The key design visions (goals) for the next model (AIMEC:4) are very different. This robot is targeted as a mass market (high volume) robotic appliance (a useful general purpose Personal Robot). We already have face recognition working well, and we are now quite advanced with object recognition. This now opens the robot to serious applications, as vision has been the main stumbling block until now. When a robot can recognise an object, it can do useful work.
Before this, robots had to be in structured environments, where everything had to be in the right place. With the first AIMEC:4 vision system, we already have the robot seeing the difference between 'Diet' and 'Regular' coke cans, so a robot like this could go to a fridge, find and extract the right can! The AIMEC:4 will have much stronger arms and claws, so will have the ability to work with more intricate and heavier workloads. However, the cost of this new machine will be higher than AIMEC:3.
