    Keywords : Mars; rover; wheels; planetary rover wheels; flexible wheels; rigid wheels;

    Abstract : This thesis looks at the SherpaTT planetary rover. The rover is a hybrid walking and driving rover that has been developed and built by DFKI and has already been deployed on several Mars analogue field studies. The SherpaTT rover wheels were found to become entangled in rocks during the last field deployment in Morocco. READ MORE

  3. 2. Dynamic simulation of a planetary gear for robots

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Xiaohao Qin; Jiahao Cheng; [2019]
    Keywords : dynamic simualtion; robots; PGT; solidworks; MATLAB;

    Abstract : Gear drives are widely applied in mechanical transmission systems and very accurate transmission systems are needed. In the robot industry, the planetary gear train (PGT) is commonly used to promote the torque transmission. One of the advantages of an ideal PGT is that the incoming torque is divided equally among the planet gear wheels. READ MORE

  6. 5. Plantetablering och tillväxt för sådd och planterad tall 2-5 år efter markberedning med harv eller Huminmix-teknik inom Holmen Skog distrikt Norsjö

    University essay from SLU/Dept. of Silviculture

    Author : Håkan Åström; [2006]
    Keywords : maskinell skogssådd; skonsam markberedning; skogsföryngring; tall;

    Abstract : The objective of this work was to compare the environmentally gentle soil scarification technique Huminmix (with possibilities to do track-grinding/HMMspår, long-scraping/HMMlångfläck and mounding/HMMhög) with conventional disc trencher, concerning seedling establishment and growth of direct seeded and planted Scots pine seedlings. Inventories were made during June and July 2005, in 34 seeded and 6 planted stands from 2000 – 2004 (1- 5 years old) of lichen- and myrtillus/vaccinum-type in Holmen Skog AB´s district Norsjö in Västerbotten.
