The MAAT – 1 has been designed to walk on all
kinds of terrain. Its current
design can enable it to scale up to 3 in. high obstacles.
It was supposed to be capable of scaling up to 5 in. but due to its
shifting center of gravity it slips under its own weight.
We have no reliable measurement of the torque of the motor but we
believe it can climb vertically if it uses suction cups. The limiting factor
is the strength of the shafts and keys. We
believe that if we use a much lighter aluminum angle bar instead of a flat bar
it will be able to do so. It can only walk 20 degrees lateral to a slope the
limit is due to the bending of the legs.
Using lighter materials will also solve this problem.
The robot has a maximum speed of 2 meters per minute, increasing the
voltage up to 40 volts will further increase its speed. Finally, the legs are
still subject to modifications. Modifications
that will increase its mobility, durability and reliability
The design is original and has not been based
on existing legged robots due to the fact that existing designs are expensive
and its parts and components are scarce here in the Philippines.
Due to that fact, we are driven to make a robot design that is cheaper
and better. However the four –
bar mechanism that we used is based on the four – bar links of the six –
legged robot that was designed by Mark A. Tecson.
