, I am making a robot for track race.But having some problems.
I am using 4 DC motors 12v 300 rpm and 2 kgcm torque each (this one: http://www.vegarobokit.com/product_descriptions.aspx?product_id=74&sub_category_name=Gear%20Motors&category_id=41
) and the whole robot is little less then 1 kg(1 kg is max weight allowed).Now the problem.
There is a 30 degree slope which the robot must climb. There is a plastic bag which is on stuck on the face of slope using tape. Then a layer of oil is applied in the face of the bag making it slippery.
What happened? Well we took the max run up we could(about 1 foot) went at full speed but only made it 3/4 up, before our bot came down the slope.I got to make
some bot that turn and every thing and also climb slopes. I don't have much experience (its the first thing i made that moves) so i got some questions?
What is better 4 small motors and 3 wheels or 2 big motors and 2 wheels?
what better bot as lite as possible or bigger motors(which are more powerful but also weigh more)?
how balance speed and torque (it cant be slow but need to climb to slopes)
any other to help me win tipsthe rules for race
are 25cm*25cm*25cm max size, 1kg max weight, external power source will be provided(it means there is a 5 meter long wire going form robot to remote and the to dc adapted is no batteries )
