my robot should have following moves
1)left treads(forward,backward)
2)right treads(forward,backward)
3)hands treads(forward,backward)
4)hand up& down(angular move)
5)total=8

Quote:
then hoe many channel is required and what kind of motor is siutable for forward &backward with high torque(more than 2AMP motors)
what is the best remote control for all of the movements how many channel is required?
total weight around 2k.g
where i can i get best remote control with cheaper rate

Quote:
qst2: stepper motor has several pole so it may as many channel to drive the motor ,is it?

the ic [SN754410
QUADRUPLE HALF-H DRIVER]i saw has 4 channel of providing 1AMP for each then how many stepper motor can by with that one ic?
finally which is suitable driver to drive six stepper motor (at least 4 sametime) with less area????????

Just don’t ask question there is lots of post in RI about stepper motors

Try google you will get lots of information about stepper motors

Stepper motors are NOT meant for weight bearing movement. It is bad engineering practice to do so.

Its essential that you use a DC geared motor.

You will need a minimum 5 channel Remote; 4 for navigation and the 5th for the Up/Down. You will need 6 channels , if you want independent Up- Down.

You can use Toy car remotes for this, but they are only 4 channels, low range and susceptible to interference.
Alternatively, you can make your own 6ch Remote, with ready-made 433MHz. Transmitter/receiver modules, Encoder/decoder ICs and some Logic gates.

The cheapest proffessional 6 channel Remote is expensive. It will cost you atleast 8000INR for a complete system with low range.

Sorry, vthangam: I thought it will be beneficial to all , if I answered your PM query on the Forum.
