

main:
pulsout 4, 2
pulsin 3, 1, w0
pause 10
debug
goto main

Thank you.
