- Description: This report will show the development of a Delta Parallel robot, to aid in teaching the basics of robotic motion programming. The platform developed will be created at a fraction of the cost of conventional commercial training systems. This report will therefore show the development procedure as well as the development of some of the example training material. The system will use wireless serial data communication in the form of a Bluetooth connection. This connection will allow an Android tablet, functioning as the human-machine interface (HMI) for the system, to communicate with the motion controller. The motion controller is based in the C environment. This will allow future development of the machine, and allow the system to be used on an integral level, should the trainers require an in depth approach. The motion control software will be implemented on a RoBoard, a development board specifically designed for low- to mid-range robotics. The conclusion of this report will show an example task being completed on the training platform. This will demonstrate some of the basic robotic motion programming aspects which include point to point, linear, and circular motion types but will also include setting and resetting outputs. Performance parameters such as repeatability and reproducibility are important, as it will indirectly show the level of ease with which the system can be manipulated from the software. Finally, the results will be briefly discussed and some recommendations for improvements on the training system and suggestions for future development will be given.

- Description: The aim of this study was to explore the perceptions of RDP beneficiaries on the extent to which the RDP housing project meets their housing needs in South Africa through a case study of Golf Course Estate in Alice Town with the following specific objectives; to assess the extent to which the Alice Golf Course housing project has achieved the RDP programme objectives; to establish beneficiaries‟ perceptions on the extent the RDP Alice Golf Course houses meet their needs; and to explore the level of satisfaction on the RDP houses by beneficiaries. This study utilized triangulation of both quantitative and qualitative methodologies with qualitative as the dominant approach while quantitative was less dominant. The qualitative design took the form of a case study while the quantitative took the form of mini survey. The study sampled 72 participants from the study population. The study utilized an interview guide and a questionnaire as instruments of data collection. The findings indicated that the gender representation of the beneficiaries was skewed. This is because there were more females heading the houses than males; unemployment was also high; most participants were unmarried and most were adults. This study also discovered that most people residing in these houses are not the real owners who were allocated the houses. There were qualitative problems associated with the components of these houses such as poor roofing, doors, windows, floors and walls. Service delivery complaints were based on inadequate access to clean water, small size and spacing of the RDP house. Security was also a challenge because all the houses did not have street lights and the roads were very bad. Though it is commendable that drainage and sewer facilities are available, but they are not serving their purpose since there is no water in these houses. The findings also indicated that there were discrepancies in allocation of the houses; pervasiveness of social ills; inadequate consultative meetings between the RDP Administrator or social worker and the beneficiaries; as well as the pervasiveness of HIV/AIDS among other issues. This researcher recommended that the government needs to promote economic empowerment to deal with unemployment; to improve the quality of the material building the houses; improvement on service delivery gaps; to beef up infrastructure; renovation and revamping of current houses; to establish commissions of inquiry to deal with corruption; to honour and monitor waiting lists. Partnership with other stakeholders was also critical, in addressing access to social services and helps deal with social ills and run behaviour modification campaigns. This researcher also recommended that there is a need to carry out further research on the role played by the municipalities in the RDP housing project as well as conducting a purely qualitative research to further explore the perceptions of other stakeholders, NGOs, traditional leaders, church leaders, and police on the implementation of the housing project. This researcher advises that such a research could be carried out through focus group discussions and also since this study was bound by a case study it is also necessary for similar research to be carried out in different places in South Africa.
