This carrier plate is made out of durable Lexan and allows you to mount either a BR-KT base rotate kit or the HDMAB Heavy Duty Metal Base to a VEX plate. This is particularly useful for Project Lead The Way (PLTW) as both Lynxmotion arms and VEX products are used. The plate also includes mounting holes for the SSC-32/32U or BotBoarduino as well as holes for the aluminum bracket used on the Base Electroics Carrier Kit. Hardware to mount the base as well as the electronics is included. Hardware to mount the Lexan plate to a VEX plate is not included.
