“…There are suits that are equipped with devices and the handler can monitor the dog's location or environment, interact with the dog or give instructions to the dog. Suits were presented that were equipped with GPS to measure the position of dogs [2], [3], [4], [16], [17], [18], suits that equipped with camera to know environment of dogs [4], [5], [17], [18], [19], suits that communicate with handlers by biting and tugging [16], [20], communicate with voice or sound [2], [3], [4], suits giving instruction with vibration [2], [3], [4], [21], [22], and suits guiding dog with an attached light source [5], [6]. Controlling canine's motion by sounds and vibration devices attached to a canine suit has been studied.…”

“…By irradiating the ground with light, it is possible to convey the direction in which the operator wants the canine to go. It was proposed a method of guiding a canine by mounting laser light devices on a canine suit [5], [6]. In this research, we developed a spotlight device that is small enough to be mounted on a suit and can be controlled remotely but is bright enough to be seen outdoors.…”

“…Shoulder was selected as the spotlight device location. In this case, the horizontal distance from the canine's eyes and the spotlight is 1 m because canine can see the light more easily at this irradiation angle [5]. Therefore, irradiation length b was determined to be 1,280 mm, as shown in Fig.…”

“…To control canine motion remotely using light, the light devices must move with the canines and irradiate lights in different directions. Therefore, we developed a canine suit equipped with several laser beams and evaluated its performance using both canines who were trained to chase a light spot and those with no training [5]. In this system, their trajectories were controlled remotely by switching among these lights on the suit.…”

Engineering to produce stimuli that trigger an organism's habits allows us to control it noninvasively. Because canines already have the habit to follow a light spot, light is a good stimulus for controlling their motion. We employed green laser beams to successfully control canine motion indoors. We developed a suit equipped with laser beam devices that face front, left, and right. The canine wore the suit and followed a light spot on the ground. Its trajectory was controlled remotely by switching the lights on the suit. However, this laser beam spot was too weak and small to be visible in grassy fields outdoors. Here, we propose a spotlight device that irradiates a bright and large spot (70 mm in diameter) for outdoor environments. The proposed spotlight device consists of a high brightness LED and a convex lens. To evaluate its performance, we conducted indoor and outdoor experiments using three canines. In the indoor experiments, the success rates of controlling the canine's motions were 100%, 83.3%, and 93.3% for each of the three canines, respectively. In outdoor experiments, these rates were 100%, 57.1%, and 62.5%, respectively. Hence, the proposed spotlight devices are effective for controlling a canine even in outdoor environments.
