and some part of the drive train in contact with the ground will have to slide or skid. Driving straight in one direction requires at least one single direction actuator. A wind-up toy is a good demonstration of this ultra-simple drive system. Driving straight in both directions requires at least one bidirectional actuator or two single-direction actuators. One of those single direction actuators can power either a steering mechanism or a second drive motor. Add one more simple single-direction motor to the wind-up toy, and it can turn to go in any new direction. This shows that the least number of actuators required to travel in any direction is two, and both can be single-direction motors. In practice, this turns out to be quite limiting, at least partly because it is tricky to turn in place with only two single direction actuators, but mostly because there aren t enough drive and steer options to pick from to get out of a tight spot. Let s investigate the many varieties of steering commonly used in wheeled and tracked robots. The simplest statically stable vehicle has either three wheels or two tracks, and the simplest power system to drive and steer uses only two single-direction motors. It turns out that there are only two ways to steer these very simple vehicles: 1. Two single-direction motors powering a combined drive/steer wheel or combined drive/steer track with some other passive wheels or tracks 2. Two single-direction motors, each driving a track or wheel (the third wheel on the wheeled layout is a passive swivel caster) The simplest version of the first steering geometry is a single-wheel drive/steer module mounted on a robot with two fixed wheels. The common tricycle uses this exact layout, but so do some automatic guided vehicles (AGVs) used in automated warehouses. Mobility is limited because there is only one wheel providing the motive force, while dragging two passive wheels. This layout works well for the AGV application because the warehouse s floor is flat and clean and the aisles are designed for this type of vehicle. In an AGV, the drive/steer module usually has a bi-directional steering motor to remove the need to turn the drive wheel past 180 but single direction steer motors are possible. There are many versions of AGVs the most complicated types have four drive/steer modules. These vehicles can steer with, what effectively amounts to, any common steering geometry; translate in any direction without rotating (commonly called crabbing ), pseudo-Ackerman steer, turn about any point, or rotate in place with no skidding.

for AGVs are available independently, and come in several sizes ranging from about 30 cm tall to nearly a meter tall. The second two-single-direction motor steering layout has been successfully tried in research robots and toys, but it doesn t provide enough options for a vehicle moving around in anything but benign environments. It can be used on tracked vehicles, but without being able to drive the tracks backwards, the robot can not turn in place and must turn about one track. Figure 6-4 shows this limitation in turning. This may be acceptable for some applications, and the simplicity of single direction electronic motor-driver may make up for the loss of mobility. The biggest advantage of both of these drive/steering systems is extreme simplicity, something not to be taken lightly.
The Next Step Up
The next most effective steering method is to have one of the actuators bi-directional, and, better than that, to have both bi-directional. The Rug Warrior educational robot uses two bi-directional motors one at each wheel. This steering geometry (Figure 6-5a, 6-5b) is called differential steering. Varying the relative speed, between the two wheels turns the robot. On some ultra-simple robots, like the Rug Warrior, the third wheel does not even swivel, it simply rolls passively on a fixed axle and skids when the robot makes a turn.
