Lizard Inspired Tail for the Dynamic Stabilization of Robotic Bodies
Lizard Inspired Tail for the Dynamic Stabilization of Robotic Bodies A Major Qualify Project Report Submitted to the Faculty of WORCESTER POLYTECHNIC INSTITUTE in partial fulfillment of the requirements for the Degree of Bachelor of Science In Mechanical Engineering By Michael Berlied _______________ Approved by: Stephen Nestinger ______________ Date Completed: April 27, 2012 ABSTRACT The purpose of this project was to determine the feasibility of a lizard inspired tail for the dynamic stabilization of robotic bodies during aerial or aggressive maneuvers. A mathematical model was created to determine the effects of various tail designs. A physical model of the tail design was fabricated and used to determine feasibility of the design and evaluate the mathematical model. ii Table of Contents Abstract ........................................................................................................................................... ii Table of Figures .............................................................................................................................. v 1.0 Introduction ............................................................................................................................... 1 2.0 Methodology ............................................................................................................................. 2 3.0 Literature Review...................................................................................................................... 3 3.1 Lizard Physiology and Tail -

The genus comprises 17 species (Leaché and 2008; Sigala-Rodríguez et al., 2008; Sigala-Rodríguez McGuire, 2006; Nieto-Montes de Oca et al., 2014) and Greene, 2009).

The Effects of Burning and Grazing on Survival, Home Range, and Prey Dynamics of the Texas Horned Lizard in a Thornscrub Ecosystem
The Effects of Burning and Grazing on Survival, Home Range, and Prey Dynamics of the Texas Horned Lizard in a Thornscrub Ecosystem Anna L. Burrow1, Richard T. Kazmaier1, Eric C. Hellgren1, and Donald C. Ruthven, III2 Abstract.—We examined the effects of rotational can increase the amount of woody vegetation (Archer livestock grazing and prescribed winter burning on the and Smeins 1991). Ruthven et al. (2000) found that state threatened Texas horned lizard, Phrynosoma forbs increased on southern Texas rangelands in the first cornutum, by comparing home range sizes, survival year after a winter burn, but were not affected by estimates and prey abundance across burning and grazing. Bunting and Wright (1977) also found that grazing treatments in southern Texas. Adult lizards were forbs and grass cover increased following fire. Ants, the fitted with backpacks carrying radio transmitters and main prey of horned lizards, are not deleteriously relocated daily. Prey abundance (harvester ants, affected by fire or grazing (McCoy and Kaiser 1990; Pogonomyrmex rugosus) and activity were greater in Heske and Campbell 1991; McClaran and Van Devender burned pastures, but grazing had a variable effect 1995:165 Fox et al. 1996). depending on the timing since the last burn. Home ranges in burned pastures were smaller than in Specific objectives of our research were to: compare the unburned pastures in the active season. Level of grazing relative abundance and activity of harvester ants, (heavy vs. moderate) did not affect home range size. Pogonomyrmex rugosus, the main food source of the Texas Summer survival rates of horned lizards were higher in horned lizard, among different burning and grazing the moderately grazed sites than the heavily grazed sites. -

Of course, we are looking forward to the re-opening of Mitchell Lake Audubon Center sometime this fall so we can see birds and our fellow birders in person and stretch our birding brain cells while keeping our social distance. Great Texas Birding Classic: Another opportunity is the 24th Annual Great Texas Birding Classic, postponed this spring due to health concerns, but now rescheduled for October 1-31. With new rules and birding team categories, it still supports Texas Parks & Wildlife bird and birding conservation project grants while meeting pandemic health guidelines. Take a look at the GTBC website, put together a team, pick a date in October that works for you, and get out there!

MANAGEMENTOFTEXASHORNEDLIZARDS ScottE.HenkeandWm.ScottFair ResearchScientists CaesarKIebergWildlifeResearchInstitute TexasA&MUniversity-Kingsville,Kingsville,Texas78363 Abstract: Texas horned lizards are declining in abundance and distribution in Texas. There are no obvious causes for their decline; however, multiple factors such as widespread pesticide use, habitat loss, over-collection, and fire ants have been suggested as possible reasons. Texas horned lizards are a threatened species in Texas and are listed as a Federal Species of Concern. The ecology and habitat requirements of Texas horned lizards are outlined in this paper and management practices are sug- gested that should benefit this species. INTRODUCTION TAXONOMY AND DESCRIPTION The Texas horned lizard is a part of the history Much like the bandits of western folklore, Texas and culture of Texas. In fact, most Texans have fond horned lizards have used many aliases. Two of the memories of growing up with Texas horned lizards. most commonly-used misnomers are horned toads Horned lizards are as much of Texas folklore as cow- and horned frogs. However, Texas horned lizards boys, longhorns, the Alamo, and listening to coy- are, as their true name implies, lizards! Toads are otes howl at the moon. Unfortunately, many young tailless amphibians with rough, warty skin and live Texans have not experienced the thrill of seeing a on moist land or in water (i.e., during breeding). horned lizard in their backyard. This is because the Frogs also are tailless amphibians but have smooth Texas horned lizard population has declined in Texas skin and are equally adapted to land and water. over the past couple of decades.
