COMBAT ROBOT Selection Guide


      

Vantec has many winners in Battlebots, Robot Wars and some educational fare wins. Most purchases for Battlebots or competitive "tank style" steered robots use our RDFR series which is a complete DUAL speed controller including mixing for vehicles with right/left motors.  These successful designs and actual examples understand the importance of optimized gearing to achieve an efficient operating RPM for the motor. 

This Selection Guide includes provision for over-voltaging the motor and anticipates your 'bot will properly gear a pair of motors OR perhaps a total of 4 or 6 motors. When there is more than one motor per side consider how to wire the motors. Motors that are hard coupled via gears, sprockets and shafts must be wired in series to force them to share the torque load. That means the battery voltage required is motor voltage intended times number of motors series'ed. The current load is that of a single motor.  For hard coupled designs consider that using one proper sized motor is usually more efficient than coupling two smaller motors.

On the other hand if there are two right side motors each independently coupled to it's own wheel, the motors should be wired in parallel. Parallel wired motors will be powered by a battery voltage equal to the intended motor voltage but the current draw will increase by the number of motors on a side.

If you are building a heavywight or using extreme motors this Guide may recommend RSFR single controllers.  Two of the singles may be operated independently and still may utilize the mixing function.
