We are getting down to some of the nitty gritty. To a considerable extent
what is holding robotics back is the lack of common standards. We can think
about what we might need. One would instinctively start with a CAD/CAM
package like ProEngineer. We can thus descibe a robot in terms of assembles
and parts. A single joint is a part, a human finger has 3 joints is an
assembly. A hand is an assembly. We get this by using CAD.
A robotic language has to be composed as follows.
class Part{
}
class Assemble{
}
An assembly/part will have a position. The simplest command is to move from
one position to another. Note that a position is a multidimensional quantity
and describes the positions of each part.
"*Pick up ball*" is a complex command. We first have to localise the ball,
determine the position required to grasp the ball any then put the parts
into a position so that the ball moves into a new position.
Sounds complicated? Yes it is, but a lot of the basic work has already been
done. The first time a task is performed the system would have to compute
from first principles. The second time it would have some stored positions.
The system could "*learn*".
A position is a vector (multidimensional) 2 robots will have twice the
dimensions of a single robot.
"*Move bed upstairs*" is a twin robot problem, but no different in principle
from a single robot problem. Above all I think we must start off
mathematically and construct a language of maximum generality. It should be
pointed out too that there programs which will evaluate forces in a
multi-limb environment. In fact matrix theory was devised in the 19th
century.
