Here is a cool gift idea for those who are into battlebots. The FingerTech ‘Viper’ Combat Robot Kit has a 6061-T6 aluminum chassis. It uses 2 x FingerTech “Silver Spark” 33.3:1 ratio gearmotors with 2.25″ snap wheels. It has a 3mm thick front wedge and 1.5mm top armor made of polycarbonate.
This robot measures 6.5 inches wide and 5.5 inches long. It uses a JST-to-9 V Battery adapter.
