The Sir Killalot radio controlled toy was the most expensive of the House Robots, priced at around £79.99-£89.99. It was quite fast and has a recharge time of five hours. Rather disappointingly, the caterpillar tracks don't move. Instead, two larger wheels beneath the toy at the center drive the robot while two single caster wheels provide balance and help the toy turn. However, this gives the robot a maneuverability advantage as it can turn very fast in any direction without moving forwards or backwards and it can also spin at incredible speed. The eyes also light up when the robot moves in any direction.
