Query: Sliding Mode Control for Mixed Conventional/Braking Actuation Mobile
  Robots   The Mixed convention/braking Actuation Mobile Robot (MAMR) was designed to
tackle some of the drawbacks of conventional mobile robots such as losing
controllability due to primary actuator failures, mechanical complexity,
weight, and cost. It replaces conventional steering wheels with braking
actuators and conventional drive wheels with a single omni-directional wheel.
This makes it fall under the category of under-actuated mobile robots. The
brakes have only two states, ON and OFF, resulting in discontinuous dynamics.
This inspires the use of a discontinuous control law to control the system.
This work presents a Sliding Mode Controller (SMC) design to park the MAMR
system from a given initial configuration to a desired final configuration.
Experimental results are presented to validate the parking control of the MAMR.
